But perhaps the most suggestive example of all is furnished by the brief world history of Justin, which, if not quite entire, has been preserved as to its main structure in various manuscripts. This work is an artistic epitome of a large, and in its day authoritative, history of the world, written by Trogus Pompeius. Justin, when a student in Rome in the day of the early Cæsars, was led to make an epitome of this work, seemingly as proof to his friends in the provinces that he was not wasting his time. He did his task so well that future generations saw no reason to trouble themselves with the prolixities of the original work, but were content to copy and re-copy the epitome, pointing the moral that brevity, next to artistic excellence, is the surest road to permanent remembrance for the historian,--a lesson which many modern writers have overlooked to their disadvantage. CHAPTER III THE METHODS OF THE HISTORIANS It is a curious fact, a seeming paradox, that the first two great histories ever written--the histories, namely, of Herodotus and Thucydides--should stand out pre-eminently as types of two utterly different methods of historical writing. Herodotus, “the Father of History,” wrote with the obvious intention to entertain. There is no great logicality of sequence in his use of materials; he simply rambles on from one subject to another with little regard for chronology, but with the obvious intention everywhere to tell all the good stories that he has learned in the course of his journeyings. It would be going much too far to say that there is no method in his collocation of materials, but what method he has is quite generally overshadowed and obscured in the course of presentation. Thus, for example, he is writing the history of the Persian wars, and he has reached that time in the history of Persia when Cambyses comes to the throne and prepares to invade Egypt. The mention of Egypt gives him, as it were, the cue for an utterly new discourse, which he elaborates to the extent of an entire book, detailing all that he has learned of Egypt itself, its history, its people, and their manners and customs, without, for the most part, referring in any way whatever to Cambyses. He returns to the Persian king ultimately, to be sure, and takes up his story regardless of the digression, and seemingly quite oblivious of any incongruity in the fact of having introduced very much more extraneous matter in reference to Egypt than the entire subject matter proper of the Persian Empire. The method of Herodotus was justified by the results. There is every reason to believe that he was enormously popular in his own time,--as popularity went in those days,--and he has held that popularity throughout all succeeding generations. But it has been said of him often enough that this work is hardly a history in the narrower sense of the word; it is a pleasing collection of tales, in which no
