The fullest surviving version of how Heracles briefly took on Atlas's burden comes from the mythographer Apollodorus, writing his Bibliotheca centuries after Hesiod, and it turns the episode into a small comedy of persuasion rather than a simple feat of strength. Sent to fetch the golden apples of the Hesperides as one of his labors, Heracles is advised that only Atlas, father of the nymphs who guard the tree, can safely pick the apples himself, so Heracles offers to hold up the sky in Atlas's place while Atlas goes to fetch them, a bargain Atlas accepts readily enough, glad of even a brief respite from his endless burden. Atlas returns with the apples but, having tasted freedom, announces he will deliver them to King Eurystheus himself rather than take back the sky, leaving Heracles trapped; Heracles, thinking quickly, agrees but asks Atlas to hold the heavens just a moment longer so he can adjust a cushion on his shoulders for comfort, and the instant Atlas obliges by taking the sky back, Heracles picks up the apples and walks away, leaving the Titan exactly where he started.
The episode gives Atlas one of the only moments in surviving myth where he is an active character rather than a static, suffering image, and it casts him, briefly, as someone capable of hoping for release and clever enough to attempt securing it, only to be outmaneuvered by a hero whose own cleverness, rather than force, resolves the standoff. Later retellings vary in small details, some having Heracles use different pretexts, but the core structure, a trade proposed, freedom briefly tasted, and a trick that restores the original arrangement, remains stable across the ancient sources that preserve it.
