Passage 5.20.8
ἀνὴρ βουλῆς τῆς Ῥωμαίων ἀνείλετο Ὀλυμπικὴν νίκην· ἐθέλων δὲ ὑπολιπέσθαι τῆς νίκης ὑπόμνημα χαλκῆν εἰκόνα σὺν ἐπιγράμματι, ὤρυσσεν ἐς ποίησιν βάθρου· καὶ ὡς ἐγένετο ἐγγύτατα τὸ ὄρυγμα αὐτῷ τῆς τοῦ Οἰνομάου κίονος, ἐνταῦθα εὕρισκον οἱ ὀρύσσοντες καὶ ὅπλων καὶ χαλινῶν καὶ ψαλίων θραύματα.
A man from the Roman senate gained an Olympic victory. Wishing to leave behind a memorial of his victory, a bronze statue with an inscription, he proceeded to dig to construct a base. When the excavation had come very close to the pillar of Oenomaus, those digging discovered fragments of armor, bridles, and horse-bits.
