What was Julius caesar's religion?

Answer 1

As much as anyone believed in the religion of the time, Julius followed the ancient religion of the Romans, that is to say, very much like the Greek religion. There was a group of gods who ruled over the daily affairs of peoples' lives.

If you would like to look up Greek mythology you will see the group of gods which were in fashion at the time, and were the religion of the State. People believed (or at least followed the motions of believing) in these gods for about 3,000 years right up to the fourth century when Christianity became the religion of the Roman state.
