In [[Religion in ancient Rome|ancient Roman religion]] and [[Roman mythology|myth]], '''Janus''' ({{IPAc-en|ˈ|dʒ|eɪ|n|ə|s}} {{respell|JAY|nəs}}; {{langx|la|Ianvs}} {{IPA|la|ˈi̯aːnʊs|}}) is the [[List of Roman deities|god]] of beginnings, gates, transitions, time, duality, doorways,<ref>Varro apud Augustine ''De Civitate Dei'' VII 9 and 3; Servius ''Aen.'' I 449; Paulus ex Festus s. v. Chaos p. 45 L</ref> passages, frames, and endings. He is usually depicted as having two faces. The month of January is named for Janus (''[[Ianuarius]]'').<ref>Forsythe, ''Time in Roman Religion'', p. 14.</ref> According to ancient Roman farmers' almanacs, [[Juno (mythology)|Juno]] was mistaken as the [[tutelary deity]] of the month of January,<ref>[[H.H. Scullard]], ''Festivals and Ceremonies of the Roman Republic'' (Cornell University Press, 1981), p. 51.</ref> but Juno is the tutelary deity of the month of June.
Janus presided over the beginning and ending of conflict, and hence war and peace. The gates of a building in Rome named after him (not a temple, as it is often called, but an open enclosure with gates at each end) were opened in time of war, and closed to mark the arrival of peace. As a god of transitions, he had functions pertaining to [[List of Roman birth and childhood deities|birth]] and to journeys and exchange, and in his association with [[Portunus (mythology)|Portunus]], a similar harbor and gateway god, he was concerned with travelling, trading and shipping.
Janus had no [[flamen]] or specialised priest ''([[Glossary of ancient Roman religion#sacerdos|sacerdos]])'' assigned to him, but the King of the Sacred Rites ''([[rex sacrorum]])'' himself carried out his ceremonies. Janus had a ubiquitous presence in religious ceremonies throughout the year. As such, Janus was ritually invoked at the beginning of each ceremony, regardless of the main deity honored on any particular occasion.{{citation needed|date=November 2017}}
While the [[religion in ancient Greece|ancient Greeks]] had no known [[interpretatio graeca|equivalent]] to Janus, there is considerable overlap with [[culsans|Culśanś]] of the Etruscan pantheon.
== Etymology ==
The name of the god ''Iānus'', meaning in [[Latin]] 'arched passage, doorway', stems from [[Proto-Italic language|Proto-Italic]] ''*iānu'' ('door'), ultimately from [[Proto-Indo-European language|Proto-Indo-European]] ''*ieh₂nu'' ('passage'). It is cognate with [[Sanskrit]] ''yāti'' ('to go, travel'), [[Lithuanian language|Lithuanian]] ''jóti'' ('to go, ride'), [[Irish language|Irish]] ''áth'' ('[[Ford (crossing)|ford]]') or [[Serbo-Croatian]] ''jàhati'' ('to ride').{{Sfn|de Vaan|2008|p=294}}<ref>Taylor, Rabun, "Watching the Skies: Janus, Auspication, and the Shrine in the Roman Forum," ''Memoirs of the American Academy in Rome'' vol. 45 (2000): p. 1.</ref>
Iānus would then be an action name expressing the idea of going, passing, formed on the root *yā- < *y-eð<small>2</small>- theme II of the root *ey- go from which eō, ειμι.<ref>Objections by A. Meillet and A. Ernout to this etymology have been rejected by most French scholars: É. Benveniste, R. Schilling, G.  Dumezil, G. Capdeville. The enlargement of root *ey- into *ya- is well represented in Western Indo-European, as e. g. in Irish āth ,*yā-tu-s ford: cf. J Pokorny ''Indogermanisches etymologisches Wörterbuch'' I Berne-Munich 1959 p. 296 s. v. i̯ā and ''Thesaurus Linguae Latinae'' s. v. ianus.</ref> Other modern scholars object to an [[Proto-Indo-European language|Indo-European]] etymology either from Dianus or from root *yā-.<ref>A. Meillet DELL s.v. Ianus; A. Ernout "Consus, Ianus, Sancus" in ''Philologica II'' 1957 p. 175: Ernout takes into consideration the legends of the Thessalic origin of Janus too.</ref>
From ''Ianus'' derived ''ianua'' ("door"),<ref>F. Altheim History of Roman Religion London 1938 p. 194; V. Basanoff Les dieux des Romains Paris 1942 p. 18.</ref> and hence the English word "janitor" (Latin, ''ianitor'').
== Ancient interpretations ==
Three etymologies were proposed by ancient erudites, each of them bearing implications about the nature of the god.<ref>G. Capdeville "Les épithètes cultuelles de Janus" in ''MEFRA'' '''85''' 2 1973 p . 399.</ref> The first one is based on the definition of Chaos given by [[Paul the Deacon]]: ''hiantem'', ''hiare'', "be open", from which the word ''Ianus'' would derive by the loss of the initial aspirate. In this etymology, the notion of Chaos would define the primordial nature of the god.<ref>Paulus above : "Chaos appellabat Hesiodus confusam quondam ab initio unitatem, hiantem patentemque in profundum. Ex eo et χάσκειν Graeci, et nos ''hiare'' dicimus. Unde Ianus detracta aspiratione nominatur id, quod fuerit omnium primum; cui primo supplicabant velut parenti, et a quo rerum omnium factum putabant initium". [[Hesiod]] only reads (''[[Theogony|Theogonia]]'' 116): "Ή τοι μεν πρώτιστα Χάος γένετο..."; cfr. also Ovid ''Fasti'' I 103 ff.</ref><ref>An association of the god to the Greek concept of Chaos is considered contrived by G. Capdeville, as the ''initial'' function of Janus would suffice to explain his place at the origin of time. See: G. Capdeville "Les épithètes cultuels de Janus" in ''[[Mélanges de l'École française de Rome]], (Antiquité)''  '''85''' 2 1973 p. 399-400; Capdeville mentions also Varro apud Augustine, ''De Civitate Dei'' VII 8, who uses the word ''hiatus'' to explain the assimilation of Janus to the world : "Duas eum facies ante et retro habere dicunt, quod hiatus noster, cum os aperimus, mundus similis videatur; unde et palatum Graeci ουρανόν appellant, et nonnulli, inquit, poetae Latini caelum vocaverunt ''palatum'', a quo hiatu oris et fores esse aditum ad dentes versus introrsus ad fauces". Ianus would be the gap (hiatus) through which the sky, represented as the dome of the palate, is manifest: the first meaning of ''palatum'' was sky. Capdeville finds a reminiscence of the same etymology also in [[Valerius Messala]] augur's definition, apud Macrobius  ''Saturnalia'' I 9, 14, that sounds as somehow related to Paulus's: "He who makes and rules everything, keeping together with the force of the allcovering heaven the heavy nature of earth and water collapsing into the deep with the light nature of fire and wind escaping into the boundless high."</ref>
Another etymology proposed by [[Nigidius Figulus]] is related by [[Macrobius]]:<ref>Macrobius above I 9,8.</ref> ''Ianus'' would be [[Apollo]] and [[Diana (mythology)|Diana]] ''Iana'', by the addition of a ''D'' for the sake of euphony. This explanation has been accepted by A. B. Cook and J. G. Frazer. It supports all the assimilations of Janus to the bright sky, the sun and the moon. It supposes a former *Dianus, formed on *dia- < *dy-eð<small>2</small> from the [[Indo-European Languages|Indo-European]] root *dey- shine represented in Latin by ''dies'' day, Diovis and Iuppiter.<ref>A. B. Cook ''Zeus. A Study in Ancient Religion'' Cambridge 1925 II p. 338-9 supposes two parallel series *Divianus, *Dianus, Ianus and Diviana (Varro ''Lingua Latina'' V 68), Diana, Iana (Varro ''De Re Rustica'' I 37, 3). This interpretation encounters the difficulty of the long ''i'' in Dīāna. G. Radke ''Die Götter Altitaliens'' Münster 1965 p. 147.</ref> However the form Dianus postulated by Nigidius is not attested.
A third etymology indicated by [[Cicero]], [[Ovid]] and [[Macrobius]], which explains the name as Latin, deriving it from the verb ''ire'' ("to go") is based on the interpretation of Janus as the god of beginnings and transitions.<ref>Ovid ''Fasti'' I 126-7; Macrobius, ''[[Saturnalia]]'', I, 9, 11: "Alii mundum, id est caelum, esse voluerunt: Ianumque ab eundo dictum, quod mundum semper eat, dum in orbem volvitur et ex se initium faciens in se refertur: unde et Cornificius Etymorum libro tertio: Cicero, inquit, non-Ianum sed Eanum nominat, ab eundo." It should be observed that Cornificius's quotation from Cicero contains a mistake, as Cicero did not name a ''Eanum''; Cicero ''De Natura Deorum'' II 67: "Cumque in omnibus rebus vim habent maxumam prima et extrema, principem in sacrificando Ianum esse voluerunt, quod ab eundo nomen est ductum, ex quo transitiones perviae iani foresque in liminibus profanarum aedium ianuae nominantur"." "As in everything the first and the last things have the greatest force, they wanted that Janus be the first in sacrificial actions, because his name is derived from going, from which fact previous passages are named ''iani'' and the hollows in the boundary of secular houses ''ianuae''."</ref>

[[File:Montfaucon's Janus.jpg|thumb|upright=1.5|Different depictions of Janus from [[Bernard de Montfaucon]]'s ''L'antiquité expliquée et représentée en figures'']]
While the fundamental nature of Janus is debated, in most modern scholars' view the god's functions may be seen as being organized around a single principle: presiding over all beginnings and transitions, whether abstract or concrete, sacred or profane.<ref>Among these: C. Bailey; M. Renard; R. Schilling; G. Dumezil; G. Capdeville.</ref> Interpretations concerning the god's fundamental nature either limit it to this general function or emphasize a concrete or particular aspect of it (identifying him with light,<ref>L.

Bailey, ''Phases in the Religion of Ancient Rome'' (Berkeley, 1932), pp. 46–47: Janus would have developed from the animistic spirit of the door, ''ianua''.</ref> bridges,<ref>L. A.

Grimal, "Le dieu Janus et les origines de Rome", ''Lettres d'humanité'' 4 (1945), pp. 15–121 esp. p. 118.</ref>
Almost all of these modern explanations were originally formulated by the ancients.<ref>R. Schilling above p. 102 cites Lydus ''De Mensibus'' IV 2 who states that according to Varro the Etruscans called him Heaven; Augustine ''De Civitate Dei'' VII 7 identifies him with the world; Longinus and Messala, cited by Lydus above IV 1, with time; Gavius Bassus with air and Hera (apud Lydus above IV 2).</ref>
===God of beginnings and passages===
His function as god of beginnings has been clearly expressed in numerous ancient sources, among them most notably Cicero, Ovid, and Varro.<ref>Varro apud Augustine ''De Civitate Dei'' VII 9: "Penes Ianum sunt prima, penes Iovem summa... Janus rules over the first things, Jupiter over the highest ones. It is thence right that Jupiter be considered the king of everything, because accomplishment has the first place in order of importance (''dignitas'') even though it has the second in order of time".</ref> As a god of motion, Janus looks after passages, causes actions to start and presides over all beginnings. Since movement and change are interconnected, he has a double nature, symbolised in his two-headed image.<ref>M. Renard, "Aspects anciens de Janus et de Junon", ''Revue belge de philologie et d'histoire'' 31/1 (1953), p. 6.</ref> He has under his tutelage the stepping in and out of the door of homes,<ref>C. Bailey above p. 47.</ref> the ''ianua'', which took its name from him,<ref>F. Altheim ''History of Roman Religion'' London 1938 p. 194; V. Basanoff, ''Les dieux des Romains'' (Paris, 1942), p. 18.</ref> and not vice versa.<ref>M. Renard above p. 6 against C. Bailey above p. 47.</ref> Similarly, his tutelage extends to the covered passages named ''iani'' and foremost to the gates of the city, including the cultic gate of the ''{{lang|la|Argiletum}}'', named ''{{lang|la|Ianus Geminus}}'' or ''{{lang|la|Porta Ianualis}}'' from which he protects Rome against the Sabines.<ref>Ovid ''Fasti'' I 257 ff.; on the location of the ''Porta Ianualis'' cf. P. Grimal, "{{lang|fr|Le dieu Janus et les origines de Rome}}", ''Lettres d' humanité''  4 (1945), p. 41; "Le ''Janus'' de l'Argilete", ''Mélanges d'archaeologie et d'histoire'' 64 (1952), pp. 39–58; G. Lugli ''Roma antica. Il centro monumentale'' (Rome, 1946), p. 82ff.; A. Boethius, "Il tempio di Giano in imo Argileto" in ''Symbolae Philologicae Gotoburgenses'' (Gotheborg, 1950) p.23ff.</ref> He is also present at the [[Sororium Tigillum]], where he guards the terminus of the ways into Rome from Latium.<ref>It is possible that the Tigillum was on the boundary of the [[pomerium]], perhaps the eastern gate at the end of the ''decumanus'' of Rome, before the inclusion of the [[Septimontium]]: cf. the repetition of the formula ''vel intra pomerium vel extra pomerium'' in Livy's record concerning the expiation of the Horatius (I 26, 6 and 11): R. Schilling, "Janus. Le dieu introducteur. Le dieu des passages",  ''Mélanges d'archéologie et d'histoire'' 72 (1960), p. 110, citing A. Piganiol in ''MEFR'' (1908), pp. 233–82.</ref> He has an altar, later a temple near the ''[[Porta Carmentalis]]'', where the road leading to [[Veii]] ended, as well as being present on the [[Janiculum]], a gateway from Rome out to Etruria.<ref>Paulus s.v. Ianiculum; L. Audin "Janus, le génie de l'Argilète", ''Lettres d' Humanité'' 10 (1951), pp. 54–5, 59, 71, 73.</ref>
The connection of the notions of beginning (''principium''), movement, transition (''eundo''), and thence time was clearly expressed by Cicero.<ref>C. Bailey, ''Phases in the Religion of Ancient Rome'' (Berkeley, 1932), p. 46; Cicero ''De Natura Deorum'' II 67.</ref> In general, Janus is at the origin of time as the guardian of the gates of Heaven: Jupiter himself can move forth and back because of Janus's working.<ref>Ovid ''Fasti'' I 125–126: "I preside over the gates of Heaven together with the mild Hours: Jupiter himself goes and comes back by my working".</ref> In one of his temples, probably that of [[Forum Holitorium]], the hands of his statue were positioned to signify the number 355 (the number of days in a lunar year), later 365, symbolically expressing his mastership over time.<ref>Pliny ''Naturalis Historia'' XXXIV 7; Macrobius ''Saturnalia'' I 9 10; Lydus ''De Mensibus'' I 4.</ref> He presides over the concrete and abstract beginnings of the world,<ref>According to [[Marcus Terentius Varro|Varro]], in the ''Carmen Saliare'' Janus is called "creator", as the initiator of the world itself. ''De Lingua Latina'', VII, 26–27; Ovid ''Fasti'' I 117-20 states he is the ruler and mover of the universe.</ref> such as religion and the gods themselves,<ref>Macrobius ''Saturnalia'' I 9, 2.</ref> he too holds the access to Heaven and to other gods: this is the reason why men must invoke him first, regardless of the god they want to pray to or placate.<ref>Ovid ''Fasti'' I 173-4.</ref> He is the initiator of human life,<ref>Macrobius defines him ''Consivium'', i.e. propagator of the mankind. ''Saturnalia'', I, 9, 16.</ref> of new historical ages, and financial enterprises: according to myth he was the first to mint coins and the [[As (coin)|as]], first coin of the liberal series, bears his effigy on one face.<ref>Macrobius ''Sat. '' I 7, 22: the ship on the other face remembers the arrival of Saturn; cf. Ovid ''Fasti'' I 230-40.</ref>
===God of change===
Janus frequently symbolized change and transitions such as the progress of past to future, from one condition to another, from one vision to another, and young people's growth to adulthood. He represented time because he could see into the past with one face and into the future with the other.<ref>Macrobius ''Saturnalia'' I 7, 20 and I 9, 4: [[Antevorta]] and [[Postvorta]] or Porrima are his associates deities in this function.  Ovid ''Fasti'' I 133-40 states his double head means he as ''caelestis ianitor aulae'', gatekeeper of the heavenly mansion, can watch both the eastern and western gate of heaven.</ref> Hence, Janus was worshipped at the beginnings of the harvest and planting times, as well as at marriages, deaths and other beginnings. He represented the middle ground between barbarism and civilization, rural and urban space, youth and adulthood. Having jurisdiction over beginnings Janus had an intrinsic association with omens and auspices.<ref>Ovid ''Fasti'' I 178-82:"Omens are in the beginnings, You turn your fearful ears to the first sound and the augur decides on the grounds of the first bird he has seen. The doors of the temples are open as well as the ears of the gods...and the words have weight".</ref>
=== Demi-god or a king reformator ===
[[Plutarch]] in his [[Parallel Lives]] mention that [[Numa Pompilius]] made [[January]] the first month in the calendar instead of [[March]] by the next reason: "he wished in every case that martial influences should yield precedence to civil and political.  For this Janus, in remote antiquity, whether he was a demi-god or a king, was a patron of civil and social order, and is said to have lifted human life out of its bestial and savage state. For this reason he is represented with two faces, implying that he brought men's lives out of one sort and condition into another."<ref>{{cite book |title=Plutarch, The Parallel Lives The Life of Numa |page=373 |edition=Loeb Classical Library 1914 |url=https://penelope.uchicago.edu/Thayer/E/Roman/Texts/Plutarch/Lives/Numa*.html |access-date=20 May 2024}}</ref>
===Position in the pantheon===
[[Leonhard Schmitz]] suggests that he was likely the most important god in the Roman archaic ''pantheon''. He was often invoked together with ''Iuppiter'' (Jupiter).<ref>L. Schmitz s.v. Janus in W. Smith above p. 550-551.</ref>
====Structural peculiarity theory====
{{main|Trifunctional hypothesis}}
In several of his works, [[G. Dumézil]] proposed the existence of a structural difference in level between the [[Proto-Indo-European gods]] of beginning and ending, and the other gods whom Dumézil postulated fall into [[Trifunctional hypothesis|a tripartite structure]], reflecting the most ancient organization of society. So in [[Proto-Indo-European religion|IE religions]] there is an introducer god (such as [[Vedic]] [[Vâyu]] and Roman Janus) and a god of ending, and a nurturer goddess who is often also a fire spirit (such as Roman [[Vesta (mythology)|Vesta]], Vedic [[Saraswati]] and [[Agni]], [[Avestic]] [[Armaiti]] and [[Anahita|Anâitâ]]) who show a sort of mutual solidarity.
The concept of 'god of ending' is defined in connection to the human point of reference, i.e. the current situation of man in the universe, and not to endings as transitions into new circumstances, which are under the jurisdiction of the gods of beginning, owing to the ambivalent nature of the concept. Thus the god of beginning is not structurally reducible to a sovereign god, nor the goddess of ending to any of the three categories on to which Dumézil distributed goddesses. There is though a greater degree of fuzziness concerning the function and role of goddesses, which may have formed a preexisting structure allowing the absorption of the local Mediterranean mother goddesses, nurturers, and protectresses .<ref name=Dumézil-1946>{{cite book |author=Dumézil, G. |author-link=Georges Dumézil |year=1946 |section=De Janus à Vesta |title=Tarpeia |place=Paris, FR |pages=33–113}}</ref><ref>{{cite book |author=Marconi, M. |title=Riflessi mediterranei nella piú antica religione laziale |place=Milan, IT |year=1940}}</ref>
As a consequence, the position of the gods of beginning would not be the issue of a diachronic process of debasement undergone by a supreme sky god, but rather a structural feature inherent to the culture's theology. The descent of primordial sky gods into the condition of ''[[deus otiosus]]'' is a well-known phenomenon in many religions.
Dumézil himself observed and discussed in many of his works the phenomenon of the fall of archaic celestial deities in numerous societies of ethnologic interest.<ref>{{cite book |author=Eliade, M. |author-link=Mircea Eliade |year=1949 |title=Traité d' histoire des religions |place=Paris, FR |page=53}}<br/> {{cite book |author=Eliade, M. |author-link=Mircea Eliade |year=1950 |title=Le chamanisme et les techniques archaiques de l'ecstase |place=Paris, FR |at=ch.&nbsp;VI 1}}</ref>
[[Mircea Eliade]] evaluated Dumezil's views (1946)<ref name=Dumézil-1946/> positively, and recommended their use in comparative research on Indo-European religions.<ref>{{cite journal |author=Eliade, M. |author-link=Mircea Eliade |year=1949 |title=Pour une histoire generale des religions Indo-europeennes |journal=Annales: Économies, Sociétés, Civilisations |volume=4 |issue=2 |pages=183–191, esp. pp. 189–190|doi=10.3406/ahess.1949.1718 |s2cid=161243722 }}</ref>
====Solar god theories====
According to [[Macrobius]] who cites [[Nigidius Figulus]] and [[Cicero]], ''Janus'' and ''Jana'' ([[Diana (mythology)|Diana]]) are a pair of divinities, worshipped as [[Apollo]] or the [[Sol (Roman mythology)|sun]] and [[Luna (mythology)|moon]], whence Janus received sacrifices before all the others, because through him is apparent the way of access to the desired deity.<ref>[[Macrobius]] ''Saturnalia'' I 9, 8–9</ref><ref>[[Cicero]] ''[[De Natura Deorum]]'' ii. 67.</ref>
A similar solar interpretation has been offered by A. Audin who interprets the god as the issue of a long process of development, starting with the [[Sumeric]] cultures, from the two solar pillars located on the eastern side of temples, each of them marking the direction of the rising sun at the dates of the two [[solstices]]: the southeastern corresponding to the Winter and the northeastern to the Summer solstice. These two pillars would be at the origin of the theology of the [[divine twins]], one of whom is mortal (related to the NE pillar, nearest the Northern region where the sun does not shine) and the other is immortal (related to the SE pillar and the Southern region where the sun always shines). Later these iconographic models evolved in the Middle East and Egypt into a single column representing two torsos and finally a single body with two heads looking at opposite directions.<ref>{{cite journal |first=A. |last=Audin |year=1956 |title=Dianus bifrons ou les deux stations solaires, piliers jumeaux et portiques solsticiaux |journal=Revue de géographie de Lyon |volume=31 |issue=3 |pages=191–198|doi=10.3406/geoca.1956.2090 }}</ref>
[[Numa Pompilius|Numa]], in his regulation of the [[Roman calendar]], called the first month ''[[Ianuarius|Januarius]]'' after Janus, according to tradition considered the highest divinity at the time.
== Temples ==
[[File:Sesterce temple janus.JPG|thumb|The temple of Janus with closed doors, on a ''sestertius'' issued under [[Nero]] in 66 AD from the mint at [[Lugdunum]]]]
Numa built the ''[[Temple of Janus (Roman Forum)|Ianus geminus]]'' (also ''Janus Bifrons'', ''Janus Quirinus'' or ''Portae Belli''), a passage ritually opened at times of war, and shut again when Roman arms rested.<ref>Horat. Carm. iv. 15. 8; . Aen. vii. 607</ref> It formed a walled enclosure with gates at each end, situated between the old [[Roman Forum]] and that of Julius Caesar, which had been consecrated by [[Numa Pompilius]] himself. About the exact location and aspect of the temple there has been much debate among scholars.<ref>Cf. V. Müller, "The Shrine of Janus Geminus in Rome", ''American Journal of Archaeology'' 47 (1943), pp. 437–440; P. Grimal, "Le Janus de l' Argilète", ''Mélanges d'archéologie et d'histoire'' 64 (1952), pp. 39–58.</ref> In wartime the gates of the Janus were opened, and in its interior sacrifices and ''vaticinia'' were held, to forecast the outcome of military deeds.<ref>[[Livy]], ''History of Rome'', I, 19, 2;</ref> The doors were closed only during peacetime, an extremely rare event.<ref>[[Livy]] wrote in his ''[[Ab urbe condita]]'' that the doors of the temple had only been closed twice since the reign of Numa: firstly in 235 BC after the [[first Punic war]] and secondly in after the [[battle of Actium]] in 31 BC. Cf. Ovid ''Fasti'' I 121–4; 277–83.</ref> The function of the Ianus Geminus was supposed to be a sort of good omen: in time of peace it was said to close the wars within or to keep peace inside;{{Which|date=March 2012}} in times of war it was said to be open to allow the return of the people on duty.<ref>Ovid above I 279–280; Virgil above.</ref>
A temple of Janus is said to have been consecrated by the consul [[Gaius Duilius]] in 260 BC after the [[battle of Milazzo (260 BC)|Battle of Mylae]] in the [[Forum Holitorium]]. It contained a statue of the god with the right hand showing the number 300 and the left the number 65—i.e., the length in days of the solar year, and twelve altars, one for each month.<ref>Pliny ''Naturalis Historia'' XXXIV 33; Macrobius ''Saturnalia'' I 9 10; Varro apud Macrobius above I 9 16. R. Schilling above p. 115 remarks such a feature could have been added only after the Julian reform of the calendar.</ref>
The four-sided structure known as the [[Arch of Janus]] in the [[Forum of Nerva|Forum Transitorium]] dates from the 1st century of the Christian era: according to common opinion it was built by the Emperor [[Domitian]]. However American scholars L. Ross Taylor and L. Adams Holland on the grounds of a passage of [[Statius]]<ref>''Silvae'' IV 3, 9–10: "... qui limina bellicosa Iani/ iustis legibus et foro coronat", "... who crowns the warlike boundaries of Janus with just laws and the Forum".</ref> maintain that it was an earlier structure (tradition has it the ''Ianus Quadrifrons'' was brought to Rome from [[Falerii]]<ref>Macrobius I 9, 13; Servius ''Aen.'' VI 607; Lydus ''De Menisibus'' IV 1.</ref>) and that Domitian only surrounded it with his new forum.<ref>L. Adams Holland, "Janus and the Fasti", ''Classical Philology'' (1952), p. 139.</ref> In fact the building of the Forum Transitorium was completed and inaugurated by [[Nerva]] in AD 96.
== Cult epithets ==
Another way of investigating the complex nature of Janus is by systematically analysing his cultic epithets: religious documents may preserve a notion of a deity's theology more accurately than other literary sources.
The main sources of Janus's cult epithets are the fragments of the [[Carmen Saliare]] preserved by Varro in his work [[De Lingua Latina]], a list preserved in a passage of [[Macrobius]]'s [[Saturnalia]] (I 9, 15–16), another in a passage of [[Johannes Lydus]]'s [[De Mensibus]] (IV 1), a list in [[Cedrenus]]'s ''Historiarum Compendium'' (I p.&nbsp;295 7 Bonn), partly dependent on Lydus's, and one in [[Servius Honoratus]]'s commentary to the ''Aeneis'' (VII 610).<ref>G Capdeville above p. 404-7.</ref> Literary works also preserve some of Janus's cult epithets, such as [[Ovid]]'s long passage of the ''[[Fasti (poem)|Fasti]]'' devoted to Janus at the beginning of Book I (89–293), [[Tertullian]], [[Augustine]] and [[Arnobius]].
=== Carmen Saliare ===
As may be expected the opening verses of the Carmen,<ref>Varro ''Lingua Latina'' VII 26 and 27.</ref> are devoted to honouring Janus, thence were named ''{{lang|la|versus ianuli}}''.<ref>This does not mean that there was any particular link between the [[Salii]] and Janus, contrary to what Lydus states in ''{{lang|la|De Mensibus}}'' IV 2, i. e. that the Salii were consecrated to the cult of Janus. R. G. Kent in the Loeb edition of Varro's ''{{lang|la|De Lingua Latina}}'' 1938 p. 293 n. e states these verses were addressed to Mars.</ref> Paul the Deacon<ref>Paulus Festi epitome s.v. ''{{lang|la|axamenta}}''  p.&nbsp;3 L.</ref> mentions the ''{{lang|la|versus ianuli, iovii, iunonii, minervii}}''. Only part of the ''{{lang|la|versus ianuli}}'' and two of the ''{{lang|la|iovii}}'' are preserved.
The manuscript has:
:(paragraph 26): "''{{lang|la|cozeulodorieso. omia ũo adpatula coemisse./ ian cusianes duonus ceruses. dun; ianusue uet põmelios eum recum}}''";
:(paragraph 27): "''{{lang|la|diuum êpta cante diuum deo supplicante}}.''" "''{{lang|la|ianitos}}''".
Many reconstructions have been proposed:<ref>References in A.B. Cook above II p.&nbsp;329–331; a later attempt by J. F. K. Dirichs ''Die urlateinischen Reklamestrophe auf dem sogenannten Dresselschen Drillingsgefäss des sabinischen Töpfers Dufnos'' Heidelberg 1934 p.&nbsp;30.</ref>
they vary widely in dubious points and are all tentative, nonetheless one can identify with certainty some epithets:
* ''Cozeiuod''<ref>Restoring ''i'' for ''l'': this reading is accepted by both Havet and Dirichs above.</ref> ''orieso.''<ref>The interpretation "Cozeiuod orieso"&nbsp;=&nbsp;"Conseuiod orieso" is Dirich's. Havet reads: "{{lang|la|Cozeui adoriose}}"&nbsp;=&nbsp;"{{lang|la|Conseui gloriose}}" on the grounds of Paulus's glossa s.v. ''adoria'': "praise, glory deriving from the abundance of spelt (far)" p.&nbsp;3, 22 L.</ref> ''{{lang|la|Omnia vortitod}}''<ref>Capdeville follows L. Havet reading a future imperative of ''vorto''; cf. Ovid ''Fasti''&nbsp;I pp.&nbsp;119–120: "{{lang|la|Me penes est unum vasti custodia mundi,/ et ius vertendi cardinis omne meum est}}", "It is only my own power the tutelage of the vast universe,/ and the right of turning its hinge is all mine".</ref> ''{{lang|la|Patulti; oenus es}}''
* ''{{lang|la|iancus}}'' (or ''{{lang|la|ianeus}}''), ''Iane, es, duonus Cerus es, duonus Ianus.''
* ''{{lang|la|Veniet potissimum melios eum recum}}.''
* ''{{lang|la|Diuum eum patrem}}'' (or ''{{lang|la|partem}}'') ''{{lang|la|cante, diuum deo supplicate}}.''
* ''{{lang|la|ianitos}}.''<ref>G Capdeville above p.&nbsp;405–406, following in part L. Havet "{{lang|la|De Saturnio Latinorum versu}}" in ''BEPHE'' '''43''' Paris 1880 p.&nbsp;243–251. "Let it begin from/with the Sower. Make everything turn, Patultius, Thou are the one/ Gatekeeper, Janus, are Thou, good creator are Thou, good Janus./ Let Him come, the most powerful of all kings./ Sing Him the father (or part) of the gods, beseech the god of the gods./ Gatekeeper.</ref>
The epithets that can be identified are:
; ''Cozeuios'': i.e. ''{{lang|la|Conseuius}}'' the Sower, which opens the carmen and is attested as an old form of ''Consivius'' in [[Tertullian]];<ref>''Ad Nationes''&nbsp;II 11, 3.  Cozeuiod, ablative case of Cozeuios, would be an archaic spelling of {{lang|la|Consēuius}}: -ns> -nts>  -ts>  -z. Cf.&nbsp;[[Velius Longus]] ''Orthographia''&nbsp;8 p.&nbsp;50, 9 and 51, 5th&nbsp;ed. Keil on the use of letter  ''z'' in the carmen Saliare.</ref>
; ''{{lang|la|Patultius}}'': the Opener;
; ''{{lang|la|Iancus}}'' or ''{{lang|la|Ianeus}}'': the Gatekeeper;
; ''{{lang|la|Duonus Cerus}}'': the Good Creator;
; ''rex'': king ({{lang|la|potissimum melios eum recum}} – the most powerful and best of kings);
; ''{{lang|la|diuum patrem (partem) }}'':<ref>Festus s.v. ''pa'' p.&nbsp;222L: "{{lang|la|pa pro parte, po pro potissimum in Saliari carmine positum est}}": the correction ''{{lang|la|patre}}'' for ''{{lang|la|parte}}'' is allowed by Müller, by not by Lindsay.</ref> father of the gods (or part of the gods);
; ''{{lang|la|diuum deus}}'': god of the gods;
; ''{{lang|la|ianitos}}'': keeping track of time, Gatekeeper.
=== Other sources ===
The above-mentioned sources give: ''Ianus Geminus, I. Pater, I. Iunonius, I. Consivius, I. Quirinus, I. Patulcius and Clusivius'' (Macrobius above I 9, 15): Ι. Κονσίβιον, Ι. Κήνουλον, Ι. Κιβουλλιον, I. Πατρίκιον, I. Κλουσίβιον, I. Ιουνώνιον, I. Κυρινον, I. Πατούλκιον, I. Κλούσιον, I. Κουριάτιον (Lydus above IV 1); I. Κιβούλλιον, I. Κυρινον, I. Κονσαιον, I. Πατρίκιον (Cedrenus ''Historiarum Compendium'' I p.&nbsp;295 7 Bonn); ''I. Clusiuius, I. Patulcius, I. Iunonius, I. Quirinus'' (Servius ''Aen.'' VII 610).
Even though the lists overlap to a certain extent (five epithets are common to Macrobius's and Lydus's list), the explanations of the epithets differ remarkably. Macrobius's list and explanation are probably based directly on [[Cornelius Labeo]]'s work, as he cites this author often in his ''Saturnalia'', as when he gives a list of [[Maia (mythology)|Maia]]'s cult epithets<ref>Macrobius above I 12, 21–22.</ref> and mentions one of his works, ''Fasti''.<ref>Macrobius above I 16, 29.</ref> In relating Janus' epithets Macrobius states: "We invoke in the sacred rites". Labeo himself, as it is stated in the passage on Maia, read them in the lists of [[indigitamenta]] of the [[libri pontificum]]. On the other hand, Lydus's authority cannot have consulted these documents precisely because he offers different (and sometimes bizarre) explanations for the common epithets: it seems likely he received a list with no interpretations appended and his interpretations are only his own.<ref>Capdeville above p. 409.</ref>
====Pater====
''Pater'' is perhaps the most frequent epithet of Janus, found also in the composition ''Ianuspater''. While numerous gods share this cultic epithet it seems the Romans felt it was typically pertinent to Janus.<ref>[[Atheneus]] ''Deipnosophistes'' 15, 692d: Masurius says: "The god Janus is considered among ourselves also as our father."</ref> When invoked along with other gods, usually only he is called pater.<ref>Virgil ''Aen.'' VIII 357: "Hanc Ianus Pater , hanc Saturnus condidit arcem"; Horace ''Epistulae'' I 16, 59: " "Iane pater" clare, clare cum dixit "Apollo" "; Seneca ''Apolocyntosis''IX 2: "primus interrogatur sententiam Ianus pater"; Arnobius ''Ad Nationes'' III 29: "Incipiamus ...sollemniter ab Iano et nos patre".</ref> For Janus the title is not just a term of respect; principally it marks his primordial role. He is the first of the gods and thus their father: the formula ''quasi deorum deum'' corresponds to ''diuum deus'' of the carmen Saliare.<ref>Macrobius above I 9, 14.</ref> Similarly, in the expression ''duonus Cerus'', Cerus means creator and is considered a masculine form related to [[Ceres (Roman mythology)|Ceres]].<ref>Paulus p. 109L; Probus ''In Vergilii Gergicae'' I 7; Servius ibidem.</ref>
Lydus gives Πατρίκιος (Patricius) and explains it as ''autóchthon'': since he does not give another epithet corresponding to Pater it may be inferred that Lydus understands Patricius as a synonym of Pater.<ref>Cf. Lydus ''Mag.'' I 16 p. 20, 24 W on Romulus and the patres called patricii, considered equivalent to ευπατρίδας ; similar confusion in other Greek authors as Plutarch ''Romulus'' XIII 2 and 3; Zonaras ''Histor.'' VII 3.</ref> There is no evidence connecting Janus to gentilician cults or identifying him as a national god particularly venerated by the oldest patrician families.<ref>This hypothesis is advanced by L. Preller- H. Jordan ''Römische Mythologie'' Berlin 1881 2nd p. 171.</ref>
====Geminus====
''Geminus'' is the first epithet in Macrobius's list. Although the etymology of the word is unclear,<ref>A. Ernout- A. Meillet ''Dict. Etym. de la langue latine'' 4th ed. s.v. p. 268–9.</ref> it is certainly related to his most typical character, that of having two faces or heads. The proof are the numerous equivalent expressions.<ref>''bifrons'' (Vergil ''Aeneis'' VII 180; XII 198; Servius ''Aen.'' VII 607; Ausonius ''Eclogae'' X 2; ''Dom''. VI 5; Prudentius ''Sym.'' I 233; Macrobius ''Saturnalia'' I 9, 4 and 13; Augustine ''De Civ. Dei'' VII 7,8 Isidorus ''Origines'' V 33, 3); ''biceps'' (Ovid ''Fasti'' I 65; ''Pontica'' IV 4, 23); ''anceps'' (Ovid ''Metamorphoses'' XIV 334; ''Fasti'' I 95); ''biformis'' (Ovid ''Fasti'' I 89; V 424).</ref> The origin of this epithet might be either concrete, referring directly to the image of the god reproduced on coins<ref>Pliny above XXXIV 45; Plutarch ''Quaestiones Romanae'' 41, 274 e; Atheneus XV 692 e. For Italian coins cf.  E. A. Sydenham ''The coinage of the Roman Republic'' London 1952 no. 8 p. 2 and plate 4 etc.</ref> and supposed to have been introduced by king [[Numa Pompilius|Numa]] in the sanctuary at the lowest point of the Argiletum,<ref>Livy I 19, 2; Pliny ''Naturalis Historia'' XXXIV 33; Servius ''Ad Aen.'' VII 607.</ref> or to a feature of the Ianus of the ''Porta Belli'', the double gate ritually opened at the beginning of wars,<ref>Cf. Vergil ''Aen.'' VII 607 on the analogous monument in the town of [[Latinus]].</ref> or abstract, deriving metaphorically from the liminal, intermediary functions of the god themselves: both in time and space passages connected two different spheres, realms or worlds.<ref>Ovid ''Fasti'' I 73–4; Macrobius above I 9, 9; Servius ''Ad Aen.'' VII 610; Lydus above IV 2 p. 65, 7 Wünsch.</ref> The ''Janus quadrifrons'' or ''quadriformis'', brought according to tradition from Falerii in 241 BC<ref>Servius ''Ad Aen.'' VII 607; Macrobius ''Sat.'' I 9, 13; Augustin ''Civ. Dei'' VII 4, 8; Isidorus ''Origines'' VIII 11, 23.</ref> and installed by Domitian in the [[Forum of Nerva|Forum Transitorium]],<ref>Lydus above IV 1 p. 64, 4 W.</ref> although having a different meaning, seems to be connected to the same theological complex, as its image purports an ability to rule over every direction, element and time of the year. It did not give rise to a new epithet though.<ref>Macrobius above; Lydus above; Augustine above VII 8; VII 4.</ref><ref>R. Pettazzoni above p. 89: "A naïve iconographic expression of watching into the two opposite directions and thence, ideally, into every direction".</ref>
====Patulcius and Clusivius the 1st====
''Patulcius'' and ''Clusivius'' or ''Clusius'' are epithets related to an inherent quality and function of doors, that of standing open or shut. Janus as the Gatekeeper has jurisdiction over every kind of door and passage and the power of opening or closing them.<ref>Ovid above I 117-8: "Quidquid ubique vides, caelum, mare, nubila, terras,/ omnia sunt nostra clausa patentque manu".</ref> Servius interprets Patulcius in the same way. Lydus gives an incorrect translation, "αντί του οδαιον" which however reflects one of the attributes of the god, that of being the protector of roads.<ref>Macrobius above I 9, 7 considers this to be an attribute of Janus as gatekeeper: "...cum clavi et virga figuratus , quasi omnium portarum custos et rector viarum".</ref> Elsewhere Lydus cites the epithet θυρέος to justify the key held by Janus.<ref>Lydus above p. 64, 2 W.</ref> The antithetical quality of the two epithets is meant to refer to the alterning opposite conditions<ref>Ovid above I 131-2: "...nomina diversas significare vices".</ref> and is commonly found in the ''indigitamenta'': in relation to Janus, Macrobius cites instances of [[Antevorta]] and [[Postvorta]],<ref>Macrobius above I 7, 21.</ref> the personifications of two indigitations of [[Carmentis]].<ref>Varro apud Gellius ''Noctes Atticae'' XVI 16, 4 in the form [[Antevorta|Porrima]]; L. L. Tels De Jong ''Sur quelques divinités romaines de la naissance et de la prophétie'' Leyden Delft 1959 p. 41-60. Another instance of opposite epithets in the indigitamenta is that of [[Empanda|Panda]] and Cela, referring to [[Ceres (Roman mythology)|Ceres]]. Cf. J. Bayet " "Feriae Sementiuae" et les Indigitations dans le culte de Ceres et de Tellus" in ''Revue de l'histoiire des religions'' '''137''' 1950 p. 172-206 part. p.195-197.</ref>
These epithets are associated with the ritual function of Janus in the opening of the ''{{lang|la|Porta Ianualis}}'' or ''Porta Belli''.<ref>Varro ''Lingua Latina'' V 165: Livy I 19, 2; Pliny ''Naturalis Historia'' XXXIV 33.</ref> The rite might go back to times pre-dating the founding of Rome.<ref>Cf. Vergil ''Aeneis'' VII 601–615.</ref> Poets tried to explain this rite by imagining that the gate closed either war or peace inside the ''ianus'', but in its religious significance it might have been meant to propitiate the return home of the victorious soldiers.<ref>Ovid above I 279-80; Servius ''Aen.'' I 291; Lydus IV 2 p. 65,17 W.; G. Capdeville above p. 420</ref>
====Quirinus====
''Quirinus'' is a debated epithet. According to some scholars, mostly Francophone, it looks to be strictly related to the ideas of the passage of the Roman people from war back to peace, from the condition of ''miles'', soldier, to that of ''quiris'', citizen occupied in peaceful business, as the rites of the ''Porta Belli'' imply. This is in fact the usual sense of the word ''quirites'' in Latin.<ref>G . Dumézil ''La religion romaine archaïque '' Paris 1966 above p. 246-271; R. Schilling "Janus. Le dieu introducteur. Le dieu des passages" in ''Melanges d'archeologie et d'histoire'' '''72''' 1960 p.119-120 citing G. Wissowa ''Religion und Kultus der Römer'' Munich 1912 p. 109; Paulus p. 43 L: "Romani a Quirino Quirites dicuntur"; Festus p. 304L: "... Quirites dicti, post foedus a Romulo et Tatio percussum, communionem et societatem populi factam indicant"." ... are named Quirites after the community and society created because of the treaty made by Tatius and Romulus".</ref> Other scholars, mainly Germanophone, think it is related on the contrary to the martial character of the god Quirinus, an interpretation supported by numerous ancient sources: Lydus,<ref>Lydus above: "πρόμαχος".</ref> Cedrenus,<ref>Cedrenus, above.</ref> Macrobius,<ref>Macrobius above I 9, 16: "Quirinus quasi bellorum potentem, ab hasta quam Sabini ''curin'' vocant".</ref> Ovid,<ref>Ovid above II 475–478.</ref> Plutarch<ref>Plutarch ''Romulus'' XXIX 1; ''Quaestiones Romanae'' XXVII 285 cd.</ref> and Paul the Daecon.<ref>Paulus 43, 1 L.</ref><ref>L. Deubner ''Mitteilungen des deutschen archaeologisches Institut'' Berlin '''36–37''' 1921–1922 p. 14 ff.; W. F. Otto ''Pauly Real Enzyklopaedie der Altertumswissenschaften'' Supplem. III col. 1182.</ref>
Schilling and Capdeville counter that it is his function of presiding over the return to peace that gave Janus this epithet, as confirmed by his association on 30 March with [[Pax (mythology)|Pax]], [[Concordia (mythology)|Concordia]] and [[Salus]],<ref>Ovid above III 881–882; J.- C. Richard "Pax, Concordia et la religion officielle de Janus à la fin de la République romaine'' in ''MEFR'' '''75''' 1963 p. 303-386.</ref> even though it is true that Janus as god of all beginnings presides also over that of war and is thus often called ''belliger'', bringer of war<ref>[[Lucan]] ''Pharsalia'' I 61-2; [[Statius]] ''Silvae'' II 3, 12.</ref> as well as ''pacificus''. This use is also discussed by Dumézil in various works concerning the armed nature of the ''Mars qui praeest paci'', the armed quality of the gods of the third function and the arms of the third function.<ref>G. Dumézil "Remarques sur les armes des dieux de la troisième fonction chez divers peuples indo-européens" in ''Studi e Materiali di Storia delle Religioni''  '''28''' 1957 p. 1-10.</ref>
Koch on the other hand sees the epithet Janus Quirinus as a reflection of the god's patronage over the two months beginning and ending the year, after their addition by king Numa in his reform of the calendar. This interpretation too would befit the liminal nature of Janus.<ref>C. Koch "Bemerkungen zum römischen Quirinuskult" in ''Zeitschrift für Religions and Geistesgeschichte'' 1953 p.1-25.</ref>
The compound term ''Ianus Quirinus'' was particularly in vogue at the time of Augustus, its peaceful interpretation complying particularly well with the Augustan ideology of the ''Pax Romana''.<ref>Res Gestae Divi Augusti XIII; [[Suetonius]] ''Augustus'' XXII 5; [[Horace|Horatius]] ''Odes'' IV 15, 4–9.</ref>
The compound ''Ianus Quirinus'' is to be found also in the rite of the [[spolia opima]], a ''lex regia'' ascribed to Numa, which prescribed that the third rank spoils of a king or chief killed in battle, those conquered by a common soldier, be consecrated to ''Ianus Quirinus''.<ref>Only Festus s. v. p. 204, 13 L, among the three sources relating this rite has the expression ''Ianui Quirino''; Plutarch ''Marcellus'' VIII 9 and Servius (and Virgil himself) ''Aeneis'' VI 859 have only Quirinus. This has led to disputes among scholars on the value of the expression and its antiquity as [[Verrius Flaccus]] may have forged it.</ref> Schilling believes the reference of this rite to Ianus Quirinus to embody the original prophetic interpretation, which ascribes to this deity the last and conclusive spoils of Roman history.<ref>R. Schilling above p.128, citing Festus s. v. spolia opima p. 204 L.</ref>
====Ποπάνων (Popanon, Libo?)====
The epithet ''Ποπάνων (Popanōn)'' is attested only by Lydus,<ref>Lydus above IV 2 p. 64, 18 W.</ref> who cites Varro as stating that on the day of the [[kalendae]] he was offered a cake which earned him this title. There is no surviving evidence of this name in Latin, although the rite is attested by Ovid for the kalendae of January<ref>Ovid above I 128: "libum farraque mixta sale".</ref> and by Paul.<ref>Paulus s.v. Ianual p. 93, 4 L.</ref> This cake was named ''{{lang|la|ianual}}'' but the related epithet of Janus could not plausibly have been Ianualis: it has been suggested ''Libo''<ref>J. Speÿer above p. 28.</ref> which remains purely hypothetical. The context could allow an Etruscan etymology.
====Iunonius====
Janus owes the epithet ''Iunonius'' to his function as patron of all kalends, which are also associated with Juno. In Macrobius's explanation: "''Iunonium, as it were, not only does he hold the entry to January, but to all the months: indeed all the kalends are under the jurisdiction of Juno''". At the time when the rising of the new moon was observed by the [[pontifex]] minor the [[rex sacrorum]] assisted by him offered a sacrifice to Janus in the ''[[Curia Calabra]]'' while the [[regina sacrorum]] sacrificed to Juno in the [[regia]].<ref>Macrobius I 15, 9–10 and 19.</ref>
Some scholars have maintained that Juno was the primitive paredra of the god. This point bears on the nature of Janus and Juno and is at the core of an important dispute: was Janus a debased ancient uranic supreme god, or were Janus and Jupiter co-existent, their distinct identities structurally inherent to their original theology?
Among Francophone scholars, Grimal and (implicitly and partially) Renard and Basanoff have supported the view of a uranic supreme god against Dumézil and Schilling. Among Anglophone scholars Frazer and Cook have suggested an interpretation of Janus as uranic supreme god.
Whatever the case, it is certain that Janus and Juno show a peculiar reciprocal affinity: while Janus is ''Iunonius'', Juno is ''Ianualis'', as she presides over childbirth and the menstrual cycle, and opens doors.<ref>Servius ''Aeneis'' VII 620–622; Ovid ''Fasti'' I ; Isidore ''Origines'' VIII 11, 69: "Iunonem dicunt quasi Ianonem, id est ianuam, pro purgationibus feminarum, eo quod quasi portas matrum natis pandat, et nubentum maritis".</ref> Moreover, besides the kalends Janus and Juno are also associated at the rite of the Tigillum Sororium of 1 October, in which they bear the epithets ''Ianus Curiatius'' and ''Iuno Sororia''. These epithets, which swap the functional qualities of the gods, are the most remarkable apparent proof of their proximity.<ref>M.Renard above p. 14-17.</ref> The rite is discussed in detail in the section below.
====Consivius====
''Consivius'', sower, is an epithet that reflects the tutelary function of the god at the first instant of human life and of life in general, conception. This function is a particular case of his function of patron of beginnings. As far as man is concerned it is obviously of the greatest importance, even though both Augustine and some modern scholars see it as minor.<ref>G. Capdeville above p. 432.</ref> Augustine shows astonishment at the fact that some of the [[Di selecti|dii selecti]] may be engaged in such tasks: "''In fact Janus himself first, when pregnancy is conceived, ... opens the way to receiving the semen''".<ref>Augustine above VII 2.</ref>
Varro on the other hand had clear the relevance of the function of starting a new life by opening the way to the semen and therefore started his enumeration of the gods with Janus, following the pattern of the Carmen Saliare.<ref>Augustine above VI 9: "Thus the same Varro starts mentioning and listing the gods from the conception of man, who have been given life from Janus"; VII 3: "... it is answered that Janus has in his power every start and therefore not without cause is he ascribed that of the opening to conception".</ref> Macrobius gives the same interpretation of the epithet in his list: "''Consivius from sowing (conserendo), i. e. from the propagation of the human genre, that is disseminated by the working of Janus''."<ref>The etymology from ''sero'', albeit clear, presents a problem with the long first ''ī'' of Consīvius: this difficulty can be overcome if one considers {{lang|la|Consēuius}}, attested by [[Tertullian]] ''Ad Nationes'' II 11, 3.</ref> as the most ancient form. He though does not consider ''{{lang|la|Conseuius}}'' to be an epithet of Janus but a theonym in its own right.
Lydus understands {{lang|la|Consivius}} as βουλαιον ({{lang|la|consiliarius}}) owing to a conflation with [[Consus]] through [[Ops]] Consiva or Consivia. The interpretation of Consus as god of advice is already present in Latin authors<ref>Paulus p. 36, 19 L; Tertullian ''De Spectaculis'' V 5; Arnobius ''Adversus Nationes'' III 23; Ausonius ''Eclogae''  XXIV 20; Servius ''Aeneis'' VIII 636; Augustine above IV 11.</ref> and is due to a folk etymology supported by the story of the abduction of the Sabine women, (which happened on the day of the [[Consualia]] aestiva), said to have been advised by Consus. However no Latin source cites relationships of any kind between Consus and Janus Consivius. Moreover, both the passages that this etymology requires present difficulties, particularly as it seems Consus cannot be etymologically related to adjective ''{{lang|la|consivius}}'' or ''{{lang|la|conseuius}}'', found in Ops Consivia and thence the implied notion of sowing.<ref>G. Capdeville above p. 434. Consus is a ''u'' theme word and the only adjective it formed is Consualia.</ref>
====Κήνουλος (Coenulus)====
''Κήνουλος ({{lang|grc-Latn|Coenulus}}) ''and ''Κιβουλλιος ({{lang|grc-Latn|Cibullius}})'' are not attested by Latin sources. The second epithet is not to be found in Lydus's manuscripts and is present in Cedrenus along with its explanation concerning food and nurture. The editor of Lydus R. Wünsch has added Cedrenus's passage after Lydus's own explanation of Coenulus as ευωχιαστικός, good host at a banquet. Capdeville considers Cedrenus' text to be due to a paleographic error: only ''Coenulus'' is indubitably an epithet of Janus and the adjective used to explain it, meaning to present and to treat well at dinner, was used in a ritual invocation before meals, wishing the diners to make good flesh.<ref>G. Capdeville above p. 435.</ref> This is one of the features of Janus as shown by the myth that associates him with Carna, [[Cardea]], Crane.<ref>See below section on myths.</ref>
====Curiatius====
The epithet ''Curiatius'' is found in association with ''Iuno Sororia'' as designating the deity to which one of the two altars behind the Tigillum Sororium was dedicated. [[Sextus Pompeius Festus|Festus]] and other ancient authors<ref>W. Otto ''Real Encyclopaedie'' Suppl. III column 1178-9; Festus s.v. Sororium tigillum p. 380, 5 L.; Dionysius of Halicarnassus ''Antiquitates Romanae'' III 22, 7–9; Scholiasta Bobiensis in Ciceronem ''Milo'' 7.</ref> explain Curiatius by the aetiological legend of the Tigillum: the expiation undergone by P. Horatius after his victory over the Alban [[Curiatii]] for the murder of his own sister, by walking under a beam with his head veiled.<ref>Livy I 26, 13; Paulus ex Festus p.399, 2 L ; Pseudo Aurelius Victor ''Vir.'' 4.</ref>
Capdeville sees this epithet as related exclusively to the characters of the legend and the rite itself: He cites the analysis by Dumézil as his authority.<ref>G. Dumézil ''Les Horaces et les Curiaces'' Paris 1942.</ref>
Schilling supposes it was probably a ''{{lang|la|sacrum}}'' originally entrusted to the ''{{lang|la|gens Horatia}}'' that allowed the desacralisation of the ''{{lang|la|iuvenes}}'' at the end of the military season, later transferred to the state.<ref>Livy I 26, 12: ''... pecunia publica'' ''at public expenses''.</ref> Janus's patronage of a rite of passage would be natural. The presence of Juno would be related to the date (Kalends), her protection of the ''{{lang|la|iuvenes}}'', soldiers, or the legend itself.
Schilling's opinion is that it is related to ''[[curia]]'',<ref>R. Schilling "Janus, dieu introducteur, dieu des passages" in ''Melanges d' archeologie et d'histoire'' '''72''' 1960 p. 109.</ref> as the Tigillum was located not far from the ''{{lang|la|curiae veteres}}''.
Renard considered Schilling's interpretation unacceptable, even though supported by an inscription (''{{lang|la|lictor curiatius}}'')<ref>R. Schilling above citing ''Real Encyclopaedie'' s.v. calata comitia column 1330. Aulus Gellius ''Noctes Atticae'' XV 27, 2 has ''lictor curiatus''.</ref> because of the different quantity of the ''u'', short in ''{{lang|la|curiatius}}'', ''{{lang|la|curis}}'' and ''{{lang|la|Curitis}}'' and long in ''{{lang|la|curia}}''. Moreover, it is part of the different interpretation of the meaning of the ritual of the Tigillum Sororium proposed by Herbert Jennings Rose, Kurt Latte, and Robert Schilling himself.
Renard connects the epithet's meaning to the ''{{lang|la|curis}}'' or ''{{lang|la|cuiris}}'', the spear of Juno Curitis as here she is given the epithet of ''Sororia'', corresponding to the usual epithet ''Geminus'' of Janus and to the twin or feminine nature of the passage between two coupled posts.<ref>M. Renard above p. 14.</ref>
In summary, the etymology of ''Curiatius'' remains uncertain.<ref>For a thorough listing of the hypotheses advanced cf. A. Walde – J. B. Hoffmann ''Lateinische etymologisches Wörterbuch'' 1938 3rd p. 319 s.v.</ref><ref>On the role of Janus in the rite of the Tigillum Sororium see also the section that follows.</ref>
== Rites ==
The rites concerning Janus were numerous. Owing to the versatile and far reaching character of his basic function marking all beginnings and transitions, his presence was ubiquitous and fragmented. Apart from the rites solemnizing the beginning of the new year and of every month, there were the special times of the year which marked the beginning and closing of the military season, in March and October respectively. These included the rite of the ''arma movēre'' on 1 March and that of the ''arma condĕre'' at the end of the month performed by the [[Salii]], and the ''Tigillum Sororium'' on 1 October. Janus Quirinus was closely associated with the anniversaries of the dedications of the temples of Mars on 1 June (a date that corresponded with the festival of [[Cardea|Carna]], a deity associated with Janus: see below) and of that of Quirinus on 29 June (which was the last day of the month in the pre-Julian calendar). These important rites are discussed in detail below.
Any rite or religious act whatsoever required the invocation of Janus first, with a corresponding invocation to [[Vesta (mythology)|Vesta]] at the end (''Janus primus'' and ''Vesta extrema''). Instances are to be found in the ''Carmen Saliare'', the formula of the [[devotio]],<ref>Livy VIII 9, 6</ref> the lustration of the fields and the sacrifice of the ''porca praecidanea'',<ref>Cato ''De Agri Cultura'' 141 and 143.</ref> the ''Acta'' of the [[Arval Brethren]].<ref>''Acta Fratrum Arvalium'' ed. Henze p. CCXIV and 144 ff.</ref>
Although Janus had no [[flamen]], he was closely associated with the [[rex sacrorum]] who performed his sacrifices and took part in most of his rites: the ''rex'' held the first place in the [[ordo sacerdotum]], hierarchy of priests.<ref>Some scholars opine that the rex was Janus's priest, e.g. M. Renard "Aspects anciens de Jaanus et de Junon" in ''Revue belge de philologie et d' histoire'' '''31''' 1. 1953 p. 8. G. Dumézil disagrees as he considers the rex also and even more directly associated with Jupiter.</ref> The flamen of [[Portunus (mythology)|Portunus]] performed the ritual greasing of the spear of the god Quirinus on 17 August, day of the [[Portunalia]], on the same date that the temple of Janus in the [[Forum Holitorium]] had been consecrated by consul [[Gaius Duilius]] in 260 BC.<ref>Portunus seems to be a god closely related to Janus, if with a specifically restricted area of competence, in that he presides over doorways and harbours and shares with Janus his two symbols, the key and the stick: Scholiasta Veronensis ''Aen.'' V 241: "god of harbours and patron of doors". See also section below.</ref>
=== Beginning of the year ===
The winter solstice was thought to occur on 25 December. On 1 January was [[New Year's Day]]: the day was consecrated to Janus since it was the first of the new year and of the month (kalends) of Janus: the ''feria'' had an augural character as Romans believed the beginning of anything was an [[omen]] for the whole. Thus on that day it was customary to exchange cheerful words of good wishes.<ref>Ovid ''Fasti'' I 178–182.</ref> For the same reason everybody devoted a short time to his usual business,<ref>Ovid above 166–170.</ref> exchanged dates, figs and honey as a token of well wishing and made gifts of coins called ''strenae''.<ref>Ovid above 187–190; Pliny ''Naturalis Historia'' XXIII 3, 13; Martial VIII 33; XIII 27.</ref> Cakes made of spelt (''far'') and salt were offered to the god and burnt on the altar.<ref>Ovid ''Fasti'' I 127-8.</ref><ref>L. Schmitz in W. Smith ''Dictionary of Greek and Roman Biography and Mythology'' s.v. Ianus II p. 550-552 London 1890.</ref> Ovid states that in most ancient times there were no animal sacrifices and gods were propitiated with offerings of spelt and pure salt.<ref>Ovid ''Fasti'' I 337-8.</ref> This ''{{lang|la|libum}}'' was named ''{{lang|la|ianual}}'' and it was probably correspondent to the ''summanal'' offered the day before the Summer solstice to god [[Summanus]], which however was sweet being made with flour, honey and milk.
[[File:Ianus ianuarius.jpg|thumb|The month of January is named after Janus]]
Shortly afterwards, on 9 January, on the ''{{lang|la|feria}}'' of the [[Agonium]] of January, the [[rex sacrorum]] offered the sacrifice of a ram to Janus.<ref>Ovid above 334.</ref>
=== Beginning of the month ===
At the kalends of each month, the {{lang|la|rex sacrorum}} and the pontifex minor offered a sacrifice to Janus in the curia Calabra, while the regina offered a sow or a she lamb to Juno.<ref>Macrobius ''Saturnalia'' I 15, 19.</ref>
=== Beginning of the day ===
Morning belonged to Janus: men started their daily activities and business. Horace calls him ''Matutine Pater'', morning father.<ref>Horace ''Sermones'' II 6, 20–23:"Morning Father or if you prefer being called in this (other) way, Janus, Thou with whom men start business and works, do open my poem".</ref> G. Dumézil believes this custom is at the origin of the learned interpretations of Janus as a solar deity.<ref>G. Dumézil, ''La religion romaine archaïque'' (Paris, 1974), part II chapt. 3.</ref>
=== Space ===
Janus was also involved in spatial transitions, presiding over home doors, city gates and boundaries. Numerous toponyms of places located at the boundary between the territory of two communities, especially Etrurians and Latins or Umbrians, are named after the god.<ref>[[Giano dell'Umbria]], [[Torgiano]] near Perugia, [[Iano]] near Volterra.</ref> The most notable instance is the [[Ianiculum]] which marked the access to [[Etruria]] from Rome.<ref>Paulus ex Festus s.v. P. L.</ref> Since borders often coincided with rivers and the border of Rome (and other Italics) with Etruria was the [[Tiber]], it has been argued that its crossing had a religious connotation; it would have involved a set of rigorous apotropaic practices and a devotional attitude. Janus would have originally regulated particularly the crossing of this sacred river through the [[pons sublicius]].<ref>L. Adams Holland above.</ref>
The name of the Iāniculum is not derived by that of the god, but from the abstract noun ''iānus, -us''.<ref>P. Grimal above p. 40-43.</ref><ref>Paulus s. v. above : "Ianiculum dictum, quod per eum Romanus populus primitus transierit in agrum Etruscum". "It is named Janiculum because originally the Romans passed on to the Etruscan territory (ager) through it".</ref> Adams Holland opines it would have been originally the name of a small bridge connecting the [[Tiber Island]] (on which she supposes the first shrine of Janus stood) with the right bank of the river.<ref>L. Adams Holland above p. 231-3.</ref>
However Janus was the protector of doors, gates and roadways in general, as is shown by his two symbols, the key and the staff.<ref>Macrobius ''Saturnalia'' I 9 7: "But among us the name of Janus shows that he was the patron of all doorways, which is similar to Θυραίω. Indeed he is represented also with a key and a stick, as if he were the protector of all doorways and the ruler of all roadways"; Ovid ''Fasti'' I 254-5.</ref> The key too was a sign that the traveller had come to a harbour or ford in peace to exchange his goods.<ref>J. Gagé, "Sur les origines du culte de Janus", ''Revue de l'histoire des religions'' 195/1 (1979), p. 8.</ref>
The rite of the bride's oiling the posts of the door of her new home with wolf fat at her arrival, though not mentioning Janus explicitly, is a rite of passage related to the ''ianua''.
=== Rites of the Salii ===
The rites of the Salii marked the springtime beginning of the war season in March and its closing in October. The structure of the [[Patrician (ancient Rome)|patrician]] [[Sodales|sodalitas]], made up by the two groups of the Salii Palatini, who were consecrated to Mars and whose institution was traditionally ascribed to Numa (with headquarter on the Palatine), and the Salii Collini or Agonales, consecrated to Quirinus and whose foundation was ascribed to Tullus Hostilius, (with headquarter on the Quirinal) reflects in its division the dialectic symbolic role they played in the rites of the opening and closing of the military season.<ref>The two groups were of twelve people each. They stood under the patronage of the gods of the archaic triad: cf. Servius ''Aen.'' VIII 663 "… the Salii who are under the tutelage of Jupiter, Mars and Quirinus".</ref> So does the legend of their foundation itself: the peace-loving king Numa instituted the Salii of [[Mars Gradivus]], foreseeing the future wars of the Romans<ref>Livy I 20, 4.</ref> while the warmonger king Tullus, in a battle during a longstanding war with the Sabines, swore to found a second group of Salii should he obtain victory.<ref>Dionysius Halicarnasseus III 32, 4.</ref>
The paradox of the pacifist king serving Mars and passage to war and of the warmonger king serving Quirinus to achieve peace under the expected conditions highlights the dialectic nature of the cooperation between the two gods, inherent to their own function.<ref>Tullus's vow included beside the institution of the Salii also that of the [[Saturnalia]] (perhaps along with the [[Consualia]]) and of the [[Opalia]] after the storing of the harvest: all festivals related to peace, fertility and plenty.</ref> Because of the working of the talismans of the sovereign god they guaranteed alternatively force and victory, fecundity and plenty. It is noteworthy that the two groups of Salii did not split their competences so that one group only opened the way to war and the other to peace: they worked together both at the opening and the conclusion of the military season, marking the passage of power from one god to the other. Thus the Salii enacted the dialectic nature present in the warring and peaceful aspect of the Roman people, particularly the ''iuvenes''.<ref>A passage of Statius ''Silvae'' V 2, 128, to be found in a poem in honour of his friend Crispinus, a Salius Collinus, suggests clearly the difference between the functions of the arms of Quirinus and those of Mars (and Minerva): "Mars and the virgin Actea shew the points ... the arms of Quirinus ... shields born from the clouds and arms untouched by slaughter": the arms of Quirinus were peaceful.</ref>
This dialectic was reflected materially by the location of the temple of Mars outside the [[pomerium]] and of the temple of Quirinus inside it.<ref>Servius ''Aen.'' I 292 "Thence in the City there two temples of his, of Quirinus within the Urbs, as if protector but peaceful, another on the ''Via Appia'' outside the ''Urbs'' near the gate, as if warrior, or ''gradivus'' ": the gate is the ''Porta Capena''; VI 860: "Quirinus is the Mars that presides over peace and is worshipped inside the city: in fact the Mars of war has his temple outside it". Regardless of the actual date of their foundation their location is archaic: for Quirinus cf. Paulus p. 303 L and for Mars Festus p. 204 L.</ref> The annual dialectic rhythm of the rites of the Salii of March and October was also further reflected within the rites of each month and spatially by their repeated crossing of the pomerial line. The rites of March started on the first with the ceremony of the ''ancilia movere'', developed through the month on the 14th with [[Equirria]] in the [[Campus Martius]] (and the [[Mamuralia|rite of Mamurius Veturius]] marking the expulsion of the old year), the 17th with the [[Agonium Martiale]], the 19th with the [[Quinquatrus]] in the [[Comitium]] (which correspond symmetrically with the [[Armilustrium]] of 19 October), on the 23rd with the [[Tubilustrium]] and they terminated at the end of the month with the rite of the ''ancilia condere''. Only after this month-long set of rites was accomplished was it [[Glossary of ancient Roman religion#fas|fas]] to undertake military campaigns.<ref>Suetonius ''Othon'' VIII 5: "He started the expedition before it was ritually correct, without any care for religious praescriptions, but with ''ancilia''  ''moved'' and not yet ''stored'' "; Ovid ''Fasti'' III 395f.: "The arms move the fight: the fight is alien to the grooms, when they have been stored the omen shall be more propitious".</ref>
While Janus sometimes is named ''belliger''<ref>[[Lucan]] ''Pharsalia'' I 61–62: "Pax missa per orbem/ ferrea belligeri compescat limina Iani". Statius ''Silvae'' II 3,12: "belligerum Iani nemus".</ref> and sometimes ''pacificus''<ref>Martial VIII 66, 11–12.</ref> in accord with his general function of beginner, he is mentioned as ''Janus Quirinus'' in relation to the closing of the rites of March at the end of the month together with [[Pax (mythology)|Pax]], [[Salus]] and [[Concordia (mythology)|Concordia]]:<ref>Ovid ''Fasti'' III 879–882: "... Janus is to be worshipped together with mild Concord and Safety of the Roman people and the altar of Peace".</ref> This feature is a reflection of the aspect of Janus Quirinus which stresses the ''quirinal'' function of bringing peace back and the hope of soldiers for a victorious return.<ref>Servius ''Aen.'' I 291: "It is a better reason that those who go to war desire the come back."</ref><ref>The ancients give an armed and even military definition of Quirinus: Macrobius I 9 16; Ovid II 475-8; Plutarch ''Romulus '' 29, 1; ''Quaestiones Romanae'' 27; Paulus 43, 1 L. But while his armed character of is not in contradiction with the nature of Quirinus as well as of the gods of the third function, a definitely and exclusively martial character is unacceptable and looks to be a later development, due to the assimilation of Romulus with Quirinus. The legend of Romulus' later life had strong military connotations, which changed the original character of Quirinus. According to Dumezil the interpretation Quirnus-Romulus came about via a different route, i. e. the [[divine twins]] myth, of which [[Romulus and Remus]] are an instance. Their myth is representative and belongs to the category of the gods of the third function, as e.g. the [[Dioskuri]], the [[Ashvins]]. Whatever the original nature of the Sabine Quirinus, in Rome this god did not originally have a military function.</ref>
As the rites of the Salii mimic the passage from peace to war and back to peace by moving between the two poles of Mars and Quirinus in the monthly cycle of March, so they do in the ceremonies of October, the ''Equus October'' ("[[October Horse]]") taking place on the Campus Martius<ref>Festus p. 190 L.</ref> the ''Armilustrium'', purification of the arms, on the [[Aventine Hill|Aventine]],<ref>Varro ''Lingua Latina'' VI 22; V 153; Plutarch ''Quaestiones Romanae'' 23.</ref> and the [[Tubilustrium]] on the 23rd. Other correspondences may be found in the dates of the founding of the temples of Mars on 1 June and of that of Quirinus on 29 June, in the pre-Julian calendar the last day of the month, implying that the opening of the month belonged to Mars and the closing to Quirinus.
The reciprocity of the two gods' situations is subsumed under the role of opener and closer played by Janus as Ovid states: "''Why are you hidden in peace, and open when the arms have been moved?''"<ref>''Fasti'' I 277.</ref> Another analogous correspondence may be found in the festival of the [[Quirinalia]] of February, last month of the ancient calendar of Numa.<ref>C. Koch above; R. Schilling above p. 124 n. 2.</ref> The rite of the opening and closure of the Janus Quirinus would thus reflect the idea of the reintegration of the ''miles'' into civil society, i.e. the community of the ''quirites'', by playing a lustral role similar to the ''Tigillum Sororium'' and the ''{{lang|la|porta triumphalis}}'' located at the south of the Campus Martius. In Augustan ideology this symbolic meaning was strongly emphasised.<ref>Thus Ovid may conclude his passage devoted to Janus with the words "Janus, do make peace and those who administer it (Augustus and Germanicus) eternal." in ''Fasti'' I 287. Horace too mentions that Augustus closed the ''Ianum Quirini'' in ''Carmina'' IV 15, 9 and calls "Janus ... protector of the peace" in ''Epistulae'' II 1, 255.</ref>
=== Tigillum Sororium ===
{{Main|Tigillum Sororium}}
This rite was supposed to commemorate the expiation of the murder of his own sister by Marcus Horatius.<ref>Livy I 26. Dionysius of Halicarnassus III 22.</ref> The young hero with his head veiled had to pass under a beam spanning an alley. The rite was repeated every year on 1 October.<ref>CIL I 2nd p. 214: "Fasti Aru. ad Kal. Oct. : Tigillo Soror(io) ad compitum Acili"</ref> The ''tigillum'' consisted of a beam on two posts.<ref>Festus s. v. Sororium tigillum p. 380 L.: "Horatius duo tigilla tertio superiecto ... subit".</ref> It was kept in good condition at public expenses to the time of Livy. Behind the ''tigillum'', on opposite sides of the alley, stood the two altars of Janus Curiatius and Juno Sororia. Its location was on the vicus leading to the [[Carinae]], perhaps at the point of the crossing of the [[pomerium]].<ref>Livy I 26, 6 and 11 repeats twice the formula ''{{lang|la|vel intra pomerium vel extra pomerium}}''.</ref> The rite and myth have been interpreted by Dumezil as a purification and desacralization of the soldiers from the religious pollution contracted in war, and a freeing of the warrior from ''furor'', wrath, as dangerous in the city as it is necessary on campaign.<ref>G. Dumezil, ''Myths romains I. Les Horaces et les Curiaces'' (Paris, 1942), p. 112.</ref>
The rite took place on the kalends of October, the month marking the end of the yearly military activity in ancient Rome. Scholars have offered different interpretations of the meaning of Janus Curiatius and Juno Sororia. The association of the two gods with this rite is not immediately clear. It is however apparent that they exchanged their epithets, as Curiatius is connected to (Juno) Curitis and Sororia to (Janus) Geminus.<ref>M. Renard "Aspects anciens de Janus et de Junon" above p. 9 and ff. citing E. L. Shields, ''Juno'' (Northampton, Mass., 1926), p. 53.</ref> Renard thinks that while Janus is the god of motion and transitions he is not concerned directly with purification, while the arch is more associated with Juno. This fact would be testified by the epithet Sororium, shared by the ''tigillum'' and the goddess. Juno Curitis is also the protectress of the ''iuvenes'', the young soldiers.<ref>Martianus Capella ''De Nuptiis'' II 149.</ref> Paul the Deacon states that the ''sororium tigillum'' was a ''sacer'' (sacred) place in honour of Juno.<ref>Paulus s.v. Sororium tigillum p. 399 L.</ref> Another element linking Juno with Janus is her identification with Carna, suggested by the festival of this deity on the kalends (day of Juno) of June, the month of Juno.
Carna was a nymph of the sacred ''lucus'' of Helernus, made goddess of hinges by Janus with the name of [[Cardea]], and had the power of protecting and purifying thresholds and the doorposts.<ref>A. Grenier, ''Les religions étrusque et romaine'' (Paris, 1948), pp. 115 and 131</ref><ref>R. Pettazzoni, "Carna", ''Studi Etruschi'' 14 (1940), p. 163ff.</ref><ref>Ovid ''Fasti'' VI 155</ref> This would be a further element in explaining the role of Juno in the ''Tigillum''. It was also customary for new brides to oil the posts of the door of their new homes with wolf fat. In the myth of Janus and Carna (see section below) Carna had the habit when pursued by a young man of asking him out of shyness for a hidden recess and thereupon fleeing: but two headed Janus saw her hiding in a crag under some rocks. Thence the analogy with the rite of the Tigillum Sororium would be apparent: both in the myth and in the rite Janus, the god of motion, goes through a low passage to attain Carna as Horatius passes under the ''tigillum'' to obtain his purification and the restitution to the condition of citizen eligible for civil activities, including family life. The purification is then the prerequisite for fertility. The custom of attaining lustration and fertility by passing under a gap in rocks, a hole in the soil or a hollow in a tree is widespread.<ref>Roscher, ''Lexicon'', s.v. Ianus col. 21–22.</ref>
The veiled head of Horatius could also be explained as an apotropaic device if one considers the ''{{lang|la|tigillum}}'' the ''{{lang|la|iugum}}'' of Juno, the feminine principle of fecundity. Renard concludes that the rite is under the tutelage of both Janus and Juno, being a rite of transition under the patronage of Janus and of desacralisation and fertility under that of Juno: through it the ''{{lang|la|iuvenes}}'' coming back from campaign were restituted to their fertile condition of husbands and peasants. Janus is often associated with fecundity in myths, representing the masculine principle of motion, while Juno represents the complementary feminine principle of fertility: the action of the first would allow the manifestation of the other.<ref>Cf. Augustin ''De Civitate Dei'' VII 2 and 3.</ref>
== Myths ==
In discussing myths about Janus, one should be careful in distinguishing those which are ancient and originally Latin and those others which were later attributed to him by Greek mythographers.<ref>R. Schilling above p. 97.</ref> In the ''Fasti'' Ovid relates only the myths that associate Janus with [[Saturn (mythology)|Saturn]], whom he welcomed as a guest and with whom he eventually shared his kingdom in reward for teaching the art of agriculture, and to the nymph Crane, Grane, or Carna, whom Janus raped and made the goddess of hinges as [[Cardea]],<ref name="Ovid Fasti VI 101-130">Ovid ''Fasti'' VI 101–130.</ref> while in the ''Metamorphoses'' he records his fathering with [[Venilia]] the nymph [[Canens (mythology)|Canens]], loved by [[Picus]], first legendary king of the [[Aborigines (mythology)|Aborigines]].<ref>Ovid XIV 333 ff.</ref>
The myth of Crane has been studied by M. Renard<ref>M. Renard "Aspect anciens de Janus et de Junon" above pp. 13–14.</ref> and G. Dumezil.<ref>G. Dumézil ''Fêtes romaines d'été et d'automn. Suivi par dix questions romaines'' "Question X. Theologica minora" Paris 1975 p. 223ff.</ref> The first scholar sees in it a sort of parallel with the theology underlying the rite of the Tigillum Sororium. Crane is a nymph of the sacred wood of [[Helernus]], located at the issue of the Tiber, whose festival of 1 February corresponded with that of Juno Sospita:<ref>Ovid ''Fasti'' II 67–68.</ref> Crane might be seen as a minor ''imago'' of the goddess. Her habit of deceiving her male pursuers by hiding in crags in the soil reveals her association not only with vegetation but also with rocks, caverns, and underpassages.<ref>In Greece Crane, Cranea is an epithet of Athens, meaning the rocky city; the Cranai are nymphs of rocks, or Naiads of springs. L. Rocci ''Dizionario Greco -Italiano'' Roma 1972 s. v.</ref> Her nature looks to be also associated with vegetation and nurture: G. Dumezil has proved that Helernus was a god of vegetation, vegetative lushness and orchards, particularly associated with vetch. As Ovid writes in his ''Fasti'',<ref name="Ovid Fasti VI 101-130"/> 1 June was the festival day of Carna, besides being the calendary festival of the month of Juno and the festival of Juno Moneta. Ovid seems to purposefully conflate and identify Carna with Cardea in the aetiologic myth related above. Consequently, the association of both Janus and the god Helernus with Carna-Crane is highlighted in this myth: it was customary on that day to eat ivetch (mashed beans) and lard, which were supposed to strengthen the body. Cardea had also magic powers for protecting doorways (by touching thresholds and posts with wet hawthorn twigs) and newborn children by the aggression of the [[striges]] (in the myth the young Proca).<ref>Ovid ''Fasti'' VI 131–183.</ref> M. Renard sees the association of Janus with Crane as reminiscent of widespread rites of [[lustration]] and fertility performed through ritual walking under low crags or holes in the soil or natural hollows in trees, which in turn are reflected in the lustrative rite of the Tigillum Sororium.
Macrobius<ref>''Saturnalia'' I 7, 19ff.</ref> relates that Janus was supposed to have shared a kingdom with [[Camese]] in [[Latium]], in a place then named Camesene. He states that [[Hyginus]] recorded the tale on the authority of a Protarchus of [[Tralles]]. In Macrobius Camese is a male: after Camese's death Janus reigned alone. However Greek authors make of Camese Janus's sister and spouse: [[Atheneus]]<ref>Atheneus ''Deipnosophistes'' XV 46=692.</ref> citing a certain Drakon of [[Corcyra]] writes that Janus fathered with his sister Camese a son named Aithex and a daughter named Olistene.<ref>Wellman in R.E. Pauly-Wissowa V column 1663 no. 16 writes Drakon might have lived at the time of Augustus, R. Schilling thinks he lived only after Pliny the Elder. Cf. Plutarch ''Quaestiones Romanae'' 22 on Camise.</ref> Servius Danielis<ref>''Aen''. VIII 330.</ref> states [[Tiber]] (i.e., [[Tiberinus (god)|Tiberinus]]) was their son.
[[Arnobius]] writes that [[Fontus]] was the son of Janus and [[Juturna]].<ref>''Adversus Nationes'' III 29.</ref> The name itself proves that this is a secondary form of Fons modelled on Janus,<ref>Walde-Hoffmann LEW s. v. Fons.</ref> denouncing the late character of this myth: it was probably conceived because of the proximity of the festivals of Juturna (11 January) and the Agonium of Janus (9 January) as well as for the presence of an altar of Fons near the Janiculum<ref>G. Wissowa ''Religion und Kultus der Römer'' Munich 1912 p. 221. Cf. Cicero ''De Legibus'' II 56.</ref> and the closeness of the notions of spring and of beginning.
Plutarch<ref>''Quaestiones Romanae'' 22.</ref> writes that according to some Janus was a Greek from [[Perrhebia]].<ref>Comparing this tradition with [[Strabon]]'s passage in ''Geographia'' X 2, 12 (who cites [[Odyssea]] X 190–192) on the Ionians, French scholar J. Gagé has seen a Hyperborean origin of Janus, derived from the Protohellenes of Thessaly and the Pelasgians. Cf. J. Gagé, "Sur les origines du culte de Janus", ''Revue de l' histoire des religions'' 195/1 (1979), pp. 31–32.</ref>
After [[Romulus]] and his men [[The Rape of the Sabine Women|kidnapped the Sabine women]], and Rome was attacked by the Sabines under king [[Titus Tatius|Tatius]], Janus caused a volcanic hot spring to erupt, resulting in the would-be attackers being buried alive in the deathly hot, brutal water and ash mixture of the rushing hot volcanic springs that killed, burned, or disfigured many of Tatius's men. This spring is called Lautolae by Varro.<ref>Varro ''Lingua Latina'' V 156; Paulus ex Festus p. 105, 11 L.</ref> Later on, however, the Sabines and Romans agreed on creating a new community together. In honor of this, the doors of a walled roofless structure called 'The Janus' (not a temple) were kept open during war after a symbolic contingent of soldiers had marched through it. The doors were closed in ceremony when peace was concluded.<ref>Macrobius ''Saturnalia'' I 9, 17–18; Ovid ''Metamorphoses'' XIV 781–799; ''Fasti'' I 259–276; Servius ''Ad Aen.'' I 291; VIII 361; Mythographus Vaticanus III 4, 9.</ref>

In accord with his fundamental character of being the Beginner, Janus was considered by Romans the first king of Latium, sometimes along with Camese.<ref>Macrobius ''Saturnalia'' I 7, 20.</ref> He would have received hospitably the god [[Saturn (mythology)|Saturn]], who, expelled from Heaven by Jupiter, arrived on a ship to the Janiculum. Janus would have also effected the miracle of turning the waters of the spring at the foot of the [[Viminal]] from cold to scorching hot to fend off the assault of the Sabines of king [[Titus Tatius]], come to avenge the kidnapping of their daughters by the Romans.<ref>Ovid ''Fasti'' I 265–276: ''Metamorphoses'' XIV 775–800.</ref>
His temple named Janus Geminus had to stand open in times of war. It was said to have been built by king [[Numa Pompilius]], who kept it always shut during his reign as there were no wars. After him it was closed very few times, one after the end of the first Punic War, three times under [[Augustus]] and once by [[Nero]]. It is recorded that emperor [[Gordianus III]] opened the Janus Geminus.<ref>Julius Capitolinus ''Gordianus'' XXVI 3.</ref>
It is a noteworthy curiosity that the opening of the Janus was perhaps the last act connected to the ancient religion in Rome: [[Procopius]] writes<ref>Procopius ''De Bello Gothico'' I 25.</ref> that in 536, during the [[Gothic War (535–554)|Gothic War]], while general [[Belisarius]] was under siege in Rome, at night somebody opened the Janus Geminus stealthily, which had stayed closed since the 390 edict of [[Theodosius I]] that banned the ancient cults. Janus was faithful to his liminal role also in the marking of this last act.<ref>R. Schilling above p. 89.</ref>
===Distant origin hypothesis===
The uniqueness of Janus in Latium has suggested to L. Adams Holland and J. Gagé the hypothesis of a cult brought from far away by sailors and strictly linked to the amphibious life of the primitive communities living on the banks of the Tiber. In the myth of Janus, the ship of Saturn, as well as the myth of [[Carmenta]] and [[Evander of Pallene|Evander]] are reminiscent of an ancient pre-Roman sailing life. The elements that seem to connect Janus to sailing are presented in two articles by J. Gagé summarised here below.<ref>J. Gagé, "Sur les origines du culte de Janus", ''Revue de l'histoire des religions'' 195/1 and 2, pp. 3–33 and 129–151. [https://www.persee.fr/doc/rhr_0035-1423_1979_num_195_1_6814]</ref>
====1. The boat of Janus and the beliefs of the primitive sailing techniques====
;(a) The proximity of Janus and Portunus and the functions of the ''flamen Portunalis'': The temple of Janus was dedicated by [[Gaius Duilius]] on 17 August, day of the [[Portunalia]]. The key was the symbol of both gods and was also meant to signify that the boarding boat was a peaceful merchant boat.
:The ''flamen Portunalis'' oiled the arms of [[Quirinus]] with an ointment kept in a peculiar container named ''persillum'', term perhaps derived from Etruscan ''persie''.<ref>E. Peruzzi, "Un etruschismo del latino religioso", ''Rivista di Filologia Italiana e Classica'' (1976), pp. 144–148.</ref> A similar object seems to be represented in a fresco picture of the Calendar of Ostia on which young boys prepare to apply a resin contained in a basin to a boat on a cart, i.e. yet to be launched.
;(b) The ''Tigillum Sororium'': The ''Tigillum Sororium'' would be related to a gentilician cult of wood of the [[Horatii]], as surmised by the episodes of the ''pons sublicius'' defended by [[Horatius Cocles]], and of the posts of the main entrance of the temple of Jupiter Capitolinus on which [[Marcus Horatius Pulvillus]] lay his hand during the dedication rite. Gagé thinks the magic power of the ''Tigillum Sororium'' should be ascribed to the lively and burgeoning nature of wood.
====2. Religious quality of trees====
Trees as the wild olive, and the Greek or Italic lotus (''[[Celtis australis]]''), have analogous religious qualities to those of corniolum and wild fig for sailing communities: its wood does not rot in sea water, thence it was used in shipbuilding and in the making of rolls for hauling of ships overland.
====3. The depiction of Janus and Boreas as bifrons====
The depiction of both Janus and [[Boreas (god)|Boreas]] as bifrons, and seasonal elements.
;(a) The calendar of Numa and the role of Janus: Contradictions of the ancient Roman calendar on the beginning of the new year: originally March was the first month and February the last one. January, the month of Janus, became the first after several changes in the calendar. The liminal character of Janus is still present in the association to the [[Saturnalia]] of December, reflecting the strict relationship between the two gods Janus and Saturn and the rather blurred distinction of their stories and symbols.
:The initial role of Janus in the political-religious operations of January: the ''nuncupatio votorum'' spanning the year, the imperial symbol of the boat in the opening rite of the sailing season, the ''vota felicia'': Janus and his myths allow for an ancient interpretation of the ''vota felicia'', different from the Isiadic one.
;(b) The idea of the Seasons in the ancient traditions of the [[Ionian Islands]]: The crossing of the [[Hyperborean]] myths. [[Cephalonia]] as a place at the cross of famous winds. Application of the theory of winds for the navigation in the Ionian Sea. The type ''Boreas Bifrons'' as probable model of the Roman Janus.
:This observation was made first by the ''Roscher Lexicon'': "Ianus is he too, doubtlessly, a god of wind"<ref>repeated in the ''RE Pauly-Wissowa'' s.v. Boreas by Rapp, P.</ref> Grimal has taken up this interpretation connecting it to a vase with red figures representing [[Boreas (god)|Boreas]] pursuing the nymph [[Oreithyia]]: Boreas is depicted as a two headed winged demon, the two faces with beards, one black and the other fair, perhaps symbolising the double movement of the winds Boreas and Antiboreas. This proves that the Greeks of the 5th century BC knew the image of Janus. Gagé feels compelled to mention here another parallel with Janus to be found in the figure of [[Argus Panoptes|Argos]] with one hundred eyes and in his association with his murderer [[Hermes]].
;(c) Solar, solsticial and cosmological elements: While there is no direct proof of an original solar meaning of Janus, this being the issue of learned speculations of the Roman erudits initiated into the mysteries and of emperors as [[Domitian]], the derivation from a Syrian cosmogonic deity proposed by P. Grimal looks more acceptable. Gagé though sees an ancient, preclassical Greek mythic substratum to which belong [[Deucalion]] and [[Pyrrha]], and the [[Hyperborean]] origins of the Delphic cult of [[Apollo]], as well as the [[Argonauts]].<ref>M. Delcourt ''Pyrrhus et Pyrrha'' Liège 1965; G. Colli ''La sapienza greca'' I. Milano 1977 p. 27; 45–47; 431–434.</ref> The beliefs in the magic power of trees is reflected in the use of the olive wood, as for the rolls of the ship Argos: the myth of the Argonauts has links with [[Corcyra]], remembered by [[Lucius Ampelius]].<ref>''Liber memorialis'' VIII.</ref>
====4. The sites of the cults of Janus at Rome====
The sites of the cults of Janus at Rome and his associations in ancient Latium.
;(a) ''Argiletum'': Varro gives either the myth of the killing of Argos as an etymology of the word Argi-letum (death of Argos), which looks to be purely fantastic, or that of place located upon a soil of clay, ''argilla'' in Latin. The place so named stood at the foot of the [[Viminal]], the hill of the reeds. It could also be referred to the white willow tree, used to make objects of trelliswork.
;(b) The [[Janiculum]]: The [[Janiculum]] may have been inhabited by people who were not Latin but had close alliances with Rome.<ref>L. Adams Holland above p. 224ff.: conquests of Ancus Marcius; J. Gagé ''La chute des Tarquins et les debuts de la Republique romaine'' Paris 1976 p. 197 ff.</ref> The right bank of the Tiber would constitute a typical, convenient, commodious landing place for boats and the cult of Janus would have been double insofar as amphibious.
;(c) Janus in Latium: Janus's cultic alliances and relations in Latium show a pre-Latin character. Janus has no association in cult (calendar or prayer ''formulae'') with any other entity. Even though he bears the epithet of ''Pater'' he is not head of a divine family; however some testimonies lend him a companion, sometimes female, and a son and / or a daughter. They belong to the family of the nymphs or genies of springs. Janus intervenes in the miracle of the hot spring during the battle between Romulus and Tatius: [[Juturna]] and the nymphs of the springs are clearly related to Janus as well as [[Venus (mythology)|Venus]], that in Ovid's ''Metamorphoses'' cooperates in the miracle and may have been confused with [[Venilia]], or perhaps the two might have been originally one.
:Janus has a direct link only to Venilia, with whom he fathered [[Canens (mythology)|Canens]].<ref>Ovid ''Metamorphoses'' XIV 334.</ref> The magic role of the wild olive tree (''oleaster'') is prominent in the description of the duel between [[Aeneas]] and [[Turnus]]<ref>Vergil ''Aeneis'' XII 766 ff.</ref> reflecting its religious significance and powers: it was sacred to sailors, also those who had shipwrecked as a protecting guide to the shore. It was probably venerated by a Prelatin culture in association with [[Faunus]].
:In the story of [[Venulus]] coming back from [[Apulia]] too one may see the religious connotation of the wild olive: the king discovers one into which a local shepherd had been turned for failing to respect the nymphs he had come across in a nearby cavern, apparently Venilia, who was the deity associated with the magic virtues of such tree.
:Gagé finds it remarkable that the characters related to Janus are in the ''Aeneis'' on the side of the [[Rutuli]]. In the poem Janus would be represented by [[Tiberinus (god)|Tiberinus]]. Olistene, the daughter of Janus with Camese, may reflect in her name that of the olive or ''oleaster'', or of Oreithyia.<ref>G. Radke ''Die Götter Altitaliens'' Münster 1965 s.v. Olistene, or Olistine: the name might also be related to adjective ''olitana'' meaning ''vetusta'' extremely old: cf. ''Corpus Glossariorum Latinorum'' IV 264.</ref> Camese may be reflected in [[Carmenta]]: Evander's mother is from [[Arcadia (ancient region)|Arcadia]], comes to Latium as an exile migrant and has her two festivals in January: Camese's name at any rate does not look Latin.
====5. Sociological remarks====
;(a) The vagueness of Janus's association with the cults of primitive Latium: The vagueness of Janus's association with the cults of primitive Latium and his indifference towards the social composition of the Roman State suggest that he was a god of an earlier amphibious merchant society in which the role of the guardian god was indispensable.
;(b) Janus bifrons and the [[Penates]]: Even though the cult of Janus cannot be confused with that of the Penates, related with Dardanian migrants from Troy, the binary nature of the Penates and of Janus postulates a correspondent ethnic or social organisation. Here the model is thought to be provided by the cult of the ''Magni Dei'' or [[Cabeiri]] preserved at [[Samothrace]] and worshipped particularly among sailing merchants.
:The aetiological myth is noteworthy too: at the beginning one finds [[Dardanus (son of Zeus)|Dardanos]] and his brother [[Iasion|Iasios]]<ref>Dionysius of Halicarnassus I 61: Iasos would have unduely aspired to the union with Demeter; Diodorus Siculus V 49: Iasion is on the contrary asked for the union by Demeter and from it Plutos is born.</ref> appearing as auxiliary figures in a [[Phrygia]]n cult to a [[Cybele|Great Mother]].
:In Italy there is a trace of a conflict between worshippers of the Argive [[Hera]] ([[Diomedes]] and the Diomedians of the south) and of the Penates. The cult of Janus looks to be related to social groups remained at the fringe of the Phrygian ones. They might or might not have been related to the cult of the [[Dioscuri]].<ref>Objections by D. Briquel in ''MEFRA'' '''88''' 1976 p. 44 against St. Weinstock in ''Journal of Roman Studies'' 1960 p. 112 ff.</ref>
== Relationship with other gods ==
=== Janus and Juno ===
The relationship between Janus and Juno is defined by the closeness of the notions of beginning and transition and the functions of conception and delivery. The reader is referred to the above sections ''Cult epithets'' and ''Tigillum Sororium'' of this article and the corresponding section of article [[Juno (mythology)|Juno]].
=== Janus and Quirinus ===
[[Quirinus]] is a god that incarnates the ''quirites'', i.e. the Romans in their civil capacity of producers and fathers. He is surnamed ''Mars tranquillus'' (peaceful Mars), ''Mars qui praeest paci'' (Mars who presides on peace). His function of ''custos'' guardian is highlighted by the location of his temple inside the [[pomerium]] but not far from the gate of Porta Collina or Quirinalis, near the shrines of [[Sancus]] and [[Salus]].
As a protector of peace he is nevertheless armed, in the same way as the ''quirites'' are, as they are potentially ''milites'' soldiers: his statue represents him is holding a spear. For this reason Janus, god of gates, is concerned with his function of protector of the civil community. For the same reason the flamen Portunalis oiled the arms of Quirinus, implying that they were to be kept in good order and ready even though they were not to be used immediately.<ref>G. Dumézil above p. 236-238.</ref>
Dumézil and Schilling remark that as a god of the [[third function]] Quirinus is peaceful and represents the ideal of the ''pax romana'' i. e. a peace resting on victory.<ref>On the arms of the gods of the third function cf. G. Dumézil, "Remarques sur les armes des dieux de troisième fonction chez divers peuples indo-européens", ''Studi e Materiali di Storia delle Religioni'' 28 (1957), pp. 1–10.</ref>
=== Janus and Portunus ===
[[Portunes|Portunus]] may be defined as a sort of duplication inside the scope of the powers and attributes of Janus.<ref>G. Wissowa ''Religion und Kultus der Römer'' (Munich, 1912), 2nd p. 112.</ref> His original definition shows he was the god of gates and doors and of harbours. In fact it is debated whether his original function was only that of god of gates and the function of god of harbours was a later addition: Paul the Deacon writes:
: "... he is depicted holding a key in his hand and was thought to be the god of gates".
Varro would have stated that he was the god of harbours and patron of gates.<ref>''[[Scholia]] Veronensia ad Aeneidem'' V 241.</ref> His festival day named [[Portunalia]] fell on 17 August, and he was venerated on that day in a temple ''ad pontem Aemilium'' and ''ad pontem Sublicium'' that had been dedicated on that date.<ref>G. Wissowa above.</ref>
Portunus, unlike Janus, had his own [[flamen]], named ''Portunalis''. It is noteworthy that the temple of Janus in the [[Forum Holitorium]] had been consecrated on the day of the Portunalia, and that the flamen Portunalis was in charge of oiling the arms of the statue of [[Quirinus]].<ref>Festus s. v. persillum p. 238 L. The ''persillum'' was a ''rediculum'', small container in which the ointment was kept.</ref><ref>R. Schilling above p. 99 and n. 4, p. 120; G. Dumézil above part I chapt. 5 It. tr. p.237-238.</ref>
=== Janus and Vesta ===
The relationship between Janus and [[Vesta (mythology)|Vesta]] touches on the question of the nature and function of the gods of beginning and ending in [[Proto-Indo-European religion|Indo-European religion]].<ref>G. Dumézil, "De Janus à Vesta" in ''Tarpeia'' (Paris, 1946), pp. 33–113; "Vesta extrema" ''Questiunculae Indo-Italicae.12'', ''Revue d'études latins'' 39 (1961), pp. 250–257.</ref> While Janus has the first place, Vesta has the last, both in theology and in ritual (''Ianus primus, Vesta extrema'').
The last place implies a direct connexion with the situation of the worshipper, in space and in time. Vesta is thence the goddess of the hearth of homes as well as of the city. Her inextinguishable fire is a means for men (as individuals and as a community) to keep in touch with the realm of gods. Thus there is a reciprocal link between the god of beginnings and unending motion, who bestows life to the beings of this world (Cerus Manus) as well as presiding over its end, and the goddess of the hearth of man, which symbolises through fire the presence of life. Vesta is a virgin goddess, but at the same time she is called a 'mother' of Rome: She is thought to be indispensable to the existence and survival of the community.<ref>A. Brelich, ''Vesta'' (Zurich, 1949), "Janus und Vesta" p. 28ff.</ref>
== Janus in Etruria ==
It has long been believed that Janus was present among the theonyms on the outer rim of the [[Piacenza Liver]] in case 3, under the name of Aaron. This fact created a problem as the god of beginnings looked to be located in a situation other than the initial, i.e. the first case. After the new readings proposed by A. Maggiani, in case 3 one should read TINS: the difficulty has thus dissolved.<ref>A. Maggiani "Placentia" apud M. Cristofani "Rivista di di epigrafia etrusca", ''Studi Etruschi'' 49 (1981), pp. 235–283, numero 37, pp. 263–267 and "Qualche osservazione sul fegato di Piacenza", ''Studi Etruschi'' 50 (1982) (issued 1984), pp. 53–88.</ref> Aaron has thence been eliminated from Franciscan theology as this was his only attestation.<ref>C. O. Thulin, ''Die Götter des Martianus Capella und der Bronzeleber von Piacenza'' (Giessen, 1906), pp. 22–24.</ref> Maggiani<ref>Above p. 263-4.</ref> remarks that this earlier identification was in contradiction with the testimony ascribed to Varro by Johannes Lydus that Janus was named ''caelum'' among the Etruscans.<ref>Lydus ''De Mensibus'' IV 2 : cf. also Varro ''Antiquitates Rerum Divinarum'' 16 fr. 230 Cardauns = apud Augustine ''De Civitate Dei'' VII 28.</ref>
On the other hand, as expected Janus is present in region I of Martianus Capella's division of Heaven and in region XVI, the last one, are to be found the ''{{lang|la|Ianitores terrestres}}'' (along with Nocturnus), perhaps to be identified in [[Limentinus|Forculus, Limentinus and Cardea]],<ref>S. Weinstock, "Martianus Capella", ''Journal of Roman Studies'', p. 106 n. 25 on the grounds of Varro apud Augustine above VII 2 and Johannes Scotus Eriugena ''Annotationes in Marcianum'', edited by C. E. Lutz (Cambridge, Mass., 1939; reprint New York, 1970), p. 29, 8.</ref> deities strictly related to Janus as his auxiliaries (or perhaps even no more than concrete subdivisions of his functions) as the meaning of their names implies: Forculus is the god of the ''forca'', a ''iugum'', low passage, Limentinus the guardian of the ''limes'', boundary, Cardea the goddess of hinges, here of the gates separating Earth and Heaven.<ref>Tertullian ''Idolatria'' XV 5; ''De Corona Militis'' XIII 9.</ref>
The problem posed by the qualifying adjective ''terrestres'' earthly, can be addressed in two different ways.
One hypothesis is that Martianus's depiction implies a descent from Heaven onto Earth.<ref>S. Weinstock "Martianus Capella" in ''Journal of Roman Studies'' p. 104 and 106 .</ref> However Martianus's depiction does not look to be confined to a division Heaven-Earth as it includes the Underworld and other obscure regions or remote recesses of Heaven. Thence one may argue that the articulation Ianus-Ianitores could be interpreted as connected to the idea of the Gates of Heaven (the ''Synplegades'') which open on the Heaven on one side and on Earth or the Underworld on the other.<ref>S. Weinstock above p. 106 n. 25; E. L. Highbarger, ''The Gates of Dream: An archaeological examination of Vergil, Aeneid VI 893–899'' (Baltimore, 1940); [[A. K. Coomaraswamy]], ''The Door in the Sky'' (Princeton, 1997); M. Eliade ''Shamanism: Archaic Techniques of Ecstasis'' (Princeton, 2004); G. Capdeville, "Les dieux de Martianus Capella", ''Revue de l'histoire des religions'' 213/3 (1996), pp. 293–4.</ref>
From other archaeological documents though it has become clear that the Etruscans had another god who was double-faced like Janus: Culśanś, of which there is a bronze statuette from [[Cortona]] (now at Cortona Museum). While Janus is a bearded adult, Culśans is an unbearded youth, making his identification with [[Hermes]] look possible.<ref>A. Pfiffig ''Religio Etrusca'' Graz 1975 p. 330-1.</ref> However, his name is also connected with the Etruscan word for doors and gates.<ref>E. Simon, "Gods in harmony", in ''Etruscan Religion'', edited by N. Thomas De Grummond (Univ. of Texas Press, 2006) p. 58. Cf. also goddess Culśu, the gatekeeper of the Underworld, holding a torch and a key, on the sarchophagus of Hasti Afunei from [[Chiusi]].</ref>
According to Capdeville, Culśans may also be found on the outer rim of the Piacenza Liver, on case 14, in the compound form ''CULALP'', i.e., "of Culśanś and of [[Alpanu|Alpan(u)]]" on the authority of Pfiffig, but perhaps here it indicates instead the female goddess Culśu, the guardian of the door of the Underworld.<ref>A. Pfiffig above pp. 330–331 on Culśu and p. 280 on Alpanu. In Capdeville's citation it looks the author is unaware of existence of two different gods named Culśanś and Culśu respectively.</ref> Although the location is not strictly identical, there is some approximation in his situations on the Liver and in Martianus' system.
A. Audin connects the figure of Janus to Culśanś and Turms (Etruscan rendering of Hermes, the Greek god mediator between the different worlds, brought by the Etruscan from the Aegean Sea), considering these last two Etruscan deities as the same.<ref>A. Audin above p. 96.</ref> This interpretation would then identify Janus with Greek god [[Hermes]]. Etruscan medals from [[Volterra]] too show the double-headed god and the Janus Quadrifrons from Falerii may have an Etruscan origin.<ref>L. Schmitz in W. Smith above p. 551.</ref>
== Association with non-Roman gods ==
[[File:Autun Janus Temple.jpg|thumb|right|The traditional ascription of the "Temple of Janus" at [[Autun]], Burgundy, is disputed.]]
Roman and Greek authors maintained Janus was an exclusively Roman god.<ref>Ovid ''Fasti''I 90; Dionysius Halicarnasseus.</ref> This claim is excessive according to R. Schilling,<ref>R. Schilling above p. 115.</ref> at least as far as iconography is concerned. A god with two faces appears repeatedly in Sumerian and Babylonian art.<ref>A. Ungnad "Der babylonische Janus" in ''Archiv für Orientforschung'' '''5''' 1929 p. 185.</ref>
[[File:Ea (Babilonian) - EnKi (Sumerian).jpg|thumb|left|A [[cylinder seal]] depicting the gods [[Ishtar]], [[Shamash]], [[Enki]], and [[Isimud]], who is shown with two faces (circa 2300 BC)]]
The ancient [[Sumer]]ian deity [[Isimud]] was commonly portrayed with two faces facing in opposite directions. Sumerian depictions of Isimud are often very similar to the typical portrayals of Janus in ancient [[Roman art]].<ref>{{cite book|author=Ariel Golan|date=2003|title=Prehistoric Religion: Mythology, Symbolism|url=https://books.google.com/books?id=vfgoAAAAYAAJ|page=333|publisher=A. Golan |isbn=9789659055500}}</ref> Unlike Janus, however, Isimud is not a god of doorways. Instead, he is the messenger of [[Enki]], the ancient Sumerian god of water and civilization.<ref>{{cite book|author=Rafique Ali Jairazbhoy|date=1965|title=Oriental influences in Western art|publisher=Asia Pub. House|url=https://archive.org/details/orientalinfluenc0000jair|url-access=registration|page=[https://archive.org/details/orientalinfluenc0000jair/page/227 227]}}</ref> Reproductions of the image of Isimud, whose Babylonian name was Usimu, on cylinders in Sumero-Accadic art can to be found in H. Frankfort's work ''Cylinder seals'' (London 1939) especially in plates at p.&nbsp;106, 123, 132, 133, 137, 165, 245, 247, 254. On plate XXI, c, Usimu is seen while introducing worshippers to a seated god.
Janus-like heads of gods related to [[Hermes]] have been found in Greece, perhaps suggesting a compound god.<ref>J. Marcadé, "Hermès double", ''Bulletin de Correspondence Hellénique'' 76 (1952), pp. 596–624.</ref>
[[William Betham]] argued that the cult arrived from the Middle East and that Janus corresponds to the ''Baal-ianus'' or Belinus of the Chaldeans, sharing a common origin with the [[Oannes (mythology)|Oannes]] of [[Berossus|Berosus]].<ref name="royal">Royal Numismatic Society, ''Proceedings of the Numismatic Society'', James Fraser, 1837</ref>
P. Grimal considers Janus a conflation of a Roman god of doorways and an ancient Syro-Hittite uranic cosmogonic god.<ref>P. Grimal above pp. 15–121.</ref>
The Roman statue of the Janus of the Argiletum, traditionally ascribed to Numa, was possibly very ancient, perhaps a sort of [[xoanon]], like the Greek ones of the 8th century BC.<ref>P. J. Riis, ''An introduction to Etruscan art'' (Copenhagen, 1953), p. 121.</ref>
In [[Hinduism]], the image of double- or four-faced gods is quite common, as it is a symbolic depiction of the divine power of seeing through space and time. The supreme god [[Brahma]] is represented with four faces. Another instance of a four-faced god is the Slavic god [[Svetovid]].
Other analogous or comparable deities of the ''prima'' in [[Proto-Indo-European religion|Indo-European religions]] have been analysed by G. Dumézil.<ref>G. Dumezil, "Remarques comparatives sur le dieu scandinave Heimdallr", ''Études Celtiques'' (1959), pp. 263–283; "De Janus à Vesta" in ''Tarpeia'' (Paris, 1947), pp. 31–113 esp. pp. 86–88.</ref> They include the Indian goddess [[Aditi]] who is called ''two-faced'' as she is the one who starts and concludes ceremonies,<ref>Śatapatha Brāhmaṇa ([[Shatapathabrahmana]]) III 2, 4, 16 ''ubhayaḥtaśīrṣṇi'' and Eggeling's note.</ref> and Scandinavian god [[Heimdallr]]. The theological features of Heimdallr look similar to Janus's: both in space and time he stands at the limits. His abode is at the limits of Earth, at the extremity of Heaven; he is the protector of the gods; his birth is at the beginning of time; he is the forefather of mankind, the generator of classes and the founder of the social order. Nonetheless he is inferior to the sovereign god [[Oðinn]]: the ''Minor Völuspá'' defines his relationship to Oðinn almost with the same terms as those in which Varro defines that of Janus, god of the ''prima'' to Jupiter, god of the ''summa'': Heimdallr is born as the ''firstborn ''(''primigenius'', ''var einn borinn í árdaga''), Oðinn is born as the ''greatest'' (''maximus'', ''var einn borinn öllum meiri'').<ref>''Hyndluljóð'' strophe 37 and 40.</ref> Analogous Iranian ''formulae'' are to be found in an [[Avestic]] ''gāthā'' ([[Gathas]]).<ref>[[Yasna]] 45 first verses of strophes 2, 4 and 6.</ref> In other towns of ancient Latium the function of presiding over beginnings was probably performed by other deities of feminine sex, notably the ''[[Fortuna]] Primigenia'' of [[Praeneste]].

In her 1921 book ''The Witch-Cult in Western Europe'', folklorist [[Margaret Murray]] claimed that evidence found in records of the [[early modern witch trials]] showed the witches' god, usually identified in the records as [[the Devil]], was in fact often a male priest dressed in a double mask representing Janus. Murray traced the presence of a man dressed with a mask on the back of his head at some witch meetings to confessions of accused witches in the [[Pyrenees]] region, and one statement in particular that the leader of the witches appeared "''comme le dieu Janus''" ("as the god Janus"). Via the etymology given by James Frazier, Murray further connected the figure on Janus or Dianus in the witch-cult with the more well known goddess of witchcraft, [[Diana (mythology)|Diana]].<ref name=murray1921>Murray, Margaret. 1921. [https://archive.org/details/witchcultinweste00murr ''The Witch-Cult in Western Europe'']</ref> Both Murray's contemporaries and modern scholars have argued that Murray's hypothesis and the connections she drew between Janus and Diana, and linking the early modern witch trials with ancient pagan beliefs, are dubious.<ref>{{cite news |title=Margaret Murray: Who Believed Her and Why? |last=Simpson |first=Jacqueline |year=1994 |journal=Folklore |volume=105 |pages=89–96 |jstor=1260633 }}</ref>

First of all, Janus has two faces, which we interpreted as the duality of [[sadomasochism|SM]] (one's dominant and submissive sides). Second, he's the Roman god of portals, and more importantly, of beginnings and endings. To us, it represents the beginning of one's acceptance of self, the beginning of freedom from guilt, and the eventual ending of self-loathing and fear over one's SM desires. And third, Janus is the Roman god of war—the war we fight against stereotypes commonly held against us.</blockquote>In the 1987 [[Thriller (genre)|thriller]] novel ''[[The Janus Man]]'' by British novelist [[Raymond Harold Sawkins]], Janus is used as a metaphor for a Soviet agent infiltrated into British Secret Intelligence Service – "The Janus Man who faces both East and West".
