Are the sources of the most ancient Roman history, before ever an historical literature had arisen in Rome, worthy of credit? In former times a simple honest belief was prevalent concerning this point; it would have been considered as audacity and as a crime, if any one had doubted of the Roman history, especially that which Livy drew and set forth from the sources at his command. It is now quite incomprehensible to us to what a degree very ingenious men, like Scaliger, who had far more knowledge than we, received without any hesitation the details of ancient history, deeming, for instance, the lists of the kings of Sicyon to be quite as authentic as those of the kings of France. This state of literary innocence lasted as long as all education was purely philological, and derived from books only. In the seventeenth century, when in England, France, and Germany, a new era commenced for the civilization of mankind, many began to be startled at the contradictions which some individuals might have remarked before them, but had imposed on themselves silence upon the subject,--as for instance the Roman Valla, the discovery of whose grave is one of the most pleasing remembrances of my life, and Glareanus, who thereby irritated the ingenious Sigonius, a man, however, who had not the least idea of historical criticism. The Italians were for some time a-head of the rest of Europe, then the French followed, and shortly afterwards, the Germans. As early as towards the end of the sixteenth century lived Pighius, a native of the province of Cleves, who had original ideas with regard to historical criticism, but who has commenced much and finished nothing. Then followed Perizonius’ able criticism, and then the sceptical works of Bayle and Beaufort. It was not possible in the eighteenth century to receive the Roman history with the same credulity as in the sixteenth, since the sphere of the human mind had been so much enlarged during the seventeenth. People wanted to comprehend what had happened, and how it had come to pass, and so they could no more believe in the Roman history as they found it. O that Perizonius had gone on with the work which he had begun, and had formed the conviction that he must arrive at an historical result, without which belief no man can advance and succeed;--or, that others had proceeded in his track! But he was wanting in self-confidence, and others set themselves to the work with less comprehensive powers. Beaufort, a clever man, but whose studies had not been sufficiently comprehensive, forms at this time an epoch; but his literary and personal imperfections caused him to root up the tares with the wheat. Already before had Pouilly, in the ‘Mémoires de l’Académie des Inscriptions et des belles lettres,’ set forth the same opinions, but quite crudely. It was the time of that extreme scepticism which Bayle had given birth to, and Freret had confirmed. Beaufort did not feel the necessity of a good groundwork of
