Cronus was the ruling Titan who came to power by castrating his father Uranus. His wife was Rhea, while their offspring were the first of the Olympians. To ensure his safety, Cronus ate each of the children as they were born. This worked until Rhea, unhappy at the loss of her children, tricked Cronus into swallowing a rock, instead of Zeus. When he grew up, Zeus revolted against Cronus and the other Titans, defeating them, and banishing them to Tartarus in the underworld.
Cronus managed to escape to Italy, where he ruled as Saturn. The period of his rule was said to be a golden age on earth, honoured by the Saturnalia feast. A festival was also held in Athens, honouring Cronus; it was called Kronia and it took place on the twelfth day of the month Hekatombaion.
Cronus is also called Saturn, Kronos, Cronos.
