Passage 6.15.10
ὅτῳ δὲ παρεστήκασιν οἱ παῖδες, τοῦτον μὲν Πτολεμαῖον τὸν Λάγου φασὶν εἶναι· παρὰ δὲ αὐτὸν ἀνδριάντες δύο ἀνδρός εἰσιν Ἠλείου Κάπρου τοῦ Πυθαγόρου, πάλης τε εἰληφότος καὶ παγκρατίου στέφανον ἐπὶ ἡμέρας τῆς αὐτῆς· πρώτῳ δὲ γεγόνασιν ἀνθρώπων αἱ δύο νῖκαι τῷ Κάπρῳ τούτῳ. τὸν μὲν δὴ ἐπὶ τοῦ παγκρατίου καταγωνισθέντα ὑπʼ αὐτοῦ δεδήλωκεν δὲ ὁ λόγος ἤδη μοι· παλαίων δὲ κατέβαλεν Ἠλεῖον Παιάνιον Ὀλυμπιάδα πάλῃ τὴν προτέραν ἀνῃρημένον καὶ Πύθια παίδων τε πυγμῇ καὶ αὖθις ἐν ἀνδράσι πάλῃ τε καὶ πυγμῇ στεφανωθέντα ἐπὶ ἡμέρας τῆς αὐτῆς.
The statue by which the children are standing is said to represent Ptolemy, son of Lagus. Beside him are two statues of Caprus, son of Pythagoras, an Elean who gained victories in wrestling and pancratium on the very same day—these two victories of Caprus being the first ever achieved by any man. I have already described the opponent whom he defeated in pancratium; in wrestling he overcame Paeanios, an Elean who had previously won an Olympic victory in wrestling, and at the Pythian games had gained crowns first in boys' boxing, and again later, on the same day, in the men's competitions both for wrestling and boxing.
