Both these images of Herakles come from the series of metopes on the temple of Zeus at Olympia, built c. 470-456 B.C. Notice how the sculptors have aged Herakles from his first labor against the Nemean Lion, where he appears very young and tired, to one of his last, the Apples of the Hesperides. Notice too the traces of red paint on Herakles' forehead in the first image.
