Zeus was the youngest son of the Titans Cronus and Rhea and the brother of the deities Poseidon, Hades, Hestia, Demeter, and Hera. According to one of the ancient myths of the birth of Zeus, Cronus, fearing that he might be dethroned by one of his children, swallowed them as they were born. Upon the birth of Zeus, Rhea wrapped a stone in swaddling clothes for Cronus to swallow and concealed the infant god in Crete (Kríti), where he was fed on the milk of the goat Amalthaea and reared by nymphs. When Zeus grew to maturity, he forced Cronus to disgorge the other children, who were eager to take vengeance on their father. In the war that followed, the Titans fought on the side of Cronus, but Zeus and the other gods were successful, and the Titans were consigned to the abyss of Tartarus. Zeus henceforth ruled over the sky, and his brothers Poseidon and Hades were given power over the sea and the underworld, respectively.
