Strabo Geography 13.1.66

[66] Both Assus and Adramyttium are notable cities. But misfortune befell Adramyttium in the Mithridatic War, for the members of the city council were slaughtered, to please the king, by Diodorus ¹ the general, who pretended at the same time to be a philosopher of the Academy, a dispenser of justice, and a teacher of rhetoric. And indeed he also joined the king on his journey to Pontus; but when the king was overthrown he paid the penalty for his misdeeds; for many charges were brought against him, all at the same time, and, being unable to bear the ignominy, he shamefully starved himself to death, in my own city. Another inhabitant of Adramyttium was the famous orator Xenocles, ² who belonged to the Asiatic school and was as able a debater a ever lived, having even made a speech on behalf of Asia before the Senate, ³ at the time when Asia was accused of Mithridatism.

[66] Assus and Adramyttium are considerable cities. Adramyttium was unfortunate in the Mithridatic war, for Diodorus the general, in order to gratify the king, put to death the council of the citizens, although at the same time he pretended to be a philosopher of the Academy, pleaded causes, and professed to teach rhetoric. He accompanied the king on his voyage to Pontus, but upon his overthrow Diodorus was punished for his crimes. Many accusations were simultaneously preferred against him: but, unable to endure disgrace, he basely destroyed himself in my native city by abstaining from food.

Adramyttium produced Xenocles, a distinguished orator, who adopted the Asiatic style of eloquence and was remarkable for the vehemence of his manner; he defended Asia before the senate, at the time when that province was accused of favouring the party of Mithridates.
