Etymology

The etymologies proposed by the ancient fall into three categories: each of them bears implications about the nature of the god itself.

The first one is grounded into a detail of the definition of Chaos given by Paul the Deacon

: hiantem, hiare, be open, from which word Ianus would derive for the subtraction of the aspiration. This etymology is related to the notion of Chaos which would define the primordial nature of the god. The idea of an association of the god to the Greek concept of Chaos looks contrived, as the initial function of Janus suffices to explain his place at the origin of time.

Another etymology proposed by Nigidius Figulus

However the form Dianus postulated by Nigidius is not attested.

Theology and functions

While the fundamental nature of Janus is debated, the set of its functions may be seen as organized around a simple principle: in the view of most modern scholars that of presiding over all beginnings and transitions, whether abstract or concrete, sacred or profane. Interpretations concerning the fundamental nature of the god either limit it to this general function itself or emphasize a concrete or particular aspect of it (identifying him with light the sun, the moon, time, movement, the year, doorways, bridges etc.) or see in the god a sort of cosmological principle, i. e. interpret him as a uranic deity.

Almost all these interpretations of the Modern had already been formulated by the Ancient.

The function of god of beginnings has been clearly expressed by numerous ancient sources, among them most notably perhaps by Cicero, Ovid and Varro. As a god of motion he looks after passages, causes the startings of actions, presides on all beginnings and since movement and change are bivalent, he has a double nature, symbolised in his two headed image. He has under his tutelage the stepping in and out of the door of homes, the ianua, which took its name from him, and not viceversa. Similarly his tutelage extends to the covered passages named iani, and foremostly to the gates of the city, including the cultual gate of the[Argiletum, named Ianus Geminus or Porta Ianualis from which he protects Rome against the Sabins. He is also present at the Sororium Tigillum

The connexion of the notions of beginning (principium) and movement and transition (eundo), and thence time, has been clearly expressed by Cicero.

, the hands of his statue were postured so as to show number 355, later 365, symbolically expressing his mastership over time. He presides over the concrete and abstract beginnings of the world, such as religion and the gods themselves, he too holds the access to Heaven and other gods: this is the reason why men must invoke him first, regardless of the god they want to pray or placate. He is the initiator of the human life, of new historical ages, and economical enterprises: in myth he first minted coins and the as

Because of his initial nature he was frequently used to symbolize change and transitions such as the progression of past to future, of one condition to another, of one vision to another, the growing up of young people, and of one universe to another. He was also known as the figure representing time because he could see into the past with one face and into the future with the other. This is also one of the explanations of his image with two heads looking in opposite directions. Hence, Janus was worshipped at the beginnings of the harvest and planting times, as well as marriages, deaths and other beginnings. He was representative of the middle ground between barbarity and civilization, rural country and urban cities, and youth and adulthood. Having jurisdiction on beginnings Janus had an intrinsic association with omens and auspices.

In one of his works G.

) who show a sort of mutual solidarity: the concept of god of ending is defined in connexion to the human referential, i.e. the current situation of man in the universe, and not to endings as transitions, 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, and the goddess of ending to any of the three categories onto which the goddesses are distributed. There is though a greater degree of fuzziness concerning the function and role of female goddesses, which may have formed a preexisting structure allowing the absorption of the local Mediterrenean mother goddesses, nurturers and protectresses . 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 uranic god, but would rather be a structural feature inherent to the theology of such gods. The fall of uranic primordial gods into the condition of deus otiosus is a well known phenomenon in the history of religions. Mircea Eliade

A similar solar interpretation has been offered by A. Audin who interprets the god as the issue of a long process of development, started 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

 himself. About the exact location and aspect of the temple there has been much debate among scholars. In the course of wars, the gates of the Janus were opened, and in its interior sacrifices and vaticinia were held to forecast the outcome of military deeds. The doors were closed only during peacetime, an extremely rare event. 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; in times of war it was said to be open to allow the return of the people on duty.

Cult epithets

Carmen Saliare

The opening verses of the carmen were (as to be expected) devoted to honoring Janus and were thence named versus ianuli. Paulus-Festsus s.v. axamenta p. 3 L mentions the versus ianuli, iovii, iunonii, minervii. Only part of the versus ianuli and two of the iovii are preserved.

The manuscript has:

(paragraph 26): "cozeulodorieso. omia ũo adpatula coemisse./ ian cusianes duonus ceruses. dun; ianusue uet põmelios eum recum";

(paragraph 27): "diuum êpta cante diuum deo supplicante.""ianitos".

Many reconstructions have been proposed:
they vary widely on some points and are all tentative, however one can identify with certainty some epithets:

Cozeiuod orieso. Omnia vortitod Patulti; oenus es

iancus (or ianeus), Iane, es, duonus Cerus es, duonus Ianus.

Veniet potissimum melios eum recum.

Diuum eum patrem (or partem) cante, diuum deo supplicate.

The epithets that can be identified are: Cozeuios, i. e. Conseuius the Sower, that opens the carmen and is attested as an old form of Consivius in Tertullian

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.

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 to a remarkable extent too. Macrobius 's list and explanation are probably based directly on Cornelius Labeo

 and mentions one of his works, Fasti. In relating Ianus 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 looks probable he just received a sheer list with no interpretations appended and he interpreted it according to his own views.

Pater is perhaps the most frequent epithet of Janus, found also in the composition Ianuspater. Even though numerous gods share this cultual epithet it looks the Romans felt it was typically pertinent to Janus. When he is invoked along other gods usually only he is called pater. To Janus the title is not just a term of respect but primarily it marks his primordial role. He is the first of the gods and thence their father: the formula quasi deorum deum corresponds to diuum deus of the carmen Saliare. To the same complex can be reconducted the expression duonus Cerus in which Cerus means creator and is considered a masculine form related to Ceres.
Lydus gives Πατρίκιος (Patricius) and explains it as autóchthon: since he does not give another epithet corresponding to Pater it is legitimate to infer that Lydus understands Patricius as a synonymous of Pater. There is no evidence connecting Janus to gentilician cults or identifying him as a national god particularly venerated by the oldest patrician families.

Geminus is the first epithet in Macrobius 's list. Even though the etymology of the word is unclear, it is certainly related to his most typical character, that of having two faces or heads. The proof are the numerous equivalent expressions. The origin of this epithet might be either concrete, referring directly to the image of the god reproduced on coins and supposed to have been introduced by king Numa
Numa Pompilius
Numa Pompilius was the legendary second king of Rome, succeeding Romulus. What tales are descended to us about him come from Valerius Antias, an author from the early part of the 1st century BC known through limited mentions of later authors , Dionysius of Halicarnassus circa 60BC-...

 in the sanctuary at the lowest point of the Argiletum, or to a feature of the Ianus of the Porta Belli that had a double gate ritually opened at the beginning of wars, or abstract deriving metaphorically from the liminal, intermediary functions of the god themselves: both in time and space passages put into communication two different spheres, realms or worlds. The Janus quadrifrons or quadriformis, brought according to tradition from Falerii in 241 BC and installed by Domitian in the Forum Transitorium, 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 become a new epithet though.

Patulcius and Clusivius or Clusius too are epithets related to an inherent quality and function of doors, that of standing open or shut. Janus as the Gatekeeper has jurisdiction on every kind of doors and passage and the power of opening or closing them. Servius interprets (only Patulcius) in the same way. Lydus gives a wrog translation, "αντί του οδαιον": however this interpretation reflects one of the attributes of the god, i. e. that of being the protector of roads. Elsewhere Lydus cites the epithet θυρέος to justify the key held by Janus. The antithetic quality of the two epithts is meant to refer to the alternance of opposite conditions and is commonly found in the indigitamenta: Macrobius cites the instances of Antevorta and Postvorta in relation to Janus who are the personification of two indigitations of Carmentis.
These epithets are associated with the ritual function of Janus in the opening of the of the Porta Ianualis or Porta Belli. The rite might go back to times predating the founding of Rome. Poets tried and 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.

Quirinus is a debated epithet. According to some scholars, mostly French, it looks to be strictly related to the same ideas of the passage of the Roman people from war back to peace, i. e. 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. Other scholars, mainly German, think it is on the opposite related to the martial character of god Quirinus, interpretation which is supported by numerous ancient sources: Lydus, Cedrenus, Macrobius, Ovid, Plutarch and Paul the Daecon. Schilling and Capdeville counter that it is his function of presiding on the come back of peace that got Janus this epithet, as is confirmed by his association on March 30 to Pax
Pax (mythology)

, even though it is true that Janus as god of all beginnings presides also to that of war and is thence often called belliger bringer of war 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. C. Koch on the other hand sees the epithet Janus Quirinus as a reflection of a patronage of the god on 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.
The compound term Ianus Quirinus was particularly in vogue at the time of Augustus as its peaceful interpretation fitted particularly well the augustan ideology of the Pax Romana.

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 defeated king or chief of an enemy army, those conquered by a common soldier, be consacrated to Ianus Quirinus. R. Schilling on his part proposes to understand the reference of this rite to Ianus Quirinus in the original prophetic interpretation, which ascribes to him the last and conclusive spoils of the history of Rome.

The epithet Ποπάνων (Popanōn) is attested only by Lydus, 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 and by Paul. This cake was named ianual but the related epithet of Janus could not plausibly have been Ianualis: it has been suggested Libo which remains sheerly hypothetic. The context could allow an Etruscan etymology.

Janus owes his epithet of Iunonius to his function of patron of all kalends, which are also associated to 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".

. 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: i.e. whether Janus was a debased ancient uranic supreme god or Janus and Jupiter were coexistent and their distinction was structurally inherent to their original theology. Among Francophone scholars P. Grimal and implicitly and partially M. Renard and V. Basanoff have supported the view of a uranic supreme god against G. Dumézil and R. Schilling. Among Anglophone scholars J. G. Frazer and A.B. 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 favours delivery, women's physiological cycle and opens doors. Moreover, besides the kalends Janus and Juno are also associated in the rite of the Tigillum Sororium of October 1, in which they bear the epithets of Janus Curiatius and Juno Sororia: these epithets which show a crossing and swapping of functional qualities between the gods are the most remarkable and apparent proof of their proximity. This rite is discussed in detail in the section below.

Consivius sower, is an epithet that reflects the tutelary function of the god on 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. Augustine shows astonishment at the fact some of the dii selecti may be engaged in such tasks: "In fact Janus himself first, when pregnancy is conceived,... opens the way to the receiving of the semen" . 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 thence started his enumeration of gods from Janus, following the pattern of the Carmen Saliare. 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."

 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 looks that Consus cannot be etymologically related to adjective consivius or conseuius, found in Ops Consivia and thence the implied notion of sowing.

Κήνουλος (Coenulus) and Κιβουλλιος (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 the text of Cedrenus due to a paleographic error: only Coenulus is certainly an epithet of Janus and the adjective used to explain it, meaning to present and to treat well at dinner, reminds a ritual invocation at the beginning of meals, wishing the diners to make good flesh. This is one of the features of Janus as shown by the myth that associates him with Carna, Cardea
Cardea
Cardea or Carda was the ancient Roman goddess of the hinge , Roman doors being hung on pivot hinges.

 and other ancient authors explain Curiatius by the aetiologic legend of the Tigillum, i. e. the expiation undergone by P. Horatius victorious over the Alban Curiatii, for the murder of his own sister, by walking under the beam with his head veiled. G. Capdeville sees this epithet as related exclusively to the characters of the legend and the rite itself: he invoks the analysis by G. Dumézil as his authority. At the beginning it was probably a sacrum entrusted to the gens Horatia that allowed the desacralisation of the iuvenes at the end of the military season, later transferred to the state. Janus 's patronage in a rite of passage would be natural. The presence of Juno would be related to the date (Kalends), her protection of the iuvenes, soldiers, or the legend itself. M. Renard connects its meaning to the cu(i)ris, 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. R. Schilling opines it is related to curia
Curia

, as the Tigillum was located not far from the curiae veteres: however this interpretation, even though supported by an inscription (lictor curiatius ) is considered unacceptable by M. Renard for the different quantity of the u, brief in curiatius as well as in curis, Curitis and long in 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. However the etymology of Curiatius remains uncertain. On the role of Janus in the rite of the Tigillum Sororium see also the section below.

Rites

The rites concerning Janus were numerous. Owing to the versatile and far reaching character of the basic function of the god, marking 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 the closing of the military season, in March and October respectively. These included the rite of the arma movere on March 1 and that of the arma condere at the end of the month performed by the Salii
Salii
In ancient Roman religion, the Salii were the "leaping priests" of Mars supposed to have been introduced by King Numa Pompilius. They were twelve patrician youths, dressed as archaic warriors: an embroidered tunic, a breastplate, a short red cloak , a sword, and a spiked headdress called an apex...

, and the Tigillum Sororium on October 1.The anniversaries of the dedication of the temples of Mars on June 1 (a date that corresponded with the festival of Carna, a deity associated with Janus: see below) and of that of Quirinus on June 29 (which was the last day of the month in the prejulian calendar) had a close association with Janus Quirinus. These important rites are discussed in detail in the sections below.

Any rite or religious action whatever required the invoking of Janus in the first place, to which corresponded an invocation to Vesta

 had been consecrated (by consul Caius Duilius in 260 BC). 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.

Beginning of the year

The Winter solstice was thought to happen on December 25. January 1 was new year 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 same reason too everybody devoted a short time to his usual business exchanged dates, figs and honey as a token of well wishing and gifts of coins called strenae. Cakes made of spelt (far) and salt were offered to the god and burnt on the altar. Ovid states that in most ancient times there were no animal sacrifices and gods were propitiated with offerings of spelt and pure salt. This libum was named ianual and it was probably correspondent to the summanal offered the day before the Summer solstice to god Summanus

Beginning of the month

At the kalends of each month the 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.

Beginning of the day

Morning belonged to Janus: men started their daily activities and business. Horace calls him Matutine Pater, morning father. G. Dumézil thinks this custom is at the origin of the learned interpretations of Janus as a solar deity.

Space

Janus was also involved in the spatial aspect of transitions as that of 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. The most notable instance is the Ianiculum which marked the access to Etruria
Etruria

, 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 not every kind of transition, but particularly the crossing of this sacred river through the pons sublicius

The earliest known bridge of ancient Rome, Italy, the Pons Sublicius, spanned the Tiber River near the Forum Boarium downstream from the Tiber Island, near the foot of the Aventine Hill. According to tradition, its construction was ordered by Ancus Martius around 642 BC, but this date is...

However Janus was the protector of doors, gates and roadways in general, as is shown by his two symbols, the key and the staff. The key too was a sign that the traveller had come to a harbour or ford in peace in order to exchange his goods.

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 rittes of the Salii marked the springtime beginning of the war season in March and its closing in October. The structure itself of the patrician 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. 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. And the warmonger king Tullus, in a battle during a longstanding war with the Sabines vowed the foundation of a second group of Salii should he obtain victory. 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. Because of the working of the talismans of the sovereign god they guaranteed alternatively force and victory and 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: both at the openeing and the conclusion of the military season they worked together, 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. This dialectic was reflected materially by the location of the temple of Mars outside the pomerium

 and of the temple of Quirinus inside it. 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 fist with the ceremony of the ancilia movere, developed through the month on the 14 with Equirria

 on the 23. Other correspondences may be found in the dates of the founding of the temples of Mars on June 1 and of that of Quirinus on June 29 that in prejulian calendar was 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 situation of the two gods 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?" Another analogous correspondence may be found in the festival of the Quirinalia of February, last month of the ancient calendar of Numa. The rite of the opening and closure of the Janus Quirinus would thence reflect the idea of the reintegretation of the miles into the civil society, i.e. the community of the quirites by playing a lustral role similar to the Tigillum Sororium and the porta triumphalis located at the south of the Campus Martius. In the augustan ideology this symbolic meaning has been strongly emphasised.

Tigillum Sororium

This rite was supposed to commemorate the expiation of the murder of his own sister by Marcus Horatius. The young hero had to pass under a beam which spanned an alley with his head veiled. The rite was repeated every year on October 1. The tigillum consisted of a beam on two posts. It was kept in good condition at public expenses to the time of Livy. Behind the tigillum on the 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

. The rite and myth have been interpreted by G. Dumezil as a purification and desacralization of the soldiers from the religious pollution contracted at war, and a freeing of the warrior from the furor, wrath, dangerous within the city as necessary in campaign.

The rite takes place on the kalends of October, 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 in this rite is not immediately perspicous. It is though apparent that they exchange their epithets as Curiatius is connected to (Juno) Curitis and Sororia to (Janus) Geminus. M. Renard thinks that while Janus is the god of motion and transitions he is not concerned with purification directly: the arch too is more associated to 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. Paul the Deacon states that the sororium tigillum was a sacer (sacred) place in honour of Juno. Another element that involves Juno in association with Janus is her identification with Carna
Carna
-Places:*Cârna, a commune in Dolj County, Romania*Càrna, an island in Loch Sunart on the west coast of Scotland*Carna, County Galway, a village in Connemara in the west of Ireland...

, suggested by the festival of this deity on the kalends (day of Juno) of June, the month Juno. Carna was a nymmph 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 the thresholds and the posts of doors. 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 for a hidden recess out of her shyness and thereupon fleeing: two headed Janus though 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, passes under a low passage to attain Carna as Horatius does pass 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 gape in rocks, a hole in the soil or a hollow in a tree is widespread. The veiled head of Horatius could also be explained as an apotropaic device if one considers that the tigillum is the iugum of Juno, the feminine principle of fecundity. Renard concludes remarking 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 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 one would allow the manifestation of the other.

The myth of Crane has been studied by M. Renard and G. Dumezil. 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 February 1 corresponded with that of Juno Sospita: 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. Her nature looks to be also associated with vegetation and nurture: G. Dumezil has proved that Helernus was a god of vegetation, vegetative lushiousness and orchards, particularly associated with vetch. As Ovid writes in his Fasti, June 1 was the festival day of Carna, besides being the kalendary 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 god Helernus with Carna-Crane is highlighted in this myth: it was customary on that day eating vetch 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). M. Renard sees the association of Janus with Crane as reminiscent of widespread rites of lustration and fertility performed through the 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.

. The name itself proves that this is a secondary form of Fons modelled on Janus, denouncing the late character of this myth: it was probably conceived because of the proximity of the festivals of Juturna (January 11) and the Agonium of Janus (January 9) as well as for the presence of an altar of Fons near the Janiculum and the closeness of the notions of spring and of beginning.

Plutarch writes that according to some Janus was a Greek from Perrhebia.

, 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. 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.

Origin, legends and history

's edict banned the ancient cults. Janus was faithful to his liminal role also in the marking of this last act.

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 are remininscent of an ancient Preroman sailing life. The elements that connect Janus to sailing are summarised here below as presented in the work of Gagé.

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 C. Duilius on August 17, 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
Quirinus
In Roman mythology, Quirinus was an early god of the Roman state. In Augustan Rome, Quirinus was also an epithet of Janus, as Janus Quirinus. His name is derived from Quiris meaning "spear."-History:...

 with an ointment kept in a peculiar container named persillum, term perhaps derived from Etruscan persie. 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 standing on a cart, i.e. yet to be launched.

b) The Tigillum Sororium would be related to a cult of wood of the Horatii
Horatii
According to Livy, the Horatii were male triplets from Rome. During a war between Rome and Alba Longa during the reign of Tullus Hostilius , it was agreed that settlement of the war would depend on the outcome of a battle between the Horatii and the Curiatii...

 lay his hand during the dedication rite. Gagé thinks the magic power of the Tigillum Sororium should be due to the living and burgeoning nature of wood.

2. Falacer
Falacer
Falacer, or more fully dīvus pater falacer, was an ancient Italian god, according to Varro. Hartung is inclined to consider him an epithet of Jupiter, since falandum, according to Festus, was the Etruscan name for "heaven."...

 and flamen Falacer as related to a sacred tree useful in shipbuilding. This flamen would be related to Janus as the flamen Portunalis is because of the association of pater Falacer and shipping.

a) The name of divus pater Falacer would be that of a Sabine god similar to Quirinus, i.e. a spear god from the town of Falacrinae. The term is related to falarica, a javelin soaked in pitch, ending with a point of inflammable material. Falas in Etruscan means pole or tower. The name could be related to that of the faba graeca the Greek lotus, imported from Syria (Celtis australis
Celtis australis
Celtis australis, commonly known as the European nettle tree, Mediterranean hackberry, lote tree, or honeyberry, is a deciduous tree that can grow 20 or 25 meters in height....

). This tree would have been used among certain communities as the wild olive was to make rolls in order to haul ships upon. The name of the flamen would reflect an ancient name of this tree later corrupted into faba.

b) Religious quality of trees as the wild olive (analogous to that of corniolum and wild fig) to sailing communities: it does not rot in sea water, thence it was used in shipbuilding and the making of rolls for the hauling of ships overland.

3. Janus and the depiction of Boreas as Bifrons: climatological 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 afterwards and through several manipulations. The liminal character of Janus is though present in the association to the Saturnalia
Saturnalia

 of December, reflecting the strict relationship between the two gods and the rather blurred distinction of their stories and symbols. The initial role of Janus in the political-religious operations of January: nuncupatio votorum spanning the year, imperial symbol of the boat in the rite of opening of the sailing season of 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
Ionian Islands
The Ionian Islands are a group of islands in Greece. They are traditionally called the Heptanese, i.e...

. 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.

The observation has been made first by the Roscher Lexicon: "Ianus is he too, doubtlessly, a god of wind" and repeated in the RE Pauly-Wissowa s.v. Boreas by Rapp. P. Grimal has taken up this interpretation connecting it to a vase with red figures representing Boreas pursuing the nymph Oreithyia
Oreithyia
Orithyia ; ) was the daughter of King Erechtheus of Athens and his wife, Praxithea, in Greek mythology. Her brothers were Cecrops, Pandorus, and Metion, and her sisters were Procris, Creusa, and Chthonia....

: 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 the Greek of the V century BC did know the image of Janus. Gagé feels compelled to mention here another parallel with Janus to be found in the figure of Argos
Argos
Argos is a city and a former municipality in Argolis, Peloponnese, Greece. Since the 2011 local government reform it is part of the municipality Argos-Mykines, of which it is a municipal unit. It is 11 kilometres from Nafplion, which was its historic harbour...

, 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
Deucalion
In Greek mythology Deucalion was a son of Prometheus and Pronoia. The anger of Zeus was ignited by the hubris of the Pelasgians, and he decided to put an end to the Bronze Age. Lycaon, the king of Arcadia, had sacrificed a boy to Zeus, who was appalled by this savage offering...

. The beliefs in the magic power of trees is reflected in the use of the olive wood, as for the rolls of the ship Argo: the myth of the Argonauts has links with Corcyra, remembered by Ampelius.

4. 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 is not reliable, or the place standing upon a soil of clay, argilla. However the names in -etum are usually referred to trees. 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. The word could also be linked to the Argei
Argei
Argei may refer to:* Argei , ritual figures in ancient Roman religion, and also their shrines* Argei - olive oil manufacturer...

 the 27 or 30 dolls thrown into the Tiber in the rite of May 15. On them the more accepted opinion (at the time, 1979) is that they represented Greeks, Argei being their ancient designation by the Romans. The rite could be a substitution rite for human sacrifices or be original as such. The most supported opinion among the Ancient was that of a rite of substitution of human sacrifices to Saturn
Saturn (mythology)
In ancient Roman religion and myth, Saturn was a major god presiding over agriculture and the harvest time. His reign was depicted as a Golden Age of abundance and peace by many Roman authors. In medieval times he was known as the Roman god of agriculture, justice and strength. He held a sickle in...

 ascribed to Hercules
Hercules

. At any rate the rite must be associated to a local Preroman life linked to the Tiber, to a river religion in which the reeds harvested in the river itself or its banks had a peculiar value. Janus though is not present in this rite.

b) The Janiculum
Janiculum
The Janiculum is a hill in western Rome, Italy. Although the second-tallest hill in the contemporary city of Rome, the Janiculum does not figure among the proverbial Seven Hills of Rome, being west of the Tiber and outside the boundaries of the ancient city.-Sights:The Janiculum is one of the...

 may have been inhabited by people who were not Latin but had close alliances with Rome. The right bank of the Tiber would constitute a typical, commodious landing place for boats and the cult of Janus would have been double as far as amphibious.

c) Janus's cultic alliances and relations in Latium show a Prelatin character. Janus has no association in cult (calendar or prayer formulae) with any other entity. Even though he has the epithet of Pater he is no 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
Juturna
In the myth and religion of ancient Rome, Juturna was a goddess of fountains, wells and springs. She was a sister of Turnus and supported him against Aeneas by giving him his sword after he dropped it in battle, as well as taking him away from the battle when it seemed he would get killed...

, that in the Ovid's Metamorphoses cooperates in the miracle and that may have been confused with Venilia, or perhaps the two were originally one. Janus has a direct link only to Venilia with whom he fathered Canens

. The magic role of the wild olive tree (oleaster) is prominent in the description of the duel between Aeneas
Aeneas
Aeneas , in Greco-Roman mythology, was a Trojan hero, the son of the prince Anchises and the goddess Aphrodite. His father was the second cousin of King Priam of Troy, making Aeneas Priam's second cousin, once removed. The journey of Aeneas from Troy , which led to the founding a hamlet south of...

 too we see the religious connotation of the wild olive: the king discovers one into which a local shepherd had been had been turned for failing to respect some nymphs he had come across in a nearby cavern, apparently Venilia, as she 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

, comes to Latium as an exile migrant and has her two festivals in January: Camese's name does not look Latin.

5. Sociological remarks.

a) The vagueness of Janus's association with the cults of primitive Latium and his indifference towards social composition of the Roman State suggest the inference that he was a god of an earlier amphibious merchant society in which the role of the guardian 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
Cabeiri

c) The ianitrices in Roman law. The term is attested by Modestinus in the Digesta 38, 10, 4, 6 and glossed by Isidorus

 Origines 9, 7, 17. It denotes the spouses of the brothers of one's husband: it is attested only in the imperial period and in the juridical language. It has a symmetric correspondent in levir brother of one's husband. It is possible to suppose that the word ianitrix may at its origin have issued from the cult of Janus, which could have given special functions to women married to the two undivisible companions while later it got fixed to a special sense of relations. This topic bears on the matrimonial practices of early Roman society which show traces of a regimen different from the classic one, i. e. monogamic with exogamy.

. As a protector of peace he is nevertheless armed, in the same way as the quirites are, as they are potentially milites soldiers: his staue 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. 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.

 may be defined as a sort of duplication inside the scope of the powers and attributes of Janus. 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. His festival day named Portunalia fell on August 17, and he was venerated on that day in a temple ad pontem Aemilium and ad pontem Sublicium that had been dedicated on that date. Portunus, unlike Janus, had his own flamen

Janus and Vesta

The relationship between Janus and Vesta
Vesta (mythology)
Vesta was the virgin goddess of the hearth, home, and family in Roman religion. Vesta's presence was symbolized by the sacred fire that burned at her hearth and temples...

 touches on the question of the nature and function of the gods of beginning and ending in Indo-European religion. 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 unextinguishable fire is a means for men (as individuals and community) whereby keeping 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 considered the mother of Rome: she is thought to be indispensable to the existence and survival of the community.

Janus in Etruria

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. Ani has thence been eliminated from Etruscan theology as this was his only attestation. Maggiani 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.
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 Ianitores terrestres (along with Nocturnus), perhaps to be identified in Forculus, Limentinus

Cardea
Cardea or Carda was the ancient Roman goddess of the hinge , Roman doors being hung on pivot hinges.

, 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. 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. 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 theologem of the Gates of Heaven (the Synplegades) which open on the Heaven on one side and on Earth or the Underworld on the other.

From other archaeological documents though it has become clear that the Etruscans had another god iconographically corresponding to Janus: Culśanś, of which there is a bronze statuette from Cortona

 look possible. His name too is connected with the Etruscan word for doors and gates. According to Capdeville he may also be found on the outer rim of the Piacenza Liver on case 14 in the compound form CULALP i. e. "of Culśans and of Alpan(u)" on the authority of Pfiffig, but perhaps here it is the female goddess Culśu, the guardian of the door of the Underworld. Although the location is not strictly identical there is some approximation in his situations on the Liver and in Martianus's system. A. Audin connects the figure of Janus to Culsans 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 one. This interpretation would then identify Janus with Greek god Hermes

Association with non-Roman gods

Romans and Greek authors maintained Janus was an exclusively Roman god. This Roman pretence looks to be haphardous and excessive according to R. Schilling, at least as far as iconography is concerned. The god with two faces appeared repeatedly in Babylonian art. Reproductions of the image of such a god, named Usmu, on cylinders in Sumero-Accadic art is to be found in H. Frankfort's work Cylinder seals (London 1939) especially in plates at p. 106, 123, 132, 133, 137, 165, 245, 247, 254. On plate XXI, c, Usmu is seen while introducing worshippers to a seated god.

 who is called two faced as is the one who starts and concludes ceremonies, 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 the 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 sovereign god Oðinn: the Minor Völuspá defines his relationship to Oðinn almost with the same terms as 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).
