La lettera anonima
(The anonymous letter) is a farce in one act composed by Gaetano Donizetti in 1822 to a libretto by , a former monk and the official censor of the Kingdom of the Two Sicilies. Genoino based his libretto on his own farce which, in turn, had been based on  by Pierre Corneille in 1630. With a letter of recommendation from his teacher Johann Simon Mayr, Donizetti was in Naples and, on 12 May 1822, came to an agreement to write the opera with the impresario Domenico Barbaja, for whom he had already produced La zingara (The Gypsy Girl). Six weeks later he presented the new farce to the public, the premiere taking place on 29 June 1822. Overall, the opera appears to have been well received and given twenty performances, although according to Donizetti, "it was half-ruined by a novice singer (Cecconi)". However, as has been noted, "the score contains an attractive speciality number for the dancing master, Flageolet, and an extended quartet, '', the one number of the work to be praised by critics after the premiere" because it avoided "those caballetas and that symmetrical repetition of motifs which obliges all the performers to repeat the same musical phrases no matter what the different emotions may agitate them".
