Her great political, dramatist speaks of the Athenian empire as comprehending a thousand states. The language of the stage must not be taken too literally; but the number of the dependencies of Athens, at the time when the Peloponnesian confederacy attacked her, was undoubtedly very great. With a few trifling exceptions, all the islands of the AEgean, and all the Greek cities, which in that age fringed the coasts of Asia Minor, the Hellespont, and Thrace paid tribute to Athens, and implicitly obeyed her orders. The AEgean Sea was an Attic lake. Westward of Greece, her influence though strong, was not equally predominant. She had colonies and allies among the wealthy and populous Greek settlements in Sicily and South Italy, but she had no organized system of confederates in those regions; and her galleys brought her no tribute from the western seas. The extension of her empire over Sicily was the favourite project of her ambitious orators and generals. While her great statesman Pericles lived, his commanding genius kept his countrymen under control and forbade them to risk the fortunes of Athens in distant enterprises, while they had unsubdued and powerful enemies at their own doors. He taught Athens this maxim; but he also taught her to know and to use her own strength, and when Pericles had departed the bold spirit which he had fostered overleaped the salutary limits which he had prescribed. When her bitter enemies, the Corinthians, succeeded, in 431 B.C., in inducing Sparta to attack her, and a confederacy was formed of five-sixths of the continental Greeks, all animated by anxious jealousy and bitter hatred of Athens; when armies far superior in numbers and equipment to those which had marched against the Persians were poured into the Athenian territory, and laid it waste to the city walls; the general opinion was that Athens would, in two or three years at the farthest, be reduced to submit to the requisitions of her invaders. But her strong fortifications, by which she was girt and linked to her principal haven, gave her, in those ages, almost all the advantages of an insular position. Pericles had made her trust to her empire of the seas. Every Athenian in those days was a practised seaman. A state indeed whose members, of an age fit for service, at no time exceeded thirty thousand, and whose territorial extent did not equal half Sussex, could only have acquired such a naval dominion as Athens once held, by devoting, and zealously training, all its sons to service in its fleets. In order to man the numerous galleys which she sent out, she necessarily employed also large numbers of hired mariners and slaves at the oar; but the staple of her crews was Athenian, and all posts of command were held by native citizens. It was by reminding them of this, of their long practice in seamanship, and the certain superiority which their discipline gave them over the enemy's marine, that their great
