Soon after this the Samian war broke out, in which Pericles gained high renown as a naval commander. This war originated in a quarrel between Miletus and the island of Samos, in which Athens was led to take part with the former. The Samians, after an obstinate struggle, were beaten, and a peace was concluded (439). The position in which Athens then stood toward many of the Greek states was peculiar. Since the time of the Persian invasion, she had been the leader of the confederacy formed to resist the attacks of the powerful enemy, and the guardian of the confederate treasury kept in the isle of Delos. Pericles caused the treasury to be removed to Athens, and commuting the contingents of the allies for money, enormously increased the contributions to the patriotic fund, Athens herself undertaking to protect the confederacy. The grand charge against Pericles is that he applied the money thus obtained to other purposes than those for which it was designed; that, in short, he adorned and enriched Athens with the spoils of the allied states. To his mind Hellas was subordinate to Athens, and he confounded the splendor of the dominant city with the splendor of Greece, in a manner possible to a man of poetic imagination, hardly to a man of the highest honor. His enemies, who dared not attack himself, struck at him in the persons of his friends. Phidias was flung into prison for the impiety of introducing portraits of himself and Pericles into the battle of the Amazons depicted on the shield of the goddess Athena in the Parthenon; the brilliant Aspasia, the famous mistress of Pericles, was arraigned on a charge of impiety, and only acquitted through the eloquence of Pericles on her behalf; while the aged Anaxagoras was driven from the city. It is unnecessary to give a detailed account of all that Pericles did to make his native city the most glorious in the ancient world. Greek architecture and sculpture under his patronage reached perfection. To him Athens owed the Parthenon, the Erechtheum, left unfinished at his death, the Propylaea, the Odeum, and numberless other public and sacred edifices; he also liberally encouraged music and the drama; and during his life, industry and commerce were in so flourishing a condition that prosperity was universal in Attica.
