Passage 7.16.1
Μόμμιος δὲ Ὀρέστην ἅμα ἀγόμενος, τὸν πρότερον ἐπὶ τῇ Λακεδαιμονίων διαφορᾷ καὶ Ἀχαιῶν ἐλθόντα, ἀφίκετο μὲν περὶ ὄρθρον ἐς τὸ τῶν Ῥωμαίων στράτευμα, ἀποπέμψας δὲ ἐς Μακεδονίαν Μέτελλον καὶ ὅσον εἵπετο ἐκείνῳ, ἀνέμενεν αὐτὸς ἐν τῷ ἰσθμῷ τὴν πᾶσαν ἀθροισθῆναι παρασκευήν. ἀφίκετο δὲ ἱππικὸν μὲν πεντακόσιοί τε καὶ τρισχίλιοι, τοῦ πεζοῦ δὲ ἀριθμὸς ἐγένετο ἐς μυριάδας δύο προσόντων καὶ τούτοις τρισχιλίων· ἐπῆλθον δὲ καὶ τοξόται Κρῆτες καὶ ἐκ Περγάμου τῆς ὑπὲρ Καΐκου Φιλοποίμην στρατιώτας ἄγων παρὰ Ἀττάλου.
Mummius, having taken with him Orestes, who had earlier come during the dispute involving the Lacedaemonians and the Achaeans, reached the camp of the Romans around dawn. Having sent forward Metellus and the forces accompanying him into Macedonia, he himself waited at the Isthmus, until his whole army had assembled. The cavalry numbered three thousand five hundred, and the infantry amounted to twenty-three thousand men; there also arrived Cretan archers and Philopoemen, who led soldiers sent by Attalus from Pergamum beyond the Caicus.
