Atlas was a leader of the Titans in their war against Zeus and after their defeat he was condemned to carry the heavens upon his shoulders. Atlas was also the god who instructed mankind in the art of astronomy, a tool which was used by sailors in navigation and farmers in measuring the seasons.

Heracles encountered the Titan during his quest for the Golden Apples of the Hesperides. He agreed to take the heavens upon his shoulders while Atlas fetched the apples. The hero also slew the Hesperian Dragon and built two great pillars at the ends of the earth, perhaps to relieve the Titan of his labour.

In a late myth, Atlas was transformed into the stony Atlas mountains by Perseus using the Gorgon‘s head.
