The ill success of the expedition of Cimon gave Pericles the opportunity to place himself and the popular party in power at Athens; for the constitutional reforms that had been gradually weakening the power of the aristocracy were now made available to sweep it almost entirely away. The following extract from BULWER'S Athens briefly yet fully tells what was accomplished in this direction:

"The Constitution previous to Solon was an oligarchy of birth. Solon rendered it an aristocracy of property. Clisthenes widened its basis from property to population; and it was also Clisthenes, in all probability, who weakened the more illicit and oppressive influences of wealth by establishing the ballot of secret suffrage, instead of the open voting which was common in the time of Solon. The Areop'agus was designed by Solon as the aristocratic balance to the popular assembly. This constitutional bulwark of the aristocratic party of Athens became more and more invidious to the people, and when Cimon resisted every innovation on that assembly he only insured his own destruction, while he expedited the policy he denounced. Ephial'tes, the friend and spokesman of Pericles, directed all the force of the popular opinion against this venerable senate; and at length, though not openly assisted by Pericles, who took no prominent part in the contention, that influential statesman succeeded in crippling its functions and limiting its authority."

With regard to the nature of the constitutional changes effected, the same writer adds: "It appears to me most probable that the Areopagus retained the right of adjudging cases of homicide, and little besides of its ancient constitutional authority; that it lost altogether its most dangerous power in the indefinite police it had formerly exercised over the habits and morals of the people; that any control of the finances was wisely transferred to the popular senate; that its irresponsible character was abolished, and that it was henceforth rendered accountable to the people." The struggle between the contending parties was long and bitter, and the fall of Cimon was one of the necessary consequences of the political change. Charged, among other things, with too great friendship for Sparta, he was driven into exile. Pericles now persuaded the Athenians to renounce the alliance with Sparta, and he increased the power of Athens by alliances with Argos and other cities. He also continued the construction of the long walls from Athens to the Piræus and Phalerum—a project that Themistocles had advised and that Cimon had commenced.

The long existing jealousy of Sparta at last broke out in open hostilities. While the siege of Ithome was in progress, Sparta, still powerful in her alliances, sent her allied forces into Bœotia to counteract the growing influence of the Athenians in that quarter. The indignant Athenians, led by Pericles, marched out to meet them, but were worsted in the battle of Tan'agra. Before this conflict began, Cimon, the banished commander, appeared in the Athenian camp and begged permission to enter the ranks against the enemy. His request being refused, he left his armor with his friends, of whom there were one hundred among the Athenians, with the charge to refute, by their valor, the accusation that he and they were the friends of Sparta. Everyone of the one hundred fell in the conflict. About two months after, in the early part of the year 456 B.C., the Athenians wiped off the stain of their defeat at Tanagra by a victory over the combined Theban and Bœotian forces, then in alliance with Sparta; whereby the authority and influence of Sparta were again confined to the Peloponnesus.

The Athenians were now masters of Greece, from the Gulf of Corinth to the Pass of Thermopylæ, and in the following year they sent an expedition round the Peloponnesus, which captured, among other cities, Naupactus, on the Corinthian Gulf. The third and last Messenian war had just been concluded by the surrender of Ithome, on terms which permitted the Messenians and their families to retire from the Peloponnesus, and they joined the colony which Athens planted at Naupactus. But the successes of Athens in Greece were counterbalanced, in the same year, by reverses in Egypt, where the Athenians were fighting Persia in aid of In'arus, a Libyan prince. These, with some other minor disasters, and the state of bitter feeling that existed between the two parties at Athens, induced Pericles to recall Cimon from exile and put him in command of an expedition against Cyprus and Egypt. In 449, however, Cimon was taken ill, and he died in the harbor of Ci'tium, to which place he was laying siege.

Before the death of Cimon, and through his intervention, a five years' truce had been concluded with Sparta, and soon after his death peace was made with Persia. From this time the empire of Athens began to decline. In the year 447 B.C. a revolt in Bœotia resulted in the overthrow of Athenian supremacy there, while the expulsion of the Athenians from Pho'cis and Lo'cris, and the revolt of Euboea and Megara, followed soon after. The revolt of Euboea was soon quelled, but this was the only success that Athens achieved. Meanwhile a Spartan army invaded Attica and marched to the neighborhood of Eleusis. Having lost much of her empire, with a fair prospect of losing all of it if hostilities continued, Athens concluded a thirty years' truce with Sparta and her allies, by the terms of which she abandoned her conquests in the Peloponnesus, and Megara became an ally of Sparta (445 B.C.)

THE "AGE OF PERICLES."

With the close of the Persian contest, and the beginning of the Thirty Years' truce, properly begins what has been termed the "Age of Pericles"—the inauguration of a new and important era of Athenian greatness and renown. Having won the highest military honors and political ascendancy, Athens now took the lead in intellectual progress. Themistocles and Cimon had restored to Athens all that of which Xerxes had despoiled it—the former having rebuilt its ruins, and the latter having given to its public buildings a degree of magnificence previously unknown. But Pericles surpassed them both:

He was the ruler of the land
When Athens was the land of fame;
He was the light that led the band
When each was like a living flame;
The centre of earth's noblest ring,
Of more than men the more than king.

Yet not by fetter nor by spear
His sovereignty was held or won:
Feared—but alone as freemen fear;
Loved—but as freemen love alone;
He waved the sceptre o'er his kind
By nature's first great title—mind!
—CROLY.
