Jupiter (Jove, Optimus Maximus)
Jupiter is the supreme god of the Roman pantheon, called dies pater, "shining father". He is a god of light and sky, and protector of the state and its laws. He is a son of Saturn and brother of Neptune and Juno (who is also his wife). The Romans worshipped him especially as Jupiter Optimus Maximus (all-good, all-powerful). This name refers not only to his rulership over the universe, but also to his function as the god of the state who distributes laws, controls the realm and makes his will known through oracles. His English name is Jove.
He had a temple on the Capitol, together with Juno and Minerva, but he was the most prominent of this Capitoline triad. His temple was not only the most important sanctuary in Rome; it was also the center of political life. Here official offerings were made, treaties were signed and wars were declared, and the triumphant generals of the Roman army came here to give their thanks.
Other titles of Jupiter include: Caelestis (heavenly), Lucetius (of the light), Totans (thunderer), Fulgurator (of the lightning). As Jupiter Victor he led the Roman army to victory. Jupiter is also the protector of the ancient league of Latin cities. His attribute is the lightning bolt and the eagle is both his symbol and his messenger.
Jupiter is completely identical with the Greek Zeus
