When the Persians who had made themselves masters of the Chersonese, so far from quitting it, called in the people of the interior of Thrace to help them against Cimon, whom they despised for the smallness of his forces, he set upon them with only four galleys, and took thirteen of theirs; and having driven out the Persians, and subdued the Thracians, he made the whole Chersonese the property of Athens. Next he attacked the people of Thasos, who had revolted from the Athenians; and, having defeated them in a fight at sea, where he took thirty-three of their vessels, he took their town by siege, and acquired for the Athenians all the mines of gold on the opposite coast, and the territory dependent on Thasos. This opened him a fair passage into Macedon, so that he might, it was thought, have acquired a good portion of that country; and because he neglected the opportunity, he was suspected of corruption, and of having been bribed off by King Alexander. So, by the combination of his adversaries, he was accused of being false to his country. In his defence he told the judges that he had always shown himself in his public life the friend, not, like other men, of rich Ionians and Thessalians, to be courted, and to receive presents, but of the Lacedaemonians; for as he admired, so he wished to imitate, the plainness of their habits, their temperance, and simplicity of living, which he preferred to any sort of riches: but that he always had been, and still was, proud to enrich his country with the spoils of her enemies. Stesimbrotus, making mention of this trial, states that Elpinice, in behalf of her brother, addressed herself to Pericles, the most vehement of his accusers, to whom Pericles answered, with a smile, "You are old, Elpinice, to meddle with affairs of this nature."However, he proved the mildest of his prosecutors, and rose up but once all the while, almost as a matter of form, to plead against him. Cimon was acquitted.
In his public life after this he continued, whilst at home, to control and restrain the common people, who would have trampled upon the nobility. and drawn all the power and sovereignty to themselves.
But when he afterwards was sent out to war, the multitude broke loose, as it were, and overthrew all the ancient laws and customs they had hitherto observed, and, chiefly at the instigation of Ephialtes, withdrew the cognisance of almost all causes from the Areopagus; so that all jurisdiction now being transferred to them, the government was reduced to a perfect democracy, and this by the help of Pericles, who was already powerful, and had pronounced in favour of the common people. Cimon, when he returned, seeing the authority of this great council so upset, was exceedingly troubled, and endeavoured to remedy these disorders by bringing the courts of law to their former state, and restoring the old aristocracy of the time of Clisthenes. This the others declaimed against with all the vehemence possible, and began to revive those stories concerning him and his sister, and cried out against him as the partisan of the Lacedaemonians. To these calumnies the famous verses of Eupolis the poet upon Cimon refer:-"He was as good as others that one sees, But he was fond of drinking and of ease;And would at nights to Sparta often roam, Leaving his sister desolate at home."But if, though slothful and a drunkard, he could capture so many towns and gain so many victories, certainly if he had been sober and minded his business, there had been no Grecian commander, either before or after him, that could have surpassed him for exploits of war.
He was, indeed, a favourer of the Lacedaemonians, even from his youth, and he gave the names of Lacedaemonius and Eleus to two sons, twins, whom he had, as Stesimbrotus says, by a woman of Clitorium, whence Pericles often upbraided them with their mother's blood. But Diodorus the geographer asserts that both these, and another son of Cimon's, whose name was Thessalus, were born of Isodice, the daughter of Euryptolemus, the son of Megacles.
However, this is certain, that Cimon was countenanced by the Lacedaemonians in opposition to Themistocles, whom they disliked;and while he was yet very young, they endeavoured to raise and increase his credit in Athens. This the Athenians perceived at first with pleasure, and the favour the Lacedaemonians showed him was in various ways advantageous to them and their affairs; as at that time they were just rising to power, and were occupied in winning the allies to their side. So they seemed not at all offended with the honour and kindness shown to Cimon, who then had the chief management of all the affairs of Greece, and was acceptable to the Lacedaemonians, and courteous to the allies. But afterwards the Athenians, grown more powerful, when they saw Cimon so entirely devoted to the Lacedaemonians, began to be angry, for he would always in his speeches prefer them to the Athenians, and upon every occasion, when he would reprimand them for a fault, or incite them to emulation, he would exclaim, "The Lacedaemonians would not do thus." This raised the discontent, and got him in some degree the hatred of the citizens; but that which ministered chiefly to the accusation against him fell out upon the following occasion.
