The Myth of Janus

Janus was primarily a Roman deity — the two-faced god of beginnings, transitions, doorways, and endings — but the Greeks knew a parallel figure.‍​‌​‍​‍​‍​‍​‌​‌​‍​‍​‌​‌​‌​‍​‍​‌​‌​‌​‌​‍​‍​‌​‌​‌​‍​‍​‍​‍​‌​‌​‌​‌ His two faces looked simultaneously to past and future, and he presided over every threshold and passage. January bears his name. His temple in Rome was closed only in times of peace — a rarity. Some Greek traditions linked him to the Titan Kronos, who fled to Italy after Zeus overths threw him. Others connected him to the founding myths that tied Troy to Rome through Aeneas. While Athena and Apollo governed wisdom and foresight among the Greeks, Janus represented a distinctly Italian concept: the sacred nature of doorways, beginnings, and the passage between states of being.
