Gaea the Mother of Everything Beautiful in the world. Born spontaneously – either out of Nothingness or out of Chaos – Gaea brought forth Uranus, with whom she subsequently mated to give birth to the Titans, themselves parents of most of the Olympians.
Gaea rebelled against the reigns of all three rulers of the universe (Uranus, Kronos, Zeus), but, ultimately, she had to accept her grandson Zeus as the supreme king of all gods and men.
Gaea (the Earth), “the ever-sure foundation of all the deathless ones who hold the peaks of snowy Olympus,” was the first deity to be born after Chaos, the gaping emptiness, came into being.
She was followed by Tartarus (the Underworld) and Eros (Love). Some believe that these three were, in fact, all children of the dark primeval void, but, most probably, they belonged to the same – the very first – generation of gods.
