Early Roman Religion In the early know part of history 7th Century BC Romans had formed a religion that dealt with the worship of new high gods. This was enabled by the influence of the Greek religion, which in most aspects was the same. In this style of religion there were different gods for every element that made up the world. The main god that controlled most of the power was Jupiter. His control was over the sky and the weather so he was very important to the farmers. With him was the god Mars, and at least one goddess Juno who was in charge of supervising the life of women. The most deities of the period were figures of limited functions.
