You and I hold, I think, the same opinion, after having made, each in his own way, close researches as to the grand and splendid figure of Catherine de’ Medici. Consequently, I have thought that my historical studies upon that queen might properly be dedicated to an author who has written so much on the history of the Reformation; while at the same time I offer to the character and fidelity of a monarchical writer a public homage which may, perhaps, be valuable on account of its rarity. [*] The name of the man who tried this experiment at Barcelona should be given as Salomon de Caux, not Caus. That great man has always been unfortunate; even after his death his name is mangled. Salomon, whose portrait taken at the age of forty-six was discovered by the author of the “Comedy of Human Life” at Heidelberg, was born at Caux in Normandy. He was the author of a book entitled “The Causes of Moving Forces,” in which he gave the theory of the expansion and condensation of steam. He died in 1635. CATHERINE DE’ MEDICI INTRODUCTION There is a general cry of paradox when scholars, struck by some historical error, attempt to correct it; but, for whoever studies modern history to its depths, it is plain that historians are privileged liars, who lend their pen to popular beliefs precisely as the newspapers of the day, or most of them, express the opinions of their readers. Historical independence has shown itself much less among lay writers than among those of the Church. It is from the Benedictines, one of the glories of France, that the purest light has come to us in the matter of history,--so long, of course, as the interests of the order were not involved. About the middle of the eighteenth century great and learned controversialists, struck by the necessity of correcting popular errors endorsed by historians, made and published to the world very remarkable works. Thus Monsieur de Launoy, nicknamed the “Expeller of Saints,” made cruel war upon the saints surreptitiously smuggled into the Church. Thus the emulators of the Benedictines, the members (too little recognized) of the Academie des Inscriptions et Belles-lettres, began on many obscure historical points a series of monographs, which are admirable for patience, erudition, and logical consistency. Thus Voltaire, for a mistaken purpose and with ill-judged passion, frequently cast the light of his mind on historical prejudices. Diderot undertook in this direction a book (much too long) on the era of imperial Rome. If it had not been for the French Revolution, _criticism_ applied to history might then have prepared the elements of a good and true history of France, the proofs for which had long been gathered by the Benedictines. Louis XVI., a just mind, himself translated the English work in which Walpole endeavored to explain Richard III.,--a work much talked of in the last century.
