Thus in oratory, as in history, the ancients can boast of most illustrious examples, never even equaled. Still, we cannot tell the comparative merits of the great classical orators of antiquity, with the more distinguished of our times. Only Mirabeau, Pitt, Fox, Burke, Brougham, Webster, and Clay, can even be compared with them. In power of moving the people, some of our modern reformers and agitators may be mentioned favorably; but their harangues are comparatively tame when read. [Sidenote: Varro.] In philosophy, the Greeks and Romans distinguished themselves more than even in poetry, or history, or eloquence. Their speculations pertained to the loftiest subjects which ever tasked the intellect of man. But this great department deserves a separate chapter. There were respectable writers, too, in various other departments of literature, but no very great names whose writings have descended to us. Contemporaries had an exalted opinion of Varro, who was considered the most learned of the Romans, as well as their most voluminous author. He was born ten years before Cicero, and he is highly commended by Augustine. [Footnote: Born B.C. 116; _Civ. Dei_., vi. 2.] He was entirely devoted to literature, took no interest in passing events, and lived to a good old age. St. Augustine says of him, "that he wrote so much that one wonders how he had time to read; and that he read so much, we are astonished how he found time to write." He composed four hundred and ninety books. Of these only one has descended to us entire--"De Re Rustica"--written at the age of eighty; but it is the best treatise which has come down from antiquity on ancient agriculture. We have parts of his other books, and we know of books which have entirely perished which, for their information, would be invaluable; especially his "Divine Antiquities," in sixteen books--his great work, from which St. Augustine drew his materials for his "City of God." He wrote treatises on language, on the poets, on philosophy, on geography, and various other subjects. He wrote satire and criticism. But although his writings were learned, his style was so bad that the ages have failed to preserve him. It is singular that the truly immortal books are most valued for their artistic excellences. No man, however great his genius, can afford to be dull. Style is to written composition, what delivery is to a public speaker. John Foster, one of the finest intellects of the last generation, preached to a "handful" of hearers, while "Satan" Montgomery drew ecstatic crowds. Nobody goes to hear the man of thoughts, every body to hear the man of words, being repelled or attracted by _manner_. [Sidenote: Seneca.]
