Gaia

Gaia or Gaea, known as Earth or Mother Earth (the Greek common noun for "land" is ge or ga). She was an early earth goddess and it is written that Gaia was born from Chaos, the great void of emptiness within the universe, and with her came Eros. She gave birth to Pontus (the Sea) and Uranus (the Sky). This was achieved parthenogenetically (without male intervention). Other versions say that Gaia had as siblings Tartarus (the lowest part of the earth, below Hades itself) and Eros, and without a mate, gave birth to Uranus (Sky), Ourea (Mountains) and Pontus (Sea). http://www.pantheon.org/articles/g/gaia.html (external link)
