Kronos or Cronus (both: krōˈnəs) [key], in Greek religion and mythology, the youngest Titan, son of Uranus and Gaea. With the help of his mother, he led the Titans in the revolt against Uranus and ruled the world. He married his sister Rhea and fathered the great gods—Zeus, Poseidon, Demeter, Hera, Hades, and Hestia. Because he was fated to be overthrown by one of his children, he swallowed them all as infants until Rhea hid Zeus and presented Kronos with a stone wrapped in a blanket, which he ate. Later Zeus tricked him into disgorging his children. Zeus then led the Olympian gods in overthrowing Kronos in the battle called the Titanomachy, described by Hesiod. Kronos and all the defeated Titans, except Atlas, were exiled. Kronos is equated with the Roman Saturn and was probably a god of a pre-Hellenic people.
