Pausanias Description of Greece 6.3.11

[11] After Hysmon comes the statue of a boy wrestler from Heraea in Arcadia , Nicostratus the son of Xenocleides. Pantias was the artist, and if you count the teachers you will find five between him and Aristocles of Sicyon .
  Dicon, the son of Callibrotus, won five footraces at Pytho , three at the Isthmian games, four at Nemea , one at Olympia in the race for boys besides two in the men's race. Statues of him have been set up at Olympia equal in number to the races he won. When he was a boy he was proclaimed a native of Caulonia , as in fact he was. But afterwards he was bribed to proclaim himself a Syracusan.
