A short time ago, while making researches in the Royal Library for my History of Louis XIV, I stumbled by chance upon the Memoirs of M. d'Artagnan, printed-as were most of the works of that period, in which authors could not tell the truth without the risk of a residence, more or less long, in the Bastille-at Amsterdam, by Pierre Rouge. The title attracted me; I took them home with me, with the permission of the guardian, and devoured them. It is not my intention here to enter into an analysis of this curious work; and I shall satisfy myself with referring such of my readers as appreciate the pictures of the period to its pages. They will therein find portraits penciled by the hand of a master; and although these squibs may be, for the most part, traced upon the doors of barracks and the walls of cabarets, they will not find the likenesses of Louis XIII, Anne of Austria, Richelieu, Mazarin, and the courtiers of the period, less faithful than in the history of M. Anquetil. But, it is well known, what strikes the capricious mind of the poet is not always what affects the mass of readers. Now, while admiring, as others doubtless will admire, the details we have to relate, our main preoccupation concerned a matter to which no one before ourselves had given a thought.
