Дон Паскуале
Jonson's comedy had been used before as the basis for an opera: in 1800 Antonio Salieri's "Angiolina ossia Il Matrimonio", and in 1810 Stefano Pavesi wrote the opera "Ser Marcantonio" which in turn formed the basis for Donizetti's Don Pasquale with characters based upon the Commedia dell'arte (thus Morose becomes Don Pasquale who is based on Pantelone). Later still, in 1930 there was Mark Lothar's "Lord Spleen" (in German).
