So unfortunately prevalent was this view that a writer was not called a historian unless he had considerable pretensions to style. Thus, men who could write, and had written, in an informal way, excellent historical accounts, were not studied by their countrymen as historians. Their writings were relegated to the limbo of antiquarian remains. The habit of writing notes of their campaigns, memoranda of their public conduct, copies of their speeches, &c. had for some time been usual among the abler or more ambitious nobles. Often these were kept by them, laid by for future elaboration: oftener still they were published, or sent in the form of letters to the author's friends. The letters of Cicero and his numerous correspondents present such a series of raw material for history; and in reading any of the antiquarian writers of Rome we are struck by the large number of monographs, essays, pamphlets, rough notes, commentaries, and the like, attributed to public men, to which they had access. It is quite clear that for many years these documents had existed, and equally clear that, unless their author was celebrated or their style elegant, the majority of readers entirely neglected them. Nevertheless they formed a rich material for the diligent and capable historian. In using them, however, we could not expect him to show the same critical acumen, the same impartiality, as a modern writer trained in scientific criticism and the broad culture of international ideas; to expect this would be to expect an impossibility. To look at events from a national instead of a party point of view was hard; to look at them from a human point of view, as Polybius had done, was still harder. Thus we cannot expect from Republican Rome any historical work of the same scope and depth as those of Herodotus and Thucydides; neither the dramatic genius of the one nor the philosophic insight of the other was to be gained there. All we can look for is a clear comprehensive narrative, without flagrant misrepresentation, of some of the leading episodes, and such we fortunately possess in the memoirs of Caesar and the biographical essays of Sallust. The immediate object of the Commentaries of JULIUS CAESAR (100-44 B.C.), was no doubt to furnish the senate with an authentic military report on the Gallic and Civil Wars. But they had also an ulterior purpose. They aspired to justify their author in the eyes of Rome and of posterity in his attitude of hostility to the constitution.
