Gaia
Earth as a goddess, from Greek Gaia, spouse of Uranus, mother of the Titans, personification of gaia "earth," as opposed to heaven, "land," as opposed to sea, "a land, country, soil," a collateral form of ge (Dorian ga) "earth," of unknown origin, perhaps pre-Indo-European. The Roman equivalent goddess of the earth was Tellus (see tellurian), sometimes used in English poetically or rhetorically for "Earth personified" or "the Earth as a planet."
