After visiting Rome, Milan, and Vienna, for which last city he wrote "Linda di Chamouni," our composer returned to Paris, and in 1843 wrote "Don Pasquale" for the Théâtre Italien, and "Don Sebastian" for the Académie. Its lugubrious drama was fatal to the latter, but the brilliant gaiety of "Don Pasquale," rendered specially delightful by such a cast as Grisi, Mario, Tamburini, and Lablache, made it one of the great art attractions of Paris, and a Fortunatus purse for the manager. The music of this work, perhaps, is the best ever written by Donizetti, though it lacks the freshness and sentiment of his "Elisir d'Amore," which is steeped in rustic poetry and tenderness like a rose wet with dew. The production of "Maria di Rohan" in Vienna the same year, an opera with some powerful dramatic effects and bold music, gave Ronconi the opportunity to prove himself not merely a fine buffo singer, but a noble tragic actor. In this work Donizetti displays that rugged earnestness and vigour so characteristic of Verdi; and, had his life been greatly prolonged, we might have seen him ripen into a passion and power at odds with the elegant frivolity which for the most part tainted his musical quality. Donizetti's last opera, "Catarina Comaro," the sixty-third one represented, was brought out at Naples in the year 1844, without adding aught to his reputation. Of this composer's long list of works only ten or eleven retain any hold on the stage, his best serious operas being "La Favorita," "Linda," "Anna Bolena," "Lucrezia Borgia," and "Lucia;" the finest comic works, "L'Elisir d'Amore," "La Fille du Regiment," and "Don Pasquale." In composing Donizetti never used the pianoforte, writing with great rapidity and never making corrections. Yet curious to say, he could not do anything without a small ivory scraper by his side, though never using it. It was given him by his father when commencing his career, with the injunction that, as he was determined to become a musician, he should make up his mind to write as little rubbish as possible, advice which Donizetti sometimes forgot.
