the garden of the Hesperides. Heracles first caught the Old Man of the Sea, the shapeshifting sea god, to learn where the Garden of the Hesperides was located. In some variations, Heracles, either at the start or at the end of this task, meets Antaeus, who was invincible as long as he touched his mother, Gaia, the Earth. Heracles killed Antaeus by holding him aloft and crushing him in a bear hug. Herodotus claims that Heracles stopped in Egypt, where King Busiris decided to make him the yearly sacrifice, but Heracles burst out of his chains. Heracles finally made his way to the garden of the Hesperides, where he encountered Atlas holding up the heavens on his shoulders. Heracles persuaded Atlas to get the three golden Apples for him by offering to hold up the heavens in his place for a little while. Atlas could get the apples because, in this version, he was the father or otherwise related to the Hesperides. When Atlas returned, he decided that he did not want to take the heavens back, and instead offered to deliver the apples himself, but Heracles tricked him by agreeing to remain in place of Atlas on the condition that Atlas relieve him temporarily while Heracles adjusted his cloak. Atlas agreed, but Heracles reneged and walked away with the apples. According to an alternative version, Heracles slew Ladon, the dragon who guarded the apples, instead. Eurystheus was furious that Heracles had accomplished something that Eurystheus thought could not possibly be done. Twelfth: Cerberus The twelfth and final labour was the capture of Cerberus, the multi-headed dog that was the guardian of the gates of the Underworld. To prepare for his descent into the Underworld, Heracles went to Eleusis (or Athens) to be initiated in the Eleusinian Mysteries. He entered the Underworld, and Hermes and Athena were his guides. While in the Underworld, Heracles met Theseus and Pirithous. The two companions had been imprisoned by Hades for attempting to kidnap Persephone. One tradition tells of snakes coiling around their legs, then turning into stone. Another that Hades feigned hospitality and prepared a feast inviting them to sit; they unknowingly sat in chairs of forgetfulness and were permanently ensnared. When Heracles had pulled Theseus first from his chair, some of his thigh stuck to it (this explains the supposedly lean thighs of Athenians), but the Earth shook at the attempt to
