So when Alexander went back to Macedonia, Demades and his associates were high in power, but Demosthenes acted a humble part. It is true that when Agis the Spartan was active in revolt Demosthenes once more made a feeble effort in his support, but then he cowered down, since the Athenians would not join in the uprising. Agis fell in battle, and the Lacedaemonians were crushed. It was at this time that the indictment against Ctesiphon in the matter of the crown came on for trial. It had been prepared in the archonship of Chaerondas a little before the battle of Chaeroneia, but came on for trial ten years later in the archonship of Aristophon. It became the most celebrated of all public causes, not only on account of the fame of the orators, but also because of the noble conduct of the judges, who, though the prosecutors of Demosthenes were then at the height of power and acting in the interests of Macedonia, would not vote against him, but acquitted him so decisively that Aeschines did not get a fifth part of their ballots. Consequently, Aeschines forsook the city at once, and spent the rest of his life as a teacher of rhetoric in Rhodes and Ionia.
