Atlas (Ἄτλας) was the primordial Titan who held up the celestial sphere. He is also the titan of astronomy and navigation. Atlas and his brother Menoetius sided with the Titans in their war against the Olympians, the Titanomachy. When the Titans were defeated, many of them were confined to Tartarus, but Zeus condemned Atlas to stand at the western edge of Gaia and hold up Uranuson his shoulders, to prevent the two from resuming their primordial embrace. Thus, he was Atlas Telamon, “enduring Atlas,” and became a doublet of Coeus, the embodiment of the celestial axis around which the heavens revolve.
