Passage 6.16.9
ἐφεξῆς δὲ Πτολεμαῖός τέ ἐστιν ἀναβεβηκὼς ἵππον καὶ παρʼ αὐτὸν Ἠλεῖος ἀθλητὴς Παιάνιος ὁ Δαματρίου πάλης τε ἐν Ὀλυμπίᾳ καὶ τὰς δύο Πυθικὰς ἀνῃρημένος νίκας. Κλεάρετός τέ ἐστιν Ἠλεῖος πεντάθλου λαβὼν στέφανον καὶ ἅρμα ἀνδρὸς Ἀθηναίου Γλαύκωνος τοῦ Ἐτεοκλέους· ἀνηγορεύθη δὲ ὁ Γλαύκων οὗτος ἐπὶ ἅρματος τελείου δρόμῳ.
Next in order stands Ptolemaeus mounted upon a horse, and beside him, Paeanios of Elis, the son of Dematrius, an athlete who won victories in wrestling at Olympia as well as two victories at the Pythian Games. There is also Klearetos of Elis, crowned for victory in the pentathlon, and the chariot belonging to Glaukon, the son of Eteokles, an Athenian. This Glaukon was proclaimed victor in the race for fully-grown horses.
