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.

Casanova tells us in his Memoirs that, during his later years at Dux, he
had only been able to 'hinder black melancholy from devouring his poor
existence, or sending him out of his mind,' by writing ten or twelve

Memoirs, and to the various books which he published during those years.
We see him jotting down everything that comes into his head, for his own
amusement, and certainly without any thought of publication; engaging in
learned controversies, writing treatises on abstruse mathematical
problems, composing comedies to be acted before Count Waldstein's
neighbours, practising verse-writing in two languages, indeed with more
