As the god of gates and portals, Janus holds the power to open and close the passageways between different realms and time periods. His name is derived from the Latin word "ianua," meaning door or gateway, further emphasizing his role as the guardian of thresholds.

The Mythological Origins of Janus

According to Roman mythology, Janus has no clear parentage and is considered a primordial god. Some legends suggest that he is the son of Caelus (the sky) and Terra (the earth), while others propose that he emerged from Chaos, the primordial void.

He presides over important milestones in life, such as births, marriages, and the start of new ventures.

As the god of endings, Janus is also invoked during funerals and the conclusion of significant events or time periods.

The Symbolism of Janus’ Two Faces

It was customary for the Romans to invoke Janus before entering or leaving a building, as well as before embarking on important journeys.

The Romans built shrines dedicated to Janus, known as "ianus," which served as sacred spaces for rituals and offerings. These shrines were typically situated at the entrances of cities, marking the transition between the outside world and the sacred city. The Janus shrine consisted of a small temple-like structure with doors on each end, symbolizing the god’s association with gates and portals.

Rituals and Offerings to Honor Janus

The Romans held various rituals and made offerings to honor Janus throughout the year. On the first day of each month, known as the Kalends, the Romans would offer prayers and sacrifices to Janus as a way to invoke his blessings for the month ahead. During the festival of the New Year, known as the "Agonalia," the Romans would present offerings to Janus in gratitude for the previous year and to seek his guidance for the coming year.
