On the return of Cimon the popular party deemed itself sufficiently strong to manifest its opposition. The expedition to Thasos had not been attended with results so glorious as to satisfy a people pampered by a series of triumphs. Cimon was deemed culpable for not having taken advantage of the access into Macedonia, and added that country to the Athenian empire. He was even suspected and accused of receiving bribes from Alexander, the king of Macedon. Pericles [180] is said to have taken at first an active part in this prosecution; but when the cause came on, whether moved by the instances of Cimon's sister, or made aware of the injustice of the accusation, he conducted himself favourably towards the accused. Cimon himself treated the charges with a calm disdain; the result was worthy of Athens and himself. He was honourably acquitted. XIII. Scarce was this impeachment over, when a Spartan ambassador arrived at Athens to implore her assistance against the helots; the request produced a vehement discussion. Ephialtes strongly opposed the proposition to assist a city, sometimes openly, always heartily, inimical to Athens. "Much better," he contended, "to suffer her pride to be humbled, and her powers of mischief to be impaired." Ever supporting and supported by the Lacedaemonian party, whether at home or abroad, Cimon, on the other hand, maintained the necessity of marching to the relief of Sparta. "Do not," he said, almost sublimely--and his words are reported to have produced a considerable impression on that susceptible assembly-- "do not suffer Greece to be mutilated, nor deprive Athens of her companion!" The more generous and magnanimous counsel prevailed with a generous and magnanimous people; and Cimon was sent to the aid of Sparta at the head of a sufficient force. It may be observed, as a sign of the political morality of the time, that the wrongs of the helots appear to have been forgotten. But such is the curse of slavery, that it unfits its victims to be free, except by preparations and degrees. And civilization, humanity, and social order are often enlisted on the wrong side, in behalf of the oppressors, from the license and barbarity natural to the victories of the oppressed. A conflict between the negroes and the planters in modern times may not be unanalogous to that of the helots and Spartans; and it is often a fatal necessity to extirpate the very men we have maddened, by our own cruelties, to the savageness of beasts.
