With these views, I many years ago deliberately selected this subject, for a novel, which has advanced by slow steps to such a degree of completeness as it has now attained. Having determined on trying my success in classical fiction, the conspiracy of Cataline appeared to me, a theme particularly well adapted for the purpose, as being an actual event of vast importance, and in many respects unparalleled in history; as being partially familiar to every one, thoroughly understood perhaps by no one, so slender are the authentic documents concerning it which have come down to us, and so dark and mysterious the motives of the actors. It possessed, therefore, among other qualifications, as the ground-work of a historical Romance, one almost indispensable—that of indistinctness, which gives scope to the exercise of imagination, without the necessity of falsifying either the truths or the probabilities of history. Of the execution, I have, of course, nothing to say; but that I have sedulously avoided being overlearned; that few Latin words will be found in the work—none whatsoever in the conversational parts, and none but the names of articles which have no direct English appellation; and that it is sufficiently simple and direct for the most unclassical reader. I hope that the costume, the manners of the people, and the antiquarian details will be found sufficiently correct; if they be not, it is not for want of pains or care; for I have diligently consulted all the authorities to which I could command access. To the history of the strange events related in this tale, I have adhered most scrupulously; and I believe that the dates, facts, and characters of the individuals introduced, will not be found in any material respect, erroneous or untrue; and here I may perhaps venture to observe, that, on reading the most recently published lectures of Niebuhr, which never fell in my way until very lately, I had the great satisfaction of finding the view I have always taken of the character and motives of Cataline and his confederates, confirmed by the opinion of that profound and sagacious critic and historian. I will only add, that it is hardly probable that "the Roman Traitor" would ever have been finished had it not been for the strenuous advice of a friend, in whose opinion I have the utmost confidence, Mr. Benjamin, to whom some of the early chapters were casually shown, two or three years ago, and who almost insisted on my completing it. It is most fitting, therefore, that it should be, as it is, introduced to the world under his auspices; since but for his favourable judgment, and for a feeling on my own part that to fail in such an attempt would be scarce a failure, while success would be success indeed, it would probably have never seen the light of day!
