Jupiter (Iupiter; Jove) (Jove) Roman The supreme god of the Roman pantheon; son of Saturn and Ops; husband of Juno. Jupiter was an ancient sky god of Latium, in central Italy, before the rise of Roman power. He was master of thunder, lightning, rain, and light, and also the giver of victory and peace. Jupiter was the special protector of Rome. Eventually, he became the supreme god of the Romans. Jupiter was the principal god of the two divine trios worshiped by the Romans. The older trio, Jupiter, Mars, and Quirinus, were worshiped in the early years of Rome as a regional power. As Rome grew to a republic and a great military power in the Mediterranean, the religion changed and people worshiped Jupiter as the most powerful member of the supreme trio that included Juno and Minerva. Romans built great temples to Jupiter on the Capitoline Hill. Jupiter is also the name of the largest planet in our solar system.
