Passage 5.10.5
τοῦ δὲ ἐν Ὀλυμπίᾳ ναοῦ τῆς ὑπὲρ τῶν κιόνων περιθεούσης ζώνης κατὰ τὸ ἐκτὸς ἀσπίδες εἰσὶν ἐπίχρυσοι μία καὶ εἴκοσιν ἀριθμόν, ἀνάθημα στρατηγοῦ Ῥωμαίων Μομμίου κρατήσαντος Ἀχαιῶν πολέμῳ καὶ Κόρινθόν τε ἑλόντος καὶ Κορινθίους τοὺς Δωριέας ποιήσαντος ἀναστάτους.
On the temple at Olympia, around the outside of the band that runs above the columns, there are twenty-one gilded shields—these are an offering of the Roman general Mummius, who defeated the Achaeans in war, captured Corinth and utterly destroyed the Dorian inhabitants of Corinth.
