Gaia from Ancient Greek Γαῖα "land" or "earth", was the primordial Earth-goddess in ancient Greek religion. Gaia was the great mother of all: the heavenly gods and Titans were descended from her union with Uranus (the sky), the sea-gods from her union with Pontus (the sea), the Giants from her mating with Tartarus (the hell-pit) and mortal creatures were sprung or born from her earthy flesh. The earliest reference to her is Mycenaean Greek Linear B ma-ka, "Mother Gaia."
