The first indication of the unpopularity which he had incurred is the attack made upon him by Aristophanes in the 'Clouds' in the year 423 B.C. That attack, however, seems to have evaporated with the laugh, and for many years Socrates continued his teaching without molestation. It was not till B.C. 399 that the indictment was preferred against him which cost him his life. In that year, Meletus, a leather-seller, seconded by Anytus, a poet, and Lycon, a rhetor, accused him of impiety in not worshipping the gods of the city, and in introducing new deities, and also of being a corrupter of youth. With respect to the latter charge, his former intimacy with Alcibiades and Critias may have, weighed against him. Socrates made no preparations for his defence, and seems, indeed, not to have desired an acquittal. But although he addressed the dicasts in a bold uncompromising tone, he was condemned only by a small majority of five or six in a court composed of between five and six hundred dicasts. After the verdict was pronounced, he was entitled, according to the practice of the Athenian courts, to make some counter-proposition in place of the penalty of death, which the accusers had demanded, and if he had done so with any show of submission it is probable that the sentence would have been mitigated. But his tone after the verdict was higher than before. Instead of a fine, he asserted that he ought to be maintained in the Prytaneum at the public expense, as a public benefactor. This seems to have enraged the dicasts and he was condemned to death. It happened that the vessel which proceeded to Delos on the annual deputation to the festival had sailed the day before his condemnation; and during its absence it was unlawful to put any one to death. Socrates was thus kept in prison during thirty days, till the return of the vessel. He spent the interval in philosophical conversations with his friends. Crito, one of these, arranged a scheme for his escape by bribing the gaoler; but Socrates, as might be expected from the tone of his defence, resolutely refused to save his life by a breach of the law. His last discourse, on the day of his death, turned on the immortality of the soul. With a firm and cheerful countenance he drank the cup of hemlock amidst his sorrowing and weeping friends. His last words were addressed to Crito:--"Crito, we owe a cock to AEsculapius; discharge the debt, and by no means omit it." Thus perished the greatest and most original of the Grecian philosophers, whose uninspired wisdom made the nearest approach to the divine morality of the Gospel. His teaching forms an epoch in the history of philosophy. From his school sprang Plato, the founder of the Academic philosophy; Euclides, the founder of the Megaric school; Aristippus, the founder of the Cyrenaic school; and many other philosophers of eminence.
