Passage 6.3.5
Ἵππον δὲ Ἠλεῖον πυγμῇ παῖδας κρατήσαντα ἐποίησε Δαμόκριτος Σικυώνιος, ὃς ἐς πέμπτον διδάσκαλον ἀνῄει τὸν Ἀττικὸν Κριτίαν· Πτόλιχος μὲν γὰρ ἔμαθεν ὁ Κορκυραῖος παρʼ αὐτῷ Κριτίᾳ, Πτολίχου δὲ ἦν μαθητὴς Ἀμφίων, Πίσων δὲ ἀνὴρ ἐκ Καλαυρείας ἐδιδάχθη παρʼ Ἀμφίονι, ὁ δὲ παρὰ τῷ Πίσωνι Δαμόκριτος.
Damokritos of Sicyon made the statue of Hippos of Elis, who had won the boys' boxing match. Damokritos' teaching lineage went back, through five masters, to the Attic sculptor Kritias. For Ptolichus of Corcyra learned directly under Kritias himself; Amphion was a pupil of Ptolichus; from Amphion was taught Pison, a man from Calaureia; and Damokritos was instructed by this Pison.
