Final answer:
Roman religion was based on the Greek pantheon and included many gods and rituals. The Capitoline Triad was central, and foreign gods and cults were often absorbed. Exclusive practices from mystery cults and early Christianity, which didn't partake in Roman state rituals like animal sacrifice, were not included.
Step-by-step explanation:
Roman culture was heavily influenced by other civilizations, especially in terms of religious practices. Roman religion adopted many gods and was focused on rituals such as prayers, vows, oaths, and sacrifice. The Roman religion was initially based on the Greek pantheon, and the Romans were known for their inclusiveness, readily absorbing foreign gods and cults into their religious system. Important gods in the traditional Roman pantheon included the Capitoline Triad of Juno, Jupiter, and Minerva. However, certain religious elements were not included in the Roman state religion, particularly the exclusive worship and practices seen in the mystery cults and early Christianity, which refused to participate in the state's practices such as animal sacrifice.
