The verdict of his contemporaries, ratified by posterity, has pronounced Demosthenes (380-322 B.C.) the greatest orator that has ever lived, yet he had no natural advantages for oratory. A feeble frame and a weak voice, a shy and awkward manner, the ungraceful gesticulations of one whose limbs had never been duly exercised, and a defective articulation, would have deterred most men from even attempting to address an Athenian assembly; but the ambition and perseverance of Demosthenes enabled him to triumph over every disadvantage. He improved his bodily powers by running, his voice by speaking aloud as he walked up hill, or declaimed against the roar of the sea; he practiced graceful delivery before a looking-glass, and controlled his unruly articulation by speaking with pebbles in his mouth. His want of fluency he remedied by diligent composition, and by copying and committing to memory the works of the best authors. By these means he came forth as the acknowledged leader of the assembly, and, even by the confession of his deadliest enemies, the first orator of Greece. His harangues to the people, and his speeches on public and private causes, which have been preserved, form a collection of sixty-one orations. The most important efforts of Demosthenes, however, were the series of public speeches referring to Philip of Macedon, and known as the twelve Philippics, a name which has become a general designation for spirited invectives. The main characteristic of his eloquence consisted in the use of the common language of his age and country. He took great pains in the choice and arrangement of his words, and aimed at the utmost conciseness, making epithets, even common adjectives, do the work of a whole sentence, and thus, by his perfect delivery and action, a sentence composed of ordinary terms sometimes smote with the weight of a sledge- hammer. In his orations there is not any long or close train of reasoning, still less any profound observations or remote and ingenious allusions, but a constant succession of remarks, bearing immediately on the matter in hand, perfectly plain, and as readily admitted as easily understood. These are intermingled with the most striking appeals either to feelings which all were conscious of, and deeply agitated by, though ashamed to own, or to sentiments which every man was panting to utter and delighted to hear thundered forth,--bursts of oratory, which either overwhelmed or relieved the audience. Such characteristics constituted the principal glory of the great orator.
