Source Verification: Atlas

Every claim below is either what a named ancient source attests, in its own line or section, or a point where the sources themselves disagree.

What the Sources Attest

Why was Atlas condemned to hold up the sky?

Hesiod does not narrate the cause directly on the passage describing the punishment, but later mythographers agree it followed the Titanomachy: Atlas fought on the side of Kronos and the Titans against Zeus and the Olympians, and once the Titans lost, Zeus gave Atlas an individual sentence separate from the general imprisonment of the other Titans in Tartarus, setting him to hold the sky at the western edge of the world instead.

How did Heracles get the golden apples from Atlas?

For his eleventh labor, Heracles needed the golden apples of the Hesperides, guarded in a garden only Atlas could safely approach as their father. Heracles offered to hold up the sky himself while Atlas fetched the apples. Atlas agreed, retrieved them, then tried to leave Heracles holding the sky permanently by offering to deliver the apples himself. Heracles pretended to accept, but asked Atlas to take the sky back briefly so he could adjust padding on his shoulders - and once Atlas resumed the burden, Heracles picked up the apples and left.

Did Perseus really turn Atlas to stone?

That version comes from Ovid, writing centuries after Hesiod and Apollodorus, who has Perseus ask the giant Atlas for hospitality, get refused, and use Medusa's severed head to turn him into the Atlas Mountains of North Africa. This account sits awkwardly beside the Heracles story, since in the standard genealogy Perseus's adventures happen a generation before Heracles is even born, meaning Atlas cannot both be turned to stone by Perseus and still be holding the sky for Heracles afterward. The two stories were not written to be read together.

Who were Atlas's parents and children?

Hesiod makes Atlas a son of the Titan Iapetus and the Oceanid Clymene, and a brother of Prometheus, Epimetheus, and Menoitios. Among his children, the Pleiades - including Maia, the mother of Hermes by Zeus - and the Hesperides are the best attested, which is also why Atlas alone, of all the Titans, could safely enter the Hesperides' garden to pick their golden apples.

Where Accounts Differ

Ovid's petrification story vs. the Heracles timeline

Ovid's story of Perseus petrifying Atlas into the Atlas Mountains cannot be reconciled with Apollodorus's account of Atlas still holding the sky when Heracles arrives a generation later; the two are separate literary traditions rather than one connected timeline.
