Jupiter, also known as Jove, was the chief ancient Roman and Italian god. He was a sky god, similar to the Greek god Zeus. Some of his epithets include Lucetius ("Light-Bringer") and Jupiter Elicius. Throughout Italy, he was worshipped on the summits of hills, and his oldest temple was on the Capitoline Hill in Rome. Jupiter was not only a protecting deity but also embodied a distinct moral conception, especially concerning oaths, treaties, and leagues. His worship was associated with conscience and the sense of obligation. The famous temple dedicated to Jupiter, Juno, and Minerva on the Capitol was a central cult in the Roman Republic and spread throughout the empire.
