There cannot, moreover, exist the slightest doubt that the wantonness with which Richelieu, in furtherance of his own private interests, poured out so freely on the scaffold some of the proudest blood of France, did much towards destroying that prestige which had hitherto environed the high nobility. When Biron perished upon the block, although his death was decreed by the sovereign, and that sovereign, moreover, was their own idolized Henri IV, the people marvelled and even murmured; but in after-years they learned through the teaching of the Cardinal that nobles were merely men; while the exile of the persecuted Marie de Medicis, and the privations to which she was exposed through his agency, taught them that even royalty itself was not invulnerable to the malice or vengeance of its opponents; and unhappily for those by whom Richelieu was succeeded in power, the lesson brought forth its fruits in due season. Thus much premised, I shall confine myself to a brief explanation of the manner in which I have endeavoured to perform my self-imposed task. For one wilful, but as I trust excusable, inaccuracy, I throw myself on the indulgence of my critics. Finding my pages already overloaded with names, and that they must consequently induce a considerable strain upon the memory of such readers as might not chance to be intimately acquainted with the domestic history of the period under consideration, I have, from the commencement of the work, designated the Duc de Sully by the title which he ultimately attained, and by which he is universally known, rather than confuse the mind of my readers by allusions to M. de Béthune, M. de Rosny, and finally M. de Sully, when each and all merely signified the same individual; and I feel persuaded that this arrangement will be generally regarded as a judicious one, inasmuch as it tends to lessen a difficulty already sufficiently great; a fact which will be at once apparent on reference to the biographical table at the head of each volume. On the other hand I have, contrary to my previous system, but in justice to myself, carefully, and even perhaps somewhat elaborately, multiplied the footnotes, in order to give with precision the several authorities whence I deduced my facts; and I must be excused should this caution appear uselessly tedious or pedantic to the general reader, as I am anxious on this occasion to escape the accusation which was once brought against me when it was equally undeserved, of having "quoted at secondhand," and even drawn my materials from "historical romances of the time." It is, of course, easy to make assertions of this nature at random; but when a writer feels that he or she has conscientiously performed a duty voluntarily undertaken, it is painful to be misjudged; especially when, as in the present instance, nearly three years have been devoted to the work.
