Cronus, also spelled Cronos or Kronos, was a male deity in ancient Greek religion and mythology. He was the youngest of the first generation of Titans, the divine descendants of the primordial Gaia (Mother Earth) and Uranus (Father Sky). Cronus overthrew his father and ruled during the mythological Golden Age, until he was overthrown by his own son Zeus and imprisoned in Tartarus. Cronus was the god of time, in particular, time when viewed as a destructive, all-devouring force. He was also associated with agriculture, and in Attica, his festival, the Kronia, celebrated the harvest and resembled the Saturnalia. Cronus was married to his sister Rhea, and they had five children: Hestia, Demeter, Hera, Hades, and Poseidon. However, he swallowed each of his children as they were born, in fear of a prophecy that he would be overthrown by his own child. Rhea managed to save the youngest, Zeus, by hiding him away on the island of Crete and fed Cronus a stone wrapped in swaddling clothes. Zeus grew up, forced Cronus to disgorge his swallowed offspring, and led the Olympians in a ten-year war against the Titans, driving them in defeat into the pit of Tartarus.
