For the next few years Demosthenes probably spent some of his time in composing private speeches for others, though the extant speeches of this period are mostly of doubtful authenticity. He also remained as a prominent figure in Athenian politics. He had not changed his views, but he seems to have been deposed from the leadership of the patriotic party by others whose patriotism was of a more violent type than his, so that he must be now counted as a moderate in opinion. It may have been this position which brought him into danger in 324 B.C. Harpalus, who had been left as Alexander’s governor at Babylon, on receipt of a rumour of his master’s death in India, made off with the royal treasure, and, accompanied by a force of six thousand men, took ship and sailed for Greece. He appeared off Piraeus, and the fervid patriots proposed that Athens should welcome him and use his treasure and his men to help them in a revolt. Demosthenes opposed an open breach with Alexander, and on his motion admission was refused to the flotilla. Harpalus came a second time without his army, and was admitted. Close on his heels came messengers from Alexander to demand his surrender, but this was resisted by Demosthenes and Phocion. On the motion of Demosthenes it was decided to temporize; Harpalus was to be treated as a prisoner, and the treasure deposited in the Parthenon. The amount of the treasure was declared by Harpalus as 720 talents, but it soon became known that only 350 talents had been lodged in the Acropolis. Harpalus in the meantime had escaped from prison and disappeared, and suspicion was roused against all who had had any kind of dealings with him. To allay the public excitement Demosthenes proposed that the Council of the Areopagus should investigate the mystery of the lost talents. Six months later the Council gave its report, issuing a list of nine public men whom it declared guilty of receiving part of the lost money. The name of Demosthenes himself headed the list; he was charged with having received twenty talents for helping Harpalus to escape. This declaration did not constitute a judicial sentence, but in consequence of it prosecutions were instituted, ten public prosecutors were appointed, and Demosthenes was found guilty. He was condemned to pay a fine of fifty talents, and being unable to raise the money he was cast into prison. He soon escaped, and fled first to Aegina and then to Troezen, where, according to Plutarch, he sat daily by the sea, watching with sad eyes the distant shores of Attica. The whole affair is obscure; we do not know how Demosthenes defended himself, but we possess two of the speeches for the prosecution, by Hyperides and Dinarchus. Neither is explicit. The report of the Areopagus was held to have established the facts, so that no further evidence was required; it was the business of the court only to interpret motives and decide the degree of each defendant’s guilt.
