I have known one writer compile a history of the future, including the capture of Vologesus, the execution of Osroes (he is to be thrown to the lions), and, crowning all, our longdeferred triumph. In this prophetic vein, he sweeps hastily on to the end of his work; yet he finds time for the foundation in Mesopotamia of a city, greatest of the great, and fairest of the fair; he is still debating, however, whether the most appropriate name will be Victoria, Concord, or Peacetown; that is yet unsettled; we must leave the fair city unnamed for the present; but it is already thickly populated—with empty dreams and literary drivellings. He has also pledged himself to an account of coming events in India, and a circumnavigation of the Atlantic; nay, the pledge is half redeemed; the preface to the India is complete; the third legion, the Celtic contingent, and a small Moorish division, have crossed the Indus in full force under Cassius; our most original historian will soon be posting us up in their doings—their method of ‘receiving elephants,’ for instance—in letters dated Muziris or Oxydracae. These people’s uneducated antics are infinite; they have no eyes for the noteworthy, nor, if they had eyes, any adequate faculty of expression; invention and fiction provide their matter, and belief in the first word that comes their style; they pride themselves on the number of books they run to, and yet more on their titles; for these again are quite absurd: —So-and-so’s so many books of Parthian victories; The Parthis, book I ; The Parthis, book II —quite a rival to the Atthis , eh? Another does it (I have read the book) still more neatly—‘ The Parthonicy of Demetrius of Sagalassus .' I do not wish to ridicule or make a jest of these pretty histories; I write for a practical purpose: any one who avoids these and similar errors is already well on the road to historical success; nay, he is almost there, if the logical axiom is correct, that, with incompatibles, denial of the one amounts to affirmation of the other. Well, 1 may be told, you have now a clear field; the thorns and brambles have all been extirpated, the debris of others? buildings has been carted off, the rough places have been made smooth; come, do a little construction yourself, and show that you are not only good at destroying, but capable of yourself planning a model, in which criticism itself shall find nothing to criticize. Well then, my perfect historian must start with two indispensable qualifications; the one is political insight, the other the faculty of expression; the first is a gift of nature, which can never be learnt; the second should have been acquired by long practice, unremitting toil, and loving study of the classics. There is nothing technical here, and no room for any advice of mine; this essay does not profess to bestow insight and acumen on those who are not endowed with them by nature; valuable, or invaluable rather, would it have been, if it could recast and modify like that, transmute lead into gold, tin into silver, magnify a Conon or Leotrophides into Titormus or Milo. But what is the function of professional advice? not the creation of qualities which should be already there, but the indication of their proper use. No trainer, of course,—let him be Iccus, Herodicus, Theon, or who he may—will suggest that he can take a Perdiccas Omitting, with Dindorf, a note on Perdiccas which runs thus; ‘if Perdiccas it was, and not rather Seleucus’s son Antiochus, who was wasted to a shadow by his passion for his step-mother.’ and make an Olympic victor of him, fit to face Theagenes of Thasos or Polydamas of Scotussa; what he will tell you is that, given a constitution that will stand training, his system will considerably improve it. So with us—we are not to have every failure cast in our teeth, if we claim to have invented a system for so great and difficult a subject. We do not offer to take the first comer and make a historian of him—only to point out to any one who has natural insight and acquired literary skill certain straight roads (they may or may not be so in reality) which will bring him with less waste of time and effort to his goal.
