This aggression of the Thebans silenced the opponents of Pericles, who now saw that the war had actually begun, and that active preparations should be made. Athens immediately sent messengers to her allies, tributary as well as free, and contributions flowed in from all parts of the Athenian empire. Athens had soon three hundred triremes fit for service, twelve hundred horsemen, sixteen hundred bowmen, and twenty-nine thousand hoplites. The Acropolis was filled with the treasure which had long been accumulating, not less than six thousand talents—about $7,000,000 of our money—an immense sum at that time, when gold and silver were worth twenty or thirty times as much as at present. Moreover, the various temples were rich in votive offerings, in deposits, plate, and sacred vessels, while the great statue of the goddess, lately set up in the Parthenon by Phidias, composed of gold and ivory, was itself valued at four hundred talents. The contributions of allies swelled the resources of Athens to one thousand talents, or over $11,000,000. (M493) Sparta, on the other hand, had but few ships, no funds, and no powers of combination, and it would seem that success would be on the side of Athens, with her unrivaled maritime skill, and the unanimity of the citizens. Pericles did not promise successful engagements on the land, but a successful resistance, and the maintenance of the empire. His policy was purely defensive. But if Sparta was weak in money and ships, she was rich in allies. The entire strength of the Peloponnesus was brought out, assisted by Megarians, Bœotians, Phocians, Locrians, and other States. Corinth, Megara, Sicyon, Elis, and other maritime cities furnished ships while Bœotians, Phocians, and Locrians furnished cavalry. Not even to resist the Persian hosts was so large a land force collected, as was now assembled to destroy the supremacy of Athens. And this great force was animated with savage hopes, while the Athenians were not without desponding anticipations, for there was little hope of resisting the Spartans and their allies on the field. The Spartans, moreover, resolved, by means of their allies, to send a fleet able to cope with that of Athens, and even were so transported with enmity and jealousy as to lay schemes for invoking the aid of Persia.
