Miletus, demanding the arrears of tribute. So urgent was the need supplied by the energy of Athens, and so blind were these Greeks of Asia Minor to their own interests.
The visible sign of this momentous change, by which the Delian Confederacy became merged in the Athenian Empire, was the removal of the treasury from Delos to Athens. The Athenians now undertook the whole administration of the common fund, using the surplus for the adornment of Athens by magnificent public buildings. This appropriation seems reasonable enough, when we consider that the whole burden of defending the eastern Greeks against Persia, and keeping the barbarian out of Greek waters, now lay upon Athens. This great public duty, which had been thrown upon her by the indifference of Sparta, and the unmanly sloth of her own allies, was faithfully performed; and she might well ask why she should be called upon to lavish the blood of her own citizens for nothing. That Athens should be great, splendid, and powerful, was not only a reward due to her public spirit and devotion to the common cause, but also a guarantee for the general dignity and liberty of Greeks. And we, who have still before us the remnants of her temples and statues, and learn from them what man can accomplish under the inspiration of great ideals, need not scan too closely her claim to appropriate the funds which she employed for so noble a purpose. For this was the great age of Grecian art, the age of Phidias, Polycletus, Myron, and Polygnotus. The greatest of these was Phidias; and in the Parthenon, or Temple of the Virgin Goddess, [Footnote: Athene, the patron goddess of Athens.] built under his direction on the Acropolis at Athens, he has left the most enduring monument of his fame. He also designed the Propylaea, a magnificent columned vestibule, fronting the broad flight of steps which led up to the western entrance of the Acropolis. But the most renowned of his works was the gigantic statue of the Olympian Zeus, wrought in gold and ivory, which was the chief glory of the temple at Olympia. Of this sublime creation, the highest expression of divinity achieved by the ancients, only the fame survives. These triumphs of art were not brought to completion until nearly the close of the period of forty-eight years which separates the Persian from the Peloponnesian War; and it is now necessary to glance backward, and touch briefly on the principal events which occurred after the formation of the Delian Confederacy. The war was carried on with energy against Persia, and hostilities continued at intervals for thirty years after the battle of Plataea. [Footnote: B.C. 479-449.]
The chief leader in these enterprises was the heroic Cimon, leader of the conservative party at Athens, and the great rival of Pericles; and his most brilliant exploit was a crushing defeat inflicted on the Persian army and fleet at the mouth of the river Eurymedon in Pamphylia. But the victorious career of the Athenians received a severe check twelve years later in Egypt, where a large force of ships and men was totally destroyed by the Persian general Megabyzus. The war dragged on for five years longer, and peace was then concluded on terms highly advantageous to the Greeks. Shortly before this, Cimon, who had been the chief promoter of the war, died at Cyprus.
