Lysippos (/laɪˈsɪpɒs/; Greek: Λύσιππος) 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 of identifying his style among the copies which survive. Not only did he have a large workshop and a large number of 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.
