>>16611959Rome's official state religion was paganism, a syncretic paganism of their territory. They had gods from all over the place with shrines on Capitoline Hill and in the Forum, they're all still there. The modern Pope sits in a Roman Pagan building on a Roman Pagan throne.
Paganism survived as Catholicism, heck before they revised the calendar of saints and the breviary they had St Saturn and St Jupiter and St Mithras, etc.
