Atlas was a Titan of the second generation, son of Iapetus and Clymene, brother of Prometheus and Epimetheus. After the Titanomachy, Zeus sentenced him — for he had been a leader on the Titans' side — to bear the heavens upon his shoulders forever. He stood at the western edge of the world, where the sun set into the Ocean, and held up the firmament; his name became attached to the great mountain-range of northwestern Africa (the modern Atlas Mountains), and from there in modern times to the volume of geographical maps that bear his image on their frontispiece — a use that goes back to Mercator's collection of 1595, on whose cover Atlas was depicted holding the world.
The principal narrative-episode involving Atlas is his encounter with Heracles, who came to him in the course of one of his labors (the eleventh, the apples of the Hesperides). Heracles offered to take up the burden of the heavens for a moment if Atlas would fetch the golden apples from the garden where his daughters the Hesperides kept them. Atlas, glad of any respite, agreed, and went off to fetch the apples; when he returned with them, he proposed to leave Heracles bearing the sky permanently while he himself delivered the apples to Eurystheus. Heracles, anticipating this, asked only that Atlas resume the burden for a moment that he might adjust his cloak as a cushion; Atlas obliged, took up the heavens again — and Heracles seized the apples and departed. Atlas was thus left bearing the sky for eternity, except in the Perseus-and-Medusa episode, in which the hero used Medusa's head to turn him to stone, becoming thereby the petrified Atlas Mountain (a different version, harder to harmonize with the Heracles narrative).
