The Romans believed in a polytheistic religion, which means they worshiped multiple gods and goddesses. They sacrificed animals and built temples to honor and appease these deities. The temples served as a place for worship, offerings, and festivals. The sacrifice of animals was seen as a way to communicate with the gods and goddesses, and ask for their blessings or aid. These rituals were an important aspect of daily life for the Romans, and were seen as a way to maintain a good relationship with their gods and ensure their protection and favor.
