In Greek mythology, chief of the gods (Roman Jupiter). He was the son of Kronos, whom he overthrew; his brothers included Hades and Poseidon, his sisters Demeter and Hera. As the supreme god he dispensed good and evil and was the father and ruler of all humankind. His emblems are the thunderbolt and aegis (shield), representing the thunder cloud. He ate his pregnant first wife Metis (goddess of wisdom), fearing their child (Athena) would be greater than himself. His second wife was Hera, but he also fathered children by other women and goddesses. The offspring, either gods and goddesses or godlike humans, included Apollo, Artemis, Castor and Polydeuces/Pollux, Dionysus, Hebe, Heracles, Hermes, Minos, Perseus, and Persephone.
