This head of Hercules is based on the famed depiction of the hero by the 4th century B.C. sculptor Lysippos. The bronze original was displayed in the Agora of Sicyon in the Peloponnese. The burly hero is shown old and exhausted after his final labor, barely able to stand and so leaning on his club, holding the apples of the Hesperides behind his back. While the bronze original does not survive, it is recognized in numerous Roman copies and adaptions, including the colossal example now in Naples, the Farnese Herakles. The attribution of the type to Lysippos is based on another colossal version, now in Palazzo Pitti, Florence, which has a Greek inscription on the rock supporting the club, reading: "Lysippos' work" (see pp. 763-793, Boardman, "Herakles," in LIMC).
