τὸ δὲ ἀπὸ ἄκρας Ἰαπυγίας ἐπὶ τὸν μυχὸν τοῦ Κορινθιακοῦ κόλπου τῶν μὲν τρισχιλίων ἐστὶν ἔλαττον, τὸ δ᾽ ἀπὸ Ἰαπυγίας εἰς τὴν Λιβύην πλέον τῶν τετρακισχιλίων ἐστί. νῆσοι δ᾽ εἰσὶν ἐνταῦθα ἥ τε Κόρκυρα καὶ Σύβοτα πρὸ τῆς Ἠπειρώτιδος, καὶ ἐφεξῆς πρὸ τοῦ Κορινθιακοῦ κόλπου Κεφαλληνία καὶ Ἰθάκη καὶ Ζάκυνθος καὶ Ἐχινάδες.
And the stretch from the lapygian Cape to the head of the Gulf of Corinth is less than three thousand stadia, while that from Iapygia to Libya is more than four thousand. The islands of this sea are: Corcyra and the Sybota off the coast of Epirus; and next to them, off the Gulf of Corinth, Cephallenia, Ithaca, Zacynthus, and the Echinades.
