Passage 10.34.5
τὸ δὲ Κοστοβώκων τε τῶν λῃστικῶν τὸ κατʼ ἐμὲ τὴν Ἑλλάδα ἐπιδραμὸν ἀφίκετο καὶ ἐπὶ τὴν Ἐλάτειαν· ἔνθα δὴ ἀνὴρ Μνησίβουλος λόχον τε περὶ αὑτὸν ἀνδρῶν συνέστησε καὶ καταφονεύσας πολλοὺς τῶν βαρβάρων ἔπεσεν ἐν τῇ μάχῃ. οὗτος ὁ Μνησίβουλος δρόμου νίκας καὶ ἄλλας ἀνείλετο καὶ Ὀλυμπιάδι πέμπτῃ πρὸς ταῖς τριάκοντά τε καὶ διακοσίαις σταδίου καὶ τοῦ σὺν τῇ ἀσπίδι διαύλου· ἐν Ἐλατείᾳ δὲ κατὰ τὴν ὁδὸν τοῦ δρομέως Μνησιβούλου χαλκοῦς ἕστηκεν ἀνδριάς.
In my own time, the marauding tribe of the Costoboci made a raid into Greece, reaching as far as Elateia. Here, a man named Mnesiboulos gathered about himself a company of men, slew many of the barbarians, and fell himself during the battle. This Mnesiboulos had previously won victories in running and other contests, winning in the two-hundred-and-thirty-fifth Olympiad both the stadium and the race in armour. At Elateia, there stands by the road a bronze statue of the runner Mnesiboulos.
