Passage 7.9.3
Ῥωμαίων δὲ ἡ βουλὴ πέμπουσιν ἄλλους τε ἄνδρας καὶ Ἄππιον Λακεδαιμονίοις καὶ Ἀχαιοῖς τὰ δίκαια ὁρίσαι. Ἄππιος δὲ καὶ οἱ σὺν αὐτῷ ἔμελλον μὲν οὐδὲ ὀφθέντες Ἀχαιοῖς ἔσεσθαι καθʼ ἡδονήν, οἳ Ἀρέα καὶ Ἀλκιβιάδαν ἅμʼ αὐτοῖς ἐπήγοντο ἐν τῷ τότε Ἀχαιοῖς ἐχθίστους· ἐλύπησαν δὲ καὶ ἐς πλέον τοὺς Ἀχαιούς, ἐπειδὴ ἐς τὸν σύλλογον αὐτῶν ἐπελθόντες σὺν ὀργῇ μᾶλλον ἐποιοῦντο ἢ πειθοῖ τοὺς λόγους.
The Roman senate sent certain men, including Appius, to define what was just for the Lacedaemonians and Achaeans. Appius and those with him were bound to be displeasing to the Achaeans even before they appeared; for with them they brought Areus and Alcibiades, who at that time were thoroughly hateful to the Achaeans. They caused the Achaeans even greater irritation by attending their assembly and conducting their discourse harshly and with anger rather than persuasion.
