    Quick Answer

    Jupiter is the supreme deity of the Roman pantheon, ruling over the sky, thunder, and law. He is the Roman counterpart of the Greek Zeus, sharing the same myths and attributes while holding a central role in Roman state religion.

    Core Myth

    Jupiter inherited the mythology of Zeus through the process of interpretatio romana — the Roman practice of identifying their gods with Greek equivalents. As the supreme Roman deity, Jupiter presided over the sky, weather, and the state. His temple on the Capitoline Hill was the most important religious site in Rome. The Romans adopted Zeus's myths wholesale — Jupiter overthrew Saturn (Kronos), wielded thunderbolts, and ruled from the heavens — while adding distinctly Roman elements such as his role as the divine guarantor of oaths, treaties, and the Roman state itself.

    Later Traditions

    Jupiter remained the chief god of the Roman state religion until the adoption of Christianity. The planet Jupiter and the word 'jovial' derive from his name.
