Like Count Waldstein, however, the Prince de Ligne made the widest allowances, understanding the chafing of Casanova’s restless spirit.  “Casanova has a mind without an equal, from which each word is extraordinary and each thought a book.”

On the 16th December, he wrote Casanova:  “One is never old with your heart, your genius and your stomach.”

Casanova’s own comment on his trip away from Dux will be found in the Memoirs.  “Two years ago, I set out for Hamburg, but my good genius made me return to Dux.  What had I to do at Hamburg?”

On the 10th December, Casanova’s brother Giovanni [Jean] died.  He was the Director of the Academy of Painting at Dresden.  Apparently the two brothers could not remain friends.

Giovanni left two daughters, Teresa and Augusta, and two sons, Carlo and Lorenzo.  While he was unable to remain friendly with his brother, Casanova apparently wished to be of assistance to his nieces, who were not in the best of circumstances, and he exchanged a number of letters with Teresa after her father’s death.

On the occasion of Teresa Casanova’s visit to Vienna in 1792, Princess Clari, oldest sister of the Prince de Ligne, wrote of her:  “She is charming in every way, pretty as love, always amiable; she has had great success.  Prince Kaunitz loves her to the point of madness.”

In a letter of the 25th April 1796, Teresa assured her “very amiable and very dear uncle” that the cautions, which occupied three-fourths of his letter, were unnecessary; and compared him with his brother Francois, to the injury of the latter.  On the 5th May, Teresa wrote: 

“Before thanking you for your charming letter, my very kind uncle, I should announce the issue of our pension of one hundred and sixty crowns a year, which is to say, eighty crowns apiece; I am well satisfied for I did not hope to receive so much.”  In the same letter, Teresa spoke of seeing much of a “charming man,” Don Antonio, who was no other than the rascally adventurer Don Antonio della Croce with whom Casanova had been acquainted since 1753, who assisted Casanova in losing a thousand sequins at Milan in 1763; who in 1767, at Spa, following financial reverses, abandoned his pregnant mistress to the charge of Casanova; and who in August 1795, wrote to Casanova:  “Your letter gave me great pleasure as the sweet souvenir of our old friendship, unique and faithful over a period of fifty years.”

It is probable that, at this time, Casanova visited Dresden and Berlin also.  In his letter “To Leonard Snetlage,” he writes:  “’That which proves that revolution should arrive,’ a profound thinker said to me in Berlin, last year, ‘is that it has arrived.’”

On the 1st March, 1798, Carlo Angiolini, the son of Maria Maddalena, Casanova’s sister, wrote to Casanova:  “This evening, Teresa will marry M. le Chambellan de Veisnicht [Von Wessenig] whom you know well.”  This desirable marriage received the approval of Francesco also.  Teresa, as the Baroness Wessenig, occupied a prominent social position at Dresden.  She died in 1842.
