One of the most taxing of the Twelve Labours of Hercules (see post below) was the retrieval of the Apples of the Hesperides. These three apples, held in his hand, became one of the common attributes of statues of Hercules, along with the skin of the Nemean Lion, which is often found slung over his shoulder. This is a detail of the famous Farnese Hercules in Naples.
