6. ORATORY, RHETORIC, AND HISTORY.--We may distinguish three epochs in the history of Attic prose from Pericles to Alexander the Great: first, that of Pericles and Thucydides; second, that of Lysias, Socrates, and Plato; and, third, that of Demosthenes and Aeschines. Public speaking had been common in Greece from the earliest times, but as the works of Athenian orators alone have come down to us, we may conclude that oratory was cultivated in a much higher degree at Athens than elsewhere. No speech of Pericles has been preserved in writing; only a few of his emphatic and nervous expressions were kept in remembrance; but a general impression of the grandeur of his oratory long prevailed among the Greeks, from which we may form a clear conception of his style. The sole object of the oratory of Pericles was to produce conviction; he did not aim to excite any sudden or transient burst of passion by working on the emotions of the heart; nor did he use any of those means employed by the orators of a later age to set in motion the unruly impulses of the multitude. His manner was tranquil, with hardly any change of feature; his garments were undisturbed by any oratorical gesticulations, and his voice was equable and sustained. He never condescended to flatter the people, and his dignity never stooped to merriment. Although there was more of reasoning than imagination in his speeches, he gave a vivid and impressive coloring to his language by the use of striking metaphors and comparisons, as when, at the funeral of a number of young persons who had fallen in battle, he used the beautiful figure, that "the year had lost its spring."
