Passage 6.4.5
ὁ δὲ παῖς ὁ ἀναδούμενος ταινίᾳ τὴν κεφαλὴν ἐπεισήχθω μοι καὶ οὗτος ἐς τὸν λόγον Φειδίου τε ἕνεκα καὶ τῆς ἐς τὰ ἀγάλματα τοῦ Φειδίου σοφίας, ἐπεὶ ἄλλως γε οὐκ ἴσμεν ὅτου τὴν εἰκόνα ὁ Φειδίας ἐποίησε. Σάτυρος δὲ Ἠλεῖος Λυσιάνακτος πατρός, γένους δὲ τοῦ Ἰαμιδῶν, ἐν Νεμέᾳ πεντάκις ἐνίκησε πυκτεύων καὶ Πυθοῖ τε δὶς καὶ δὶς ἐν Ὀλυμπίᾳ· τέχνη δὲ Ἀθηναίου Σιλανίωνος ὁ ἀνδριάς ἐστι. πλάστης δὲ ἄλλος τῶν Ἀττικῶν Πολυκλῆς , Σταδιέως μαθητὴς Ἀθηναίου, πεποίηκε παῖδα Ἐφέσιον παγκρατιαστήν, Ἀμύνταν Ἑλλανίκου.
Let me also include in my account the boy whose head is bound with a ribbon, because of Pheidias and the excellence of Pheidias concerning statues, since otherwise we do not know whose image Pheidias made. Satyros, an Elean, the son of Lysianax and belonging to the family of the Iamidae, won five boxing victories at Nemea, two at Pytho, and two at Olympia; the statue is the work of the Athenian sculptor Silanion. Another Athenian sculptor, Polykles, a student of Stadieus of Athens, made a statue of an Ephesian boy, Amyntas the son of Hellanikos, a winner in the pankration.
