The Farnese Hercules is an ancient statue of Hercules, probably an enlarged copy made in the early third century AD and signed by Glykon, who is otherwise unknown; he was an Athenian but he may have worked in Rome. Like many other Ancient Roman sculptures it is a copy or version of a much older Greek original that was well known, in this case a bronze by Lysippos that would have been made in the fourth century BC. This original survived for over 1500 years until it was melted down by Crusaders in 1205 during the Sack of Constantinople. The enlarged copy was made for the Baths of Caracalla in Rome, where the statue was recovered in 1546, and is now in the Museo Archeologico Nazionale in Naples. The heroically-scaled Hercules is one of the most famous sculptures of antiquity, and has fixed the image of the mythic hero in the European imagination.

Lysippos was a Greek sculptor of the 4th century BC. Together with Scopas and Praxiteles, he is considered one of the three greatest sculptors of the Classical Greek era, bringing transition into the Hellenistic period. Problems confront the study of Lysippos because of the difficulty in identifying his style in the copies which survive. Not only did he have a large workshop and many disciples in his immediate circle, but there is understood to have been a market for replicas of his work, supplied from outside his circle, both in his lifetime and later in the Hellenistic and Roman periods. The Victorious Youth or Getty bronze, which resurfaced around 1972, has been associated with him.
