And not only are the Memoirs a literary curiosity; they are almost equally curious from a bibliographical point of view. The manuscript was written in French and came into the possession of the publisher Brockhaus, of Leipzig, who had it translated into German, and printed. From this German edition, M. Aubert de Vitry re-translated the work into French, but omitted about a fourth of the matter, and this mutilated and worthless version is frequently purchased by unwary bibliophiles. In the year 1826, however, Brockhaus, in order presumably to protect his property, printed the entire text of the original MS. in French, for the first time, and in this complete form, containing a large number of anecdotes and incidents not to be found in the spurious version, the work was not acceptable to the authorities, and was consequently rigorously suppressed. Only a few copies sent out for presentation or for review are known to have escaped, and from one of these rare copies the present translation has been made and solely for private circulation. In conclusion, both translator and 'editeur' have done their utmost to present the English Casanova in a dress worthy of the wonderful and witty original. AUTHOR'S PREFACE I will begin with this confession: whatever I have done in the course of my life, whether it be good or evil, has been done freely; I am a free agent. The doctrine of the Stoics or of any other sect as to the force of Destiny is a bubble engendered by the imagination of man, and is near akin to Atheism. I not only believe in one God, but my faith as a Christian is also grafted upon that tree of philosophy which has never spoiled anything. I believe in the existence of an immaterial God, the Author and Master of all beings and all things, and I feel that I never had any doubt of His existence, from the fact that I have always relied upon His providence, prayed to Him in my distress, and that He has always granted my prayers. Despair brings death, but prayer does away with despair; and when a man has prayed he feels himself supported by new confidence and endowed with power to act. As to the means employed by the Sovereign Master of human beings to avert impending dangers from those who beseech His assistance, I confess that the knowledge of them is above the intelligence of man, who can but wonder and adore. Our ignorance becomes our only resource, and happy, truly happy; are those who cherish their ignorance! Therefore must we pray to God, and believe that He has granted the favour we have been praying for, even when in appearance it seems the reverse. As to the position which our body ought to assume when we address ourselves to the Creator, a line of Petrarch settles it: 'Con le ginocchia della mente inchine.'
