In Roman mythology, the god of gates and doors is known as Janus. He is typically depicted with two faces, symbolizing his ability to look both into the past and the future. Janus represents transitions, beginnings, and endings, holding significant importance in Roman culture, particularly at the start of the year. His domain over doorways metaphorically highlights the choices and passages in life. Festivals honoring Janus involved rituals for protection and guidance, emphasizing the belief that beginnings should be approached with respect and consideration for what has come before.
