All the din of war Was hushed to rest. Within a city's walls, Beneath a marble portico, were seen Statesmen and orators, in robes of peace, Holding discourse. The assembled multitude Sat in the crowded theatre, and bent To hear the voice of gorgeous Tragedy Breathing, in solemn verse, or ode sublime, Her noble precepts. The broad city's gates Poured forth a mingled throng--impatient steeds Champing their bits, and neighing for the course: Merchants slow driving to the busy port Their ponderous wains: Religion's holy priests Leading her red-robed votaries to the steps Of some vast temple: young and old, with hands Crossed on their breasts, hastening to walks and shades Suburban, where some moralist explained The laws of mind and virtue. On a rock A varied group appeared: some dragged along The rough-hewn block; some shaped it into form; Some reared the column, or with chisel traced Forms more than human; while Content sat near, And cheered with songs the toil of Industry. But, as the poet adds, Soon passed this peaceful pageant: War again Brandished his bloody lance-- and then began that dismal period between the "Age of Pericles" and the interference of the Romans--embracing the three Peloponnesian wars, the rising power of Macedonia under Philip of Macedon, the wars of Alexander and the contentions that followed--known as the period of the civil convulsions of Greece. CHAPTER XI. THE PELOPONNESIAN WARS, AND THE FALL OF ATHENS. CAUSES OF THE FIRST WAR. The various successful schemes of Pericles for enriching and extending the power of Athens were regarded with fear and jealousy by Sparta and her allies, who were only waiting for a reasonable excuse to renew hostilities. The opportunity came in 435 B.C. Corinth, the ally of Sparta, had become involved in a war with Corcy'ra, one of her colonies, when the latter applied to Athens for assistance. Pericles persuaded the Athenians to grant the assistance, and a small fleet was dispatched to Corcyra. The engagement that ensued, in which the Athenian ships bore a part --the greatest contest, Thucydides observes, that had taken place between Greeks to that day--was favorable to the Corinthians; but the sight of a larger Athenian squadron advancing toward the scene of action caused the Corinthians to retreat. This first breach of the truce was soon followed by another. Potidæ'a, a Corinthian colony, but tributary to Athens, revolted, on account of some unjust demands that the Athenians had enforced against it, and claimed and obtained the assistance of the Corinthians. Thus, in two instances, were Athens and Corinth, though nominally at peace, brought into conflict as open enemies. THE CONGRESS AT SPARTA.--THE PERSECUTION OF PERICLES.
