Passage 7.13.2
Μέτελλος δὲ ἄνδρας ὑπὸ τῆς Ῥωμαίων ἀπεσταλμένους βουλῆς ἐπὶ τὰ ἐν τῇ Ἀσίᾳ πράγματα ἐκέλευε, πρὶν ἢ ἐς τὴν Ἀσίαν διαβῆναι, τοῖς ἡγεμόσιν αὐτοὺς τοῖς Ἀχαιῶν ἐς λόγους ἐλθεῖν, ὅπλα μὲν ἐπὶ τὴν Σπάρτην μὴ ἐπιφέρειν σφίσιν ἀπαγορεύσοντας, τὴν δὲ ἐκ Ῥώμης παρουσίαν τῶν ἀνδρῶν προεροῦντας μένειν, οἳ κατὰ τοῦτο ἦσαν ἀπεσταλμένοι Λακεδαιμονίοις δικασταὶ καὶ Ἀχαιοῖς γενέσθαι.
Metellus ordered men who had been sent by the Roman senate regarding affairs in Asia, before crossing over to Asia, to enter into discussions with the generals of the Achaeans, forbidding them from taking arms against Sparta, and declaring beforehand to them that they should await the arrival of men coming from Rome, who had been dispatched thus to serve as arbitrators between the Lacedaemonians and the Achaeans.
