Una follia

Una follia is a farsa in one act by composer Gaetano Donizetti. The work premiered on 15 December 1818 at the Teatro San Luca in Venice. The opera uses the same Italian-language libretto by Bartolomeo Merelli after August von Kotzebue's Der Graf von Burgund that Donizetti used for his Enrico di Borgogna a month earlier, but with different music. It was given one performance and "never performed again, and its score has never been found."
