Paris In October 1838, Donizetti moved to Paris vowing never to have dealings with the San Carlo again after the King of Naples banned the production of Poliuto on the grounds that such a sacred subject was inappropriate for the stage. In Paris, he offered Poliuto to the Opéra and it was set to a new and expanded four-act French-language libretto by Eugène Scribe with the title, Les Martyrs. Performed in April 1840, it was his first grand opera in the French tradition and was quite successful. Before leaving that city in June 1840, he had time to oversee the translation of Lucia di Lammermoor into Lucie de Lammermoor as well as to write La fille du régiment, his first opera written specifically to a French libretto. This became another success. 1840–1843: Back and forth between Paris, Milan, Vienna, and Naples After leaving Paris in June 1840, Donizetti was to write ten new operas, although not all were performed in his lifetime. Before arriving in Milan by August 1840, he visited Switzerland and then his hometown of Bergamo, eventually reaching Milan where he was to prepare an Italian version of La fille du régiment. No sooner was that accomplished than he was back in Paris to adapt the never-performed 1839 libretto L'Ange de Nisida as the French-language La favorite, the premiere of which took place on 2 December 1840. Then he rushed back to Milan for Christmas, but returned almost immediately and by late February 1841 was preparing a new opera, Rita, ou Deux hommes et une femme. However, it was not staged until 1860. Donizetti returned once more to Milan where he stayed with the accommodating Giuseppina Appiano Stringeli with whom he had a pleasant time. Unwilling to leave Milan, but encouraged to return to Paris by Michele Accursi (with whom the composer was to be involved in Paris in 1843), he oversaw the December production of Maria Padilla at La Scala, and began writing Linda di Chamounix in preparation for March 1842 travels to Vienna, in which city he had been engaged by the royal court. During this time and prior to leaving for Vienna, he was persuaded to conduct the premiere of Rossini's Stabat Mater in Bologna in March 1842. Friends—including his brother-in-law, Antonio Vasselli (known as Totò)—continually attempted to persuade him to take up an academic position in Bologna rather than the Vienna court engagement, if
