Answer:
The religion of ancient Rome evolved over time, with two distinct phases: the Western or "Old Roman" religion, which was the original religion of Rome and its early inhabitants, and the Eastern or "Mystery" religion, which emerged in the Hellenistic period as Rome came into contact with Greek culture. The Western religion was a polytheistic system that involved the worship of a pantheon of gods and goddesses, who were believed to have power over various aspects of life. The Eastern religion, on the other hand, focused on mystery cults and the worship of individual gods and goddesses, with a greater emphasis on personal salvation and an afterlife. Both religions played an important role in shaping Roman culture and society, and their beliefs and practices were influenced by the diverse cultures and traditions of the Mediterranean world.
