Cronus was the Titan father of the six original Olympians.
Cronus was the youngest of the twelve Titans, the children of Gaia and Uranus. After overthrowing Uranus, he became the ruling god of the cosmos and took his sister Rhea as his wife. Their children were Hestia, Demeter, Hera, Hades, Poseidon, and Zeus—the six deities traditionally identified as the original Olympian siblings.
A prophecy warned Cronus that one of his own children would depose him. To prevent that fate, he swallowed each child as soon as Rhea gave birth. Rhea saved Zeus by hiding him in Crete and presenting Cronus with a stone disguised as an infant. Once grown, Zeus made Cronus release the swallowed gods, who became his allies in the Titanomachy.
Cronus is commonly confused with the primordial deity Chronos, whose name is associated with time in later traditions. The Titans Oceanus, Iapetus, and Hyperion were Cronus’s siblings, not the father of the six Olympians. Cronus’s Roman counterpart was Saturn.
