Cronus
God of TimeCronus was the ruling Titan who came to power by castrating his Father Uranus. His wife was Rhea. There offspring were the first of the Olympians. To insure 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 would revolt against Cronus and the other Titans, defeat them, and banish 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, honored by the Saturnalia feast.
