Atlas was a second-generation Titan, who is famous for holding up the Heavens over the Earth. Atlas was the son of Iapetus and Clymene, and the brother of Menoetius, Prometheus and Epimetheus.
During the Titanomachy, he served as the general of Cronus' armies, but unlike most other Titans, he was not thrown into Tartarus, but was ordered to hold up the Heavens over the Earth, which was usually seen as keeping the primordial gods Ouranos and Gaia from mating and producing more Titans or giants.
Atlas also plays a role in the myths of two of the greatest Greek heroes: Heracles (as a part on his twelve labors) and Perseus (who in some depictions turned to stone out of pity). According to the ancient Greek poet Hesiod, Atlas stood at the western ends of the Earth. Later, he became commonly identified with the Atlas Mountains in northwest Africa and was said to be the first King of Mauretania. Atlas was said to have been skilled in philosophy, mathematics and astronomy.
In antiquity, he was credited with inventing the first celestial sphere. In some texts, he is even credited with the invention of astronomy itself. Because Atlas had bore the spheres of the heavens, he inspired the widely used image of a man carrying a celestial sphere on his back or shoulders.
"Origin: Greece. Prometheus's brother and a strong hero. After the Titans lost the battle against Zeus and the other gods, he was punished. His sentence was to hold up the weight of heaven for all eternity. He was later turned to stone out of pity."
