Passage 10.17.1
βαρβάρων δὲ τῶν πρὸς τῇ ἑσπέρᾳ οἱ ἔχοντες Σαρδώ, εἰκόνα οὗτοι χαλκῆν τοῦ ἐπωνύμου σφίσιν ἀπέστειλαν. ἡ δὲ Σαρδὼ μέγεθος μὲν καὶ εὐδαιμονίαν ἐστὶν ὁμοία ταῖς μάλιστα ἐπαινουμέναις· ὄνομα δὲ αὐτῇ τὸ ἀρχαῖον ὅ τι μὲν ὑπὸ τῶν ἐπιχωρίων ἐγένετο οὐκ οἶδα, Ἑλλήνων δὲ οἱ κατʼ ἐμπορίαν ἐσπλέοντες Ἰχνοῦσσαν ἐκάλεσαν, ὅτι τὸ σχῆμα τῇ νήσῳ κατʼ ἴχνος μάλιστά ἐστιν ἀνθρώπου. μῆκος δὲ ἀπʼ αὐτῆς εἴκοσι στάδιοι καὶ ἑκατόν εἰσι καὶ χίλιοι, εὖρος δὲ ἐς εἴκοσί τε καὶ τετρακοσίους προήκει.
Of the barbarian peoples dwelling toward the west, those who possess Sardinia sent a bronze image of their eponymous ancestor to Olympia. Sardinia in size and prosperity resembles the most celebrated islands. Its original local name I do not know, but among the Greeks it was called by the traders who sailed there "Ichnoussa," because the shape of the island closely resembles the footprint of a human being. The length of the island extends to one thousand one hundred and twenty stadia, and its breadth reaches as far as four hundred and twenty stadia.
