Passage 8.14.6
τῷ δὲ Ὀδυσσεῖ λέγουσιν εὑρόντι τὰς ἵππους γενέσθαι οἱ κατὰ γνώμην ἐν χώρᾳ τῇ Φενεατῶν ἔχειν ἵππους, καθάπερ γε καὶ τὰς βοῦς ἐν τῇ ἠπείρῳ τῆς Ἰθάκης ἀπαντικρὺ τρέφειν αὐτόν· καί μοι καὶ γράμματα οἱ Φενεᾶται παρείχοντο ἐπὶ τοῦ ἀγάλματος γεγραμμένα τῷ βάθρῳ, τοῦ Ὀδυσσέως δή τι πρόσταγμα τοῖς ποιμαίνουσι τὰς ἵππους.
They say that when Odysseus discovered the mares, he decided it would be best to keep them in the territory of the Pheneatians, just as he pastured his cattle on the mainland opposite Ithaca. The Pheneatians even showed me an inscription upon the base of the statue, which was a certain injunction from Odysseus himself, addressed to those tending the horses.
