Greek & Roman perspectives
Janus
No equivalent; Greek writers on Rome noted him as distinctively and uniquely Roman.
No direct Greek equivalent
Held supreme archaic status: invoked first in every prayer and offering, before even Jupiter, because every transaction needs an opening. The doors of his Forum shrine stood open in war and shut in peace - closed only a handful of times in all Roman history (under Numa, after the First Punic War, and under Augustus). Festival the Agonalia, 9 January.
05 · Extensive analysis
A closer reading
Janus is the most distinctively Roman of all the gods, with no Greek model. He is the god of the threshold in every sense: the physical doorway and city gate, the first month, the first moment of any action, and the passage between war and peace. His two faces let him look backward and forward at once. Because every beginning fell under his power he was named first in prayers, ahead of Jupiter, and the opening or closing of his shrine's double doors was one of the great public signals of the condition of the Roman state.
