Rhea

Summary
Rhea is the Titaness daughter of Gaia and Uranus, sister and wife to Cronus. She is the mother of the Olympian gods and goddesses. Cronus sired six children by Rhea: Hestia, Hades, Demeter, Poseidon, Hera and Zeus, in that order. He swallowed them all as soon as they were born except Zeus, since Cronus had learned from Gaia and Uranus that he was destined to be overthrown by his own child, just as he had overthrown his own father.
