In ancient Roman religion and myth, Janus is the god of beginnings, gates, transitions, time, duality, doorways, passages, and endings.
Janus presided over the beginning and end of the 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 times of war and closed to mark the arrival of peace (which did not happen very often). As a god of transitions, he had functions about birth and journeys, exchange, traveling, trading, and shipping.
Two-faced Janus is one of the oldest divinities of the ancient Latins and Romans, venerated since the beginning of the city of Rome. Depicted with two faces, one mirroring the other, Janus is the god of beginnings, doors and passageways. The two-faced god, with his looking to the future and the past simultaneously, represented the god of gods moments of transition and the cycle of the seasons.
Janus is “deorum deus”, god of the gods and also "Ianus pater", Janus the Father. According to legend it was the god Quirino himself, or Romulus, who raised him in a temple after the victory over the Sabines.
In the Roman myth, the two-faced Janus is the ancient God and King of Latium. He is a beneficent and magnanimous god who gives to the Aboriginal people and the natives the "civilization" and founds a city on the Gianicolo. Not only that, Janus is the father of the god of the Tiber, Tiberino, which he had after his relationship with a nymph, Camese.
But the importance of Janus does not end here: it is always he to welcome Saturn into Latium because his son Jupiter had dethroned him as "father of the gods" Arrived in Latium, according to the ancients Roman legends, Saturn becomes the king of the region, with the permission of Janus; thus began the golden age of ancient Latium.
