"God what charms!" Giacomo Casanova is said to have exclaimed during his journey through Switzerland in the summer of 1760. The 35-year-old seducer of women had just decided to enter the Einsiedeln monastery as a monk when he spotted a beauty outside his window and instantly changed his mind. Madame de***, a married lady from Solothurn, was the reason that Casanova's journey took him to the little town, but of course she did not remain the only chosen one on his triumphal procession between Zurich and Geneva. The libretto of the comic opera "Casanova in Switzerland" by Paul Burkhard and Richard Schweizer pretty much follows Giacomo Casanova's tales of love, hate, disappointment and intrigue. The Swiss composer Paul Burkhard, today best known for his musical "Feuerwerk", "Die kleine Niederdorfoper" and "D'Zäller Wiehnacht", had written the work together with his librettist Richard Schweizer for the Zurich Opera House, where the successful premiere took place in 1943.
