Even in the age of Plutarch there were discerning men who rejected the popular account of the foundation of Rome, because that account appeared to them to have the air, not of a history, but of a romance or a drama. Plutarch, who was displeased at their incredulity, had nothing better to say in reply to their arguments than that chance sometimes turns poet, and produces trains of events not to be distinguished from the most elaborate plots which are constructed by art. But though the existence of a poetical element in the early history of the Great City was detected so many ages ago, the first critic who distinctly saw from what source that poetical element had been derived was James Perizonius, one of the most acute and learned antiquaries of the seventeenth century. His theory, which in his own days attracted little or no notice, was revived in the present generation by Niebuhr, a man who would have been the first writer of his time, if his talent for communicating truths had borne any proportion to his talent for investigating them. That theory has been adopted by several eminent scholars of our own country, particularly by the Bishop of St. David's, by Professor Malde, and by the lamented Arnold. It appears to be now generally received by men conversant with classical antiquity; and indeed it rests on such strong proofs, both internal and external, that it will not be easily subverted. A popular exposition of this theory, and of the evidence by which it is supported, may not be without interest even for readers who are unacquainted with the ancient languages. The Latin literature which has come down to us is of later date than the commencement of the Second Punic War, and consists almost exclusively of works fashioned on Greek models. The Latin metres, heroic, elegiac, lyric, and dramatic, are of Greek origin. The best Latin epic poetry is the feeble echo of the Iliad and Odyssey. The best Latin eclogues are imitations of Theocritus. The plan of the most finished didactic poem in the Latin tongue was taken from Hesiod. The Latin tragedies are bad copies of the masterpieces of Sophocles and Euripides. The Latin philosophy was borrowed, without alteration, from the Portico and the Academy; and the great Latin orators constantly proposed to themselves as patterns the speeches of Demosthenes and Lysias.
