The Cult
Ianus had no flamen of his own, yet he opened every public sacrifice: prayers and libations were offered to him first, and to Vesta last. His central shrine, the Ianus Geminus in the Forum, was a small arched structure with bronze doors that stood open in war and closed in peace; Augustus's triple closing of the gates was recorded as a turning point in Roman history. The month of January bears his name, and the kalends of January were celebrated with emmer, salt, and wine. He was also invoked at marriages, births, and departures, and his association with doorways made the ianitor and the threshold part of his cult in daily Roman life.
