What were three important influences on ROMAN religion? Which do you feel was the most powerful? Why?

Three important influences on Roman religion were the Etruscans, the Greeks, and the Latins. I feel that the Etruscans were the most powerful influence because they were the first to introduce the concept of gods and goddesses to the Romans, as well as the idea of a pantheon of gods. They also introduced the practice of divination and the use of augury. The Etruscans also had a strong influence on the Roman calendar and the way in which festivals were celebrated.
