Passage 5.24.8
καὶ τὰ ἀναθήματα ἀνέθεσαν ἐν Ὀλυμπίᾳ τῷ Διὶ οἱ ἐνταῦθα οἰκοῦντες, ὡς εἰ τῆς Ἐφεσίων πόλεως οἱ ἔχοντες τὸν ὀνομαζόμενον Κόρησον ἀνάθημα φαῖεν ἰδίᾳ τι ἀναθεῖναι τοῦ Ἐφεσίων κοινοῦ. ἔστι δὲ καὶ πρὸς τῷ τείχει τῆς Ἄλτεως Ζεὺς ἐπὶ ἡλίου τετραμμένος δυσμάς, ἐπίγραμμα οὐδὲν παρεχόμενος· ἐλέγετο δὲ καὶ οὗτος Μομμίου τε καὶ ἀπὸ τοῦ Ἀχαιῶν εἶναι πολέμου.
And the inhabitants there dedicated offerings to Zeus at Olympia; just as if certain men possessing the so-called sanctuary of Koresos in the city of the Ephesians were to claim that their dedication was something private, distinct from the common dedication of all the Ephesians. Also, near the wall of the Altis stands a Zeus statue facing toward the sunset; it bears no inscription, but this too was said to be an offering by Mummius and from the war against the Achaeans.
