Gaea (jēˈə) [key], in Greek religion and mythology, the earth, daughter of Chaos, both mother and wife of Uranus (the sky) and Pontus (the sea). Among Gaea's offspring by Uranus were the Cyclopes, the Hundred-handed Ones (the Hecatoncheires), and the Titans. To Pontus she bore five sea deities. Because Uranus had imprisoned her sons she helped bring about his overthrow by the Titans, who were led by Kronos. She was worshiped as the primal goddess, the mother and nourisher of all things. The Romans identified her with Tellus.
