Atlas

Atlas is a member of the Titan generation, son of the Titan Iapetus and an Oceanid (named in various traditions as Asia or Clymene), and brother to Prometheus, Epimetheus and Menoetius. After the Titanomachy— the cosmic war between the Titans and the Olympian gods—Zeus punished Atlas by consigning him to stand at the ends of the earth in the extreme west and support the heavens upon his shoulders for eternity. Over time his figure is doubled with place-names and other legendary figures: his daughters include groups tied to celestial and geographic features (the Hesperides, the Hyades, the Pleiades) and the nymph Calypso; later traditions identify him with the Atlas Mountains and other eponymous kings named Atlas (including a legendary king figure in later accounts), so that the name functions both as a personal mythic actor and as an etiological name for landscape and genealogical networks.

Classical literary and visual sources portray Atlas as a gigantic figure bearing a representation of the heavens — commonly a celestial sphere — on his shoulders. Sculptural exemplars (e.g., the Farnese Atlas tradition) depict him supporting a marble celestial globe, and literary accounts stress that the burden is the sky rather than the terrestrial globe. In Ovid’s formulation of the Perseus episode, Atlas is represented in a metamorphic, etiological mode: Perseus turns him to stone and Ovid poetically describes the transformation as the formation of a mountain range — "Atlas's head the peak, his shoulders ridges and his hair woods" — so that in some narratives Atlas literally becomes the Atlas Mountains.

Atlas' defining capacity is superhuman endurance: as his eternal punishment he supports the heavens and thereby sustains cosmic order. Classical and later sources additionally ascribe to him technical and intellectual skill — particularly in astronomy, mathematics and philosophy — and credit him in antiquity with inventing the first celestial sphere and with founding or exemplifying astronomical knowledge. In narrative episodes his capacities interact with heroes: he negotiates with Heracles over the retrieval of the Hesperides' golden apples (agreeing to relinquish the sky temporarily) and is in some accounts vulnerable to Perseus' use of Medusa's head, which petrifies him in etiological variants. Modern numeric strength-attributions are later extrapolations and are not attested in the classical sources summarized here.
