Passage 6.10.7
ἐπιγέγραπται δὲ καὶ τῶν ἵππων τὰ ὀνόματα Φοῖνιξ καὶ Κόραξ, ἑκατέρωθεν δὲ οἱ παρὰ τὸ ζυγόν, κατὰ μὲν τὰ δεξιὰ Κνακίας, ἐν δὲ τῇ ἀριστερᾷ Σάμος· καὶ ἐλεγεῖον τόδε ἐστὶν ἐπὶ τῷ ἅρματι· Κλεοσθένης μʼ ἀνέθηκεν ὁ Πόντιος ἐξ Ἐπιδάμνου, νικήσας ἵπποις καλὸν ἀγῶνα Διός.
The names of the horses are also inscribed: Phoenix and Korax, while those beside the yoke on either side are Knakias on the right and Samos on the left. And this elegiac couplet is written upon the chariot: "Cleosthenes of Epidamnus on the Pontus dedicated me, having won a glorious contest of Zeus with his horses."
