In 415, on the eve of the sailing of the Sicilian expedition, Athens was startled and horrified by a remarkable act of sacrilege. The images of Hermes which stood everywhere in the town were, all but one, mutilated and defaced in a single night. The superstitious citizens, with a deep feeling that the whole community must suffer for the guilty action of some of its members, considered this an evil omen for the fortunes of the Syracusan expedition, and, less reasonably, took it as an indication of impending revolution and an attempt to subvert the democracy. Their anxiety was increased by rumours that a profane parody of the Eleusinian mysteries was being celebrated in certain private houses. Such acts of impiety were likely to bring upon Athens the wrath of the gods who had hitherto protected her. It will be remembered how Alcibiades, one of the leaders of the expedition, was accused of complicity in the plot, and how this accusation brought about his recall from Sicily and his estrangement from his native city, which led to the utter failure of the great enterprise of conquest, and ultimately, through the total loss of her best armies and fleets, to the downfall of Athens herself. Andocides was accused of complicity both in the profanation of the mysteries and the mutilation of the Hermae. Of the former charge he apparently succeeded in clearing himself, but he confesses to a knowledge of the affair of the Hermae. A certain Teucrus denounced eighteen persons as guilty of the mutilation of the busts. Of these some were put to death, the rest went into exile. The list included some members of the club to which Andocides belonged. Another informer, Dioclides, came forward with a tale that about three hundred persons were implicated, and he named forty-two of them, including Andocides and twelve of his near relations. Athens was in a panic, and eager for instant vengeance. The informers’ victims were at once imprisoned, and their situation was grave indeed. Andocides describes how, to save his father and other innocent persons, he at last resolved to tell what he knew. He gave his information under a promise of immunity from punishment, but in accordance with the terms of a subsequent decree he suffered ‘_atimia_,’ comprising exclusion from the market-place and the temples; and being thus debarred from a public career he decided to go abroad. In the _de Reditu_, delivered in 410 B.C., five years after the outrage, Andocides implies that he was himself concerned in the deed, and asks pardon for his ‘youthful folly’ (§ 7). The language of Thucydides[92] and others also implies that he accused himself along with others. The language of the _de Reditu_ is not, however, explicit, and does not necessarily disagree with the statement made twelve years later in the _de Mysteriis_.
