=140.= The influence of Cimon had greatly declined at Athens. The democratic party had recovered from its loss in Themistocles, for a new leader was arising whose popularity and services to the state were destined to eclipse even the great men who had preceded him. This was Per´icles, the son of that Xanthippus who had impeached Miltiades. His mother was niece of Clisthenes, who is called the second founder of the Athenian constitution. Born of an illustrious family, and educated in all the opportunities of Athenian camps and schools, Pericles was said to have nothing to contend against except his advantages. His beautiful face, winning manners, and musical voice reminded the oldest citizens of Pisistratus; and the vigilance with which the Athenians guarded their liberties, turned the admiration of some into jealousy. Pericles, however, made no haste to enter on his public career, but prepared himself by long and diligent study for the influence he hoped to attain. He sought the wisest teachers, and became skilled in the science of government, while he cultivated his gifts in oratory by training in all the arts of expression. Anaxag´oras, the first Greek philosopher who believed in one supreme Intelligence, creating and governing the universe, was the especial friend and instructor of Pericles, and to his sublime doctrines men attributed the elevation and purity of the young statesman’s eloquence. Instead of relying solely upon the wisdom of his counsels, like Themistocles, or upon his natural gifts, like Pisistratus, Pericles chose every word with care, and was the first who committed his orations to writing, that he might subject every sentence to the highest polish of which it was capable. The Athenian people, the most sensitive, perhaps, to beauty of style of any that ever existed, enjoyed with keen delight the clear reasoning and brilliant language which characterized the discourses of Pericles. Nor was his perfection of detail gained by any sacrifice of energy. His public speaking was compared to thunder and lightning, and he was said to carry the weapons of Zeus upon his tongue. Above all, the sweetness of his temper, and the command which philosophy had enabled him to gain over his passions, gave him advantage over less disciplined orators. The fiercest debate or the most insulting interruptions never disturbed for a moment the cheerful and dignified composure of his manner. =141.= Thasos surrendered B. C. 463; its walls were leveled, its shipping transferred to the Athenians, and all its claims upon the Thracian gold mines were given up. The people were compelled to pay all their arrears of tribute to the Delian treasury, beside engaging to meet their dues punctually in future. [Sidenote: B. C. 461.]
