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.
143. Athens, under the lead of Pericles, now entered upon the most brilliant period of her history. A dispute between Megara and Corinth involved Athens on the former and Sparta on the latter side, and thus led to the First Peloponnesian War (B. C. 460-457). At the same time, a more distant enterprise tempted the Athenians. Egypt had now cast off the last semblance of obedience to Persia, and hailed a deliverer and sovereign in the person of Inarus. In looking about him for allies, Inarus naturally sought the aid of those who, at Marathon, had first broken the power of the Persians. The Athenians engaged gladly in the war, and sent a fleet of two hundred triremes to the Nile. The events of the campaign have been recorded in the History of Persia.[48]
B. C. 457.
144. The war in Greece went on with great vigor. The Athenians were defeated at Halæ, but soon after won a naval battle at Cec´ryphali´a,[49] which more than retrieved their reputation. Ægina now joined in the war, and the Athenians landed upon the island and besieged the city. A Peloponnesian army came to the aid of Ægina, while the Corinthians seized the opportunity to invade Megaris. With all her forces employed either in Egypt or Ægina, they hoped that Athens would be overcome by this new attack. But Myron´ides mustered an army of boys and old men exempt from service, and marched at once to the assistance of Megara. In the battle which ensued, neither party acknowledged itself defeated, but the Corinthians withdrew to their capital, while the Athenians held the field and erected a trophy. Unable to bear the reproaches of their government, the Corinthian army returned after twelve days and raised a monument upon the field, claiming that the victory had been theirs. But the Athenians now attacked them anew, and inflicted a decisive and disgraceful defeat.
145. In the midst of these enterprises abroad, great public works were going on in Athens. Cimon had already planned a line of fortifications to unite the city with its ports, and the spoils of the Persians, taken at the Eurymedon and at Cyprus, had been assigned for the expense. Under the direction of Pericles, the building began in earnest. One wall was extended to Phalerum, and another to Piræus; but as it was found difficult to defend so large an inclosed space, a second wall to Piræus was added, at a distance of 550 feet from the first. Between these Long Walls a continuous line of dwellings bordered the carriage-road, nearly five miles in length, which extended from Athens to its principal harbor.
146. The Spartans were still too much absorbed in the siege of Ithome to interfere with the great and sudden advancement of Athenian power; but a disaster which befell their little ancestral land of Doris, in war with the Phocians, withdrew their attention even from their own troubles. An army of 1,500 heavy-armed Spartans and 10,000 auxiliaries, sent to the relief of the Dorians, drove the Phocians from the town they had taken, and secured their future good behavior by a treaty. The retreat of the Spartans was now cut off by the Athenian fleet in the Gulf of Corinth and the garrison in the Megarid. Their commander, Nicome´des, had, however, reasons beyond the necessity of the case for remaining a while in Bœotia. He was plotting with the aristocratic party in Athens for the return of Cimon, and he also desired to increase the power of Thebes, as a near and dangerous rival to the former city.
B. C. 457.
The conspiracy becoming known, the Athenians were roused to revenge. They raised an army of 14,000 men and marched against Nicomedes, at Tan´agra. Both sides fought with equal bravery and skill, and the victory was undecided until the Thessalian cavalry deserted to the Spartans. The Athenians and their allies still held out for some hours, but when the contest ended with the daylight, the victory remained with their adversaries. Nicomedes reaped no other fruit from his victory than a safe return home, but Thebes gained from it an increase of power over the cities of Bœotia.
