Passage 7.14.4
Διαίῳ δὲ ἐξήκοντος τοῦ χρόνου τῆς ἀρχῆς στρατηγεῖν ὑπὸ Ἀχαιῶν ᾑρέθη Κριτόλαος. τοῦτον δριμὺς καὶ σὺν οὐδενὶ λογισμῷ τὸν Κριτόλαον πολεμεῖν πρὸς Ῥωμαίους ἔρως ἔσχε· καὶ---ἔτυχον γὰρ τότε ἤδη οἱ παρὰ Ῥωμαίων ἥκοντες τὰ Λακεδαιμονίων καὶ Ἀχαιῶν δικάσαι---ἀφίκετο μὲν ἐν Τεγέᾳ τῇ Ἀρκάδων τοῖς ἀνδράσιν ἐς λόγους ὁ Κριτόλαος, ἀθροῖσαι δὲ Ἀχαιούς σφισιν ἐς κοινὸν σύλλογον οὐδαμῶς ἤθελεν, ἀλλὰ ἐς μὲν ἐπήκοον τῶν Ῥωμαίων ἔπεμπεν ἀγγέλους κελεύων τοὺς συνέδρους καλεῖν ἐς τὸ Ἀχαϊκόν, ἰδίᾳ δὲ τοῖς συνέδροις ἐπέστελλεν ἐς τὰς πόλεις ἀπολείπεσθαι σφᾶς τοῦ συλλόγου.
When Diaeus' term of office expired, Critolaus was chosen by the Achaeans to succeed him as general. Critolaus was seized by a bitter and utterly rash passion to wage war upon the Romans. For at this very moment the delegates sent from Rome had already arrived to arbitrate the dispute between the Spartans and the Achaeans. Critolaus went to Tegea in Arcadia and spoke before the people there, yet he absolutely refused to gather the Achaeans into a common assembly with the Roman representatives. Instead, in the hearing of the Romans, he sent messengers ordering the delegates to convene at the Achaean assembly, but privately dispatched instructions to these delegates, telling them to remain in their own cities and not assemble.
