Passage 7.15.11
καὶ Μεγαρεῖς μὲν παραδιδόασιν ἀμαχεὶ Ῥωμαίοις τὴν πόλιν, Μέτελλος δὲ ὡς ἀφίκετο παρὰ τὸν ἰσθμόν, ἐπεκηρυκεύετο καὶ τότε Ἀχαιοῖς ἐς εἰρήνην καὶ ὁμολογίας προκαλούμενος· ἰσχυρὸς γάρ τις ἐνέκειτο αὐτῷ πόθος τὰ ἐν Μακεδονίᾳ τε ὁμοῦ καὶ τὰ Ἀχαιῶν κατεργασθῆναι διʼ αὐτοῦ. τούτῳ μὲν ταῦτα ἐσπευκότι Δίαιος ἠναντιοῦτο ὑπὸ ἀγνωμοσύνης·
The Megarians surrendered their city to the Romans without a fight, and when Metellus arrived at the Isthmus, once more he sent envoys to the Achaeans, urging them toward peace and offering terms; for he was strongly possessed by a desire personally to bring under his own control affairs in Macedonia as well as those involving the Achaeans. Yet against this eagerness, Diaeus stubbornly opposed out of reckless obstinacy.
