Gaia (mythology)

In Greek mythology, Gaia, (GAY-ə or GAH-yə; from Ancient Greek Γαῖα, a poetical form of Γῆ Gē, Ge, "land" or "earth";) also spelled Gaea, was the personification of the Earth and one of the Greek primordial deities. Gaia was the great mother of all: the primal Greek Mother Goddess; creator and giver of birth to the Earth and all the Universe; the heavenly gods, the Titans, and the Giants were born to her. The gods reigning over their classical pantheon were born from her union with Uranus (the sky), while the sea-gods were born from her union with Pontus (the sea). Her equivalent in the Roman pantheon was Terra.

Etymology

The Greek word γαῖα (transliterated as gaia) is a collateral form of γῆ (gē, Doric γᾶ ga and probably δᾶ da) meaning Earth, a word of uncertain origin.R. S. P. Beekes has suggested a Pre-Greek origin. It, however, could be related to the Avestan word gaiia 'life;' cf. Av. gaēθā '(material) world, totality of creatures' and gaēθiia 'belonging to/residing in the worldly/material sphere, material'; and probably even Av, gairi 'mountain'.
