Passage 5.27.9
βοῶν δὲ τῶν χαλκῶν ὁ μὲν Κορκυραίων, ὁ δὲ ἀνάθημα Ἐρετριέων, τέχνη δὲ Ἐρετριέως ἐστὶ Φιλησίου · καὶ ἀνθʼ ὅτου μὲν οἱ Κορκυραῖοι τόν τε ἐν Ὀλυμπίᾳ καὶ ἕτερον βοῦν ἐς Δελφοὺς ἀνέθεσαν, δηλώσει μοι τὰ ἐς Φωκέας τοῦ λόγου, ἐπὶ δὲ τῷ Ὀλυμπίασιν αὐτῶν ἀναθήματι συμβῆναι τοιόνδε ἤκουσα.
Of the bronze oxen, one was dedicated by the Corcyraeans, and the other is an offering of the Eretrians, wrought by Philesius of Eretria. Concerning the reason for which the Corcyraeans dedicated the ox at Olympia and another ox at Delphi, my account of the Phocaeans will make clear. But I have heard the following story about what happened concerning their dedication at Olympia.
