The Olympians are the principal Greek deities who make their home on Mount Olympus. After Zeus and his siblings overthrew their father Cronus and the other Titans, they divided the realms of sky, sea and underworld among themselves and were joined by a second generation — children such as Athena, Apollo, Artemis, Ares and Hermes.
Though the canonical list numbers twelve, ancient sources differ on the membership: Hestia and Dionysus are sometimes swapped, and Hades is traditionally excluded because he rules the underworld rather than Olympus.
