In ancient Roman religion and myth, Janus (Latin: Ianus, pronounced [ˈjaː.nus]) is the god of beginnings and transitions, and thereby of gates, doors, doorways, passages and endings. He is usually depicted as having two faces, since he looks to the future and to the past. The Romans named the month of January (Ianuarius) in his honor.
Janus presided over the beginning and ending of conflict, and hence war and peace. The doors of his temple were open in time of war, and closed to mark the peace. As a god of transitions, he had functions pertaining to birth and to journeys and exchange, and in his association with Portunus, a similar harbor and gateway god, he was concerned with travelling, trading and shipping.
Janus had no flamen or specialized priest (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, and was ritually invoked at the beginning of each one, regardless of the main deity honored on any particular occasion.
The ancient Greeks had no equivalent to Janus, whom the Romans claimed as distinctively their own. Modern scholars, however, have identified analogous figures in the pantheons of the Near East. His name in Greek is ‘Ιανός (Ianós).
Attributes:
Associated with doorways and gates, Janus is the god of beginnings. Since he looks both ways, the term Janus-faced is used to describe someone who is duplicitous. He was also considered the guardian of peace, a time at which when the door to his shrine was closed.
Honors:
The most famous temple to Janus in Rome, on the Argiletum, is called theIanus Geminus ‘Twin Janus’. When its doors were open, neighboring cities knew that Rome was at war. When the doors were closed, Rome was at peace. In his account of his accomplishments, Augustus says the gateway doors were closed only twice before him, by Numa (235 B.C.) and Manlius (30 B.C.). Augustus closed them 3 times, in 29 after Actium, in 25, and a debated third time.
There were other temples for Janus, one on his hill, the Janiculum, and another built, in 260 at the Forum Holitorium, by C. Duilius for a Punic War naval victory.
God of change and time:
Janus frequently symbolized change and transitions such as the progress of future to past, 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. 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
Takeaway: The roman god janus has two faces, symbolising the past and the future, war and peace, beginnings and endings – the start and the ending, basically complimentary elements representing a transition of time. It is interesting to see the connection between his two faces, with transition. In the context of masks, one face has to be the dominant one in order for it to work. I’ve never thought of having two faces not layered, not covering the other but placed from one end of the spectrum to another. Whatever in between symbolising change/transition/movement.
