Passage 7.14.5
ὡς δὲ οὐκ ἀφίκοντο οἱ συνεδρεύσοντες, ἐνταῦθα ὁ Κριτόλαος μάλιστα ἐπεδείκνυτο ἀπάτῃ πρὸς Ῥωμαίους χρώμενος, ὃς ἄλλην ἐκέλευεν ἀναμένειν αὐτοὺς Ἀχαιῶν σύνοδον, ἐς μῆνα ἐσομένην ἕκτον· αὐτὸς δὲ οὐδὲν ἰδίᾳ διαλέξεσθαί σφισιν ἄνευ τοῦ κοινοῦ τοῦ Ἀχαιῶν ἔφασκε. καὶ οἱ μὲν ἐπεὶ ἀπατώμενοι συνῆκαν, ἀπηλλάσσοντο ἐς Ῥώμην· Κριτόλαος δὲ ἐς Κόρινθον Ἀχαιοὺς ἀθροίσας ἀνέπεισε μὲν ἐπιφέρειν ὅπλα ἐπὶ τὴν Σπάρτην, ἀνέπεισε δὲ καὶ Ῥωμαίοις ἐκ τοῦ εὐθέος πόλεμον ἄρασθαι.
But when those delegates who were to attend the conference did not arrive, Critolaus especially displayed his deceit toward the Romans. He urged them to await another meeting of the Achaeans, which would take place in six months, asserting that he himself would not privately negotiate any matter with them apart from the common consent of the Achaeans. When they finally realized they had been deceived, the Romans departed to Rome. Critolaus, however, assembling the Achaeans at Corinth, persuaded them first to take up arms against Sparta and, afterward, convinced them to declare immediate war against the Romans.
