The public events of this period are summed up in the struggle for supremacy between Athens and Sparta. The race which had shown itself capable of united action against the common foe now develops within itself two antagonistic and mutually exclusive principles. The age of the despots is past. The flowering-time of the colonies is over. The stone of Tantalus in Persia has been removed from Hellas. But it remains for Sparta and Athens to fight out the duel of Dorian against Ionian prejudices, of oligarchy against democracy. Both states have received their definite stamp, or permanent #êthos#--Sparta from semi-mythical Lycurgus; Athens from Solon, Cleisthenes, and Pericles. Their war is the warfare of the powers of the sea with the powers of the land, of Conservatives with Liberals, of the rigid principle of established order with the expansive spirit of intellectual and artistic freedom. What is called the Peloponnesian war--that internecine struggle of the Greeks--is the historical outcome of this deep-seated antagonism. And the greatest historical narrative in the world--that of Thucydides--is its record. To dwell upon the events of this war would be superfluous. Athens uniformly exhibits herself as a dazzling, brilliant, impatient power, led astray by the desire of novelty, and the intoxicating sense of force in freedom. Sparta proceeds slowly, coldly, cautiously; secures her steps; acts on the defensive; spends no strength in vain; is timid, tentative, and economical of energy; but at the decisive moment she steps in and crushes her antagonist. Deluded by the wandering fire of the inspiration of Alcibiades, the Athenians venture to abandon the policy of Pericles and to contemplate the conquest of Syracuse. A dream of gigantic empire, in harmony with their expansive spirit, but inconsistent with the very conditions of vitality in a Greek state, floated before their imaginations. In attempting to execute it, they overreached themselves and fell a prey to Sparta. With the fall of Athens faded the real beauty and grandeur of Greece. Athens had incarnated that ideal of loveliness and sublimity. During her days of prosperity she had expressed it in superb works of art and literature, and in the splendid life of a free people governed solely by their own intelligence. Sparta was strong to destroy this life, to extinguish this light of culture. But to do more she had no strength. Stiffened in her narrow rules of discipline, she was utterly unable to sustain the spiritual vitality of Hellas, or to carry its still vigorous energy into new spheres. It remained for aliens to accomplish this.
