Passage 6.10.8
τῶν δὲ ἱπποτροφησάντων ἐν Ἕλλησι πρῶτος ἐς Ὀλυμπίαν εἰκόνα ἀνέθηκεν ὁ Κλεοσθένης οὗτος. τὰ γὰρ Μιλτιάδου τοῦ Ἀθηναίου καὶ Εὐαγόρου τοῦ Λάκωνος ἀναθήματα, τοῦ μὲν ἅρματά ἐστιν, οὐ μὴν καὶ αὐτὸς ἐπὶ τοῖς ἅρμασιν Εὐαγόρας· τὰ Μιλτιάδου δέ, ὁποῖα ἐς Ὀλυμπίαν ἀνέθηκεν, ἑτέρωθι δὴ δηλώσω τοῦ λόγου. Ἐπιδάμνιοι δὲ χώραν μὲν ἥνπερ καὶ ἐξ ἀρχῆς, πόλιν δὲ οὐ τὴν ἀρχαίαν ἐπὶ ἡμῶν ἔχουσιν, ἐκείνης δὲ ἀφεστηκυῖαν ὀλίγον· ὄνομα δὲ τῇ πόλει τῇ νῦν Δυρράχιον ἀπὸ τοῦ οἰκιστοῦ.
Of those among the Greeks who bred horses, Cleosthenes was the first to set up an image at Olympia. For although there are dedications of Miltiades the Athenian and Evagoras the Lakonian, Evagoras dedicated chariots, but he himself is not depicted upon them; concerning the dedications of Miltiades, I will make clear elsewhere in my account exactly what he set up at Olympia. The Epidamnians still possess the countryside they originally inhabited, but in our time their city is not the ancient one; rather, it has shifted slightly away from its original site and is now called Dyrrhachium, named after its founder.
