Rhea (; , ) is the Titaness daughter of the earth goddess Gaia and the sky god Uranus, in Greek mythology and sister and wife to Cronus. In early traditions, she is known as "the mother of gods" and therefore is strongly associated with Gaia and Cybele, who have similar functions. The classical Greeks saw her as the mother of the Olympian goddesses and gods, but not as an Olympian goddess in her own right. The Romans identified her with Magna Mater (their form of Cybele), and the Goddess Ops.
