=142.= A second time the Spartans asked the aid of Athens in their servile war, and Cimon again led an army to their relief. But the superiority of the Athenians in siege operations aroused the envy of the Lacedæmonians, even when employed in their defense; and the long siege of Ithome afforded time for the rivalries of the two nations to break out into open feuds. The Spartans declared that they had no further need of the Athenians, and dismissed their troops. Other allies were retained, including Ægina, the ancient rival of Athens. The latter, considering herself insulted, made an alliance with the Argives and the Aleuads of Thessaly against Sparta. The Hellenic treasury was removed from Delos to Athens, for safe keeping, it was said, against the needy and rapacious hands of the Spartans.

The favor with which he was regarded in Sparta was now his greatest crime. The Athenians had indeed some reason to fear, for the Spartan nobles always maintained a party in their city who were supposed to be secretly plotting against its free government. However honestly Cimon supported aristocratic principles, the people, with equal honesty and greater wisdom, opposed him. He was subjected to the ostracism and banished for ten years. RECAPITULATION. The power of Athens was increased by the Persian war; and her home government, which had been confined to the nobles, was thrown open to the people. Themistocles rebuilt the walls and improved the harbor. Pausanias, becoming a traitor, died of starvation in the temple of Athena, at Sparta. Athens became the chief of the Hellenic League, whose seat and treasury were at Delos. Cimon, son of Miltiades, in command of the allied forces, captured Eion, cleared Scyros of pirates, subdued rebellions in Carystus and Naxos, and conquered the Persians, both on sea and land, in the battle of the Eurymedon. He beautified Athens by a liberal use of his enormous wealth, and improved the military and naval discipline of his fellow-citizens, at the expense of their allies. Themistocles, exiled through suspicion, took refuge in the Persian dominion, where he died. Sparta suffered a double calamity, in an earthquake and a servile rebellion, known as the Third Messenian War. Her insulting treatment of her Athenian aids destroyed the popularity of Cimon; and Pericles, the most accomplished of the Athenians, rose into power. SUPREMACY OF ATHENS.
