The most likely identity of this athlete is the discus thrower that Pliny tell us was by Naukydes, a sculptor from Argos who mostly portrayed victorious athletes in bronze. Unlike the famous all-action discus thrower by Myron, here the athlete is preparing for his throw. The feminine-looking head joins poorly and therefore probably does not belong with the body
