Passage 10.9.3
χαλκοῦς ταῦρος τέχνη μὲν Θεοπρόπου ἐστὶν Αἰγινήτου, Κορκυραίων δὲ ἀνάθημα. λέγεται δὲ ὡς ταῦρος ἐν τῇ Κορκύρᾳ καταλιπὼν τὰς ἄλλας βοῦς καὶ ἀπὸ τῆς νομῆς κατερχόμενος ἐμυκᾶτο ἐπὶ θαλάσσῃ· γινομένου δὲ ἐπὶ ἡμέρᾳ πάσῃ τοῦ αὐτοῦ κάτεισιν ἐπὶ θάλασσαν ὁ βουκόλος, καὶ εἶδεν ἰχθύων τῶν θύννων ἀτέκμαρτόν τι ἀριθμῷ πλῆθος.
There is a bronze bull, a work by Theopropos of Aegina, dedicated by the people of Corcyra. It is said that once, on Corcyra, a certain bull left the rest of the herd and, descending from its pasture, began to bellow toward the sea. As the same event recurred day after day, the herdsman went down to the shore and saw there an immeasurable multitude of tuna fish.
