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 (or one of his circle) that would have been made in the fourth century BC.
The enlarged copy was made for the Baths of Caracalla in Rome (dedicated in 216 AD), where the statue was recovered in 1546,[4] and is now in the Museo Archeologico Nazionale in Naples.
The type was well known in antiquity, and among many other versions a Hellenistic or Roman bronze reduction, found at Foligno is in the Musée du Louvre.
Leaning on his gnarled club, which is draped in the skin of the Nemean lion, he holds the golden apples stolen from the Hesperides, hiding them behind his back, in his right hand.
It stood for generations in its own room at Palazzo Farnese, Rome, where the statue was surrounded by frescoed depictions of the hero's mythical feats that were created by Annibale Carracci and his studio, executed in the 1590s.
[7] Goethe, in his Italian Journey, recounts his differing impressions upon seeing the Hercules with each set of legs, however, marvelling at the clear superiority of the original ones.
Leaning on his knobby club which is draped with the pelt of the Nemean lion, he holds the apples of the Hesperides, but conceals them behind his back cradled in his right hand.
By 1562 the find was already included in the set of engravings for Speculum Romanae Magnificentiae ("Mirror of Rome's Magnificence") and connoisseurs, artists, and tourists gaped at the original, which stood in the courtyard of the Palazzo Farnese, protected under the arcade.
Later (in 1591) Goltzius recorded the less-common rear view, in a bravura engraving (illustration, right), which emphasizes the already exaggerated muscular form with swelling and tapering lines that flow over the contours.
In Scotland a copy made in lead in 1743 by John Cheere is sited incongruously in the central Highlands, overlooking the recently restored Hercules Garden in the grounds of Blair Castle.
