Above the doors of the temple is represented the hunting of the boar from Arcadia, the deed concerning Diomedes the Thracian, and the encounter on Erytheia with Geryon; there is Atlas about to transfer his burden onto Heracles' shoulders, and Heracles cleansing the land of Elis from the dung. Above the doors of the opisthodomos he is depicted taking the girdle away from the Amazon, the deed involving the hind, the bull in Knossos, the birds of Lake Stymphalus, and also those labors concerning the Hydra and the lion in the Argive territory.
