Cronus

a son of Uranus and Ge, and the youngest among the Titans. He was married to Rhea, by whom he became the father of Hestia, Demeter, Hera, Hades, Poseidon, and Zeus. Cheiron is also called a son of Cronus. (Hesiod. Theog. 137, 452, Apollod. i. 1. §3)

At the instigation of his mother, Cronus unmanned his father for having thrown the Cyclopes, who were likewise his children by Ge, into Tartarus. Out of the blood thus shed sprang up the Erinnyes.

When the Cyclopes were delivered from Tartarus, the government of the world was taken from Uranus and given to Cronus, who in his turn lost it through Zeus, as was predicted to him by Ge and Uranus.

The Romans identified their Saturnus with the Cronus of the Greeks.
