But, however this may be, I was fortunate enough to find the set of letters which I was most anxious to find the letters from Henriette, whose loss every writer on Casanova has lamented. Henriette, it will be remembered, makes her first appearance at Cesena, in the year 1748; after their meeting at Geneva, she reappears, romantically 'a propos', twenty-two years later, at Aix in Provence; and she writes to Casanova proposing 'un commerce epistolaire', asking him what he has done since his escape from prison, and promising to do her best to tell him all that has happened to her during the long interval. After quoting her letter, he adds: 'I replied to her, accepting the correspondence that she offered me, and telling her briefly all my vicissitudes. She related to me in turn, in some forty letters, all the history of her life. If she dies before me, I shall add these letters to these Memoirs; but to-day she is still alive, and always happy, though now old.' It has never been known what became of these letters, and why they were not added to the Memoirs. I have found a great quantity of them, some signed with her married name in full, 'Henriette de Schnetzmann,' and I am inclined to think that she survived Casanova, for one of the letters is dated Bayreuth, 1798, the year of Casanova's death. They are remarkably charming, written with a mixture of piquancy and distinction; and I will quote the characteristic beginning and end of the last letter I was able to find. It begins: 'No, it is impossible to be sulky with you!' and ends: 'If I become vicious, it is you, my Mentor, who make me so, and I cast my sins upon you. Even if I were damned I should still be your most devoted friend, Henriette de Schnetzmann.' Casanova was twenty-three when he met Henriette; now, herself an old woman, she writes to him when he is seventy-three, as if the fifty years that had passed were blotted out in the faithful affection of her memory. How many more discreet and less changing lovers have had the quality of constancy in change, to which this life-long correspondence bears witness? Does it not suggest a view of Casanova not quite the view of all the world? To me it shows the real man, who perhaps of all others best understood what Shelley meant when he said:
True love in this differs from gold or clay That to divide is not to take away.
But, though the letters from women naturally interested me the most, they were only a certain proportion of the great mass of correspondence which I turned over. There were letters from Carlo Angiolini, who was afterwards to bring the manuscript of the Memoirs to Brockhaus; from Balbi, the monk with whom Casanova escaped from the Piombi; from the Marquis Albergati, playwright, actor, and eccentric, of whom there is some account in the Memoirs; from the Marquis Mosca, 'a distinguished man of letters whom I was anxious to see,' Casanova tells us in the same volume in which he describes his visit to the Moscas at Pesaro; from Zulian, brother of the Duchess of Fiano; from Richard Lorrain, 'bel homme, ayant de l'esprit, le ton et le gout de la bonne societe', who came to settle at Gorizia in 1773, while Casanova was there; from the Procurator Morosini, whom he speaks of in the Memoirs as his 'protector,' and as one of those through whom he obtained permission to return to Venice. His other 'protector,' the 'avogador' Zaguri, had, says Casanova, 'since the affair of the Marquis Albergati, carried on a most interesting correspondence with me'; and in fact I found a bundle of no less than a hundred and thirty-eight letters from him, dating from 1784 to 1798. Another bundle contains one hundred and seventy-two letters from Count Lamberg. In the Memoirs Casanova says, referring to his visit to Augsburg at the end of 1761:
I used to spend my evenings in a very agreeable manner at the house of Count Max de Lamberg, who resided at the court of the Prince-Bishop with the title of Grand Marshal. What particularly attached me to Count Lamberg was his literary talent. A first-rate scholar, learned to a degree, he has published several much esteemed works. I carried on an exchange of letters with him which ended only with his death four years ago in 1792.
Casanova tells us that, at his second visit to Augsburg in the early part of 1767, he 'supped with Count Lamberg two or three times a week,' during the four months he was there. It is with this year that the letters I have found begin: they end with the year of his death, 1792. In his 'Memorial d'un Mondain' Lamberg refers to Casanova as 'a man known in literature, a man of profound knowledge.' In the first edition of 1774, he laments that 'a man such as M. de S. Galt' should not yet have been taken back into favour by the Venetian government, and in the second edition, 1775, rejoices over Casanova's return to Venice. Then there are letters from Da Ponte, who tells the story of Casanova's curious relations with Mme. d'Urfe, in his 'Memorie scritte da esso', 1829; from Pittoni, Bono, and others mentioned in different parts of the Memoirs, and from some dozen others who are not mentioned in them. The only letters in the whole collection that have been published are those from the Prince de Ligne and from Count Koenig.
