"[3] Later, retiring to Viareggio to found a school of music, Pacini took time to assess the state of opera in Italy and, during a five-year period during which he stopped composing, laid out his ideas in his Memoirs.
[3] Certainly, Pacini recognized Rossini's strengths and his dominance during this period: "Everyone followed the same school, the same fashions, and as a result they were all imitators of the great luminary ....
If I was a follower of the great man from Pesaro, so was everyone else"[4] After Rossini moved to Paris in 1824, Pacini and his contemporaries (Giacomo Meyerbeer, Nicola Vaccai, Michele Carafa, Carlo Coccia, Vincenzo Bellini, Gaetano Donizetti, the brothers Federico and Luigi Ricci, and Saverio Mercadante) collectively began to change the nature of Italian opera and took bel canto singing in a new direction.
[citation needed] This change in attitude can be credited to the revival of two key works: Vaccai's Giulietta e Romeo and Pacini's L'ultimo giorno di Pompei, both composed in 1825 within a few weeks of each other.
Arabi nelle Gallie (Milan, 1827) reached many of the world's most important stages and was the first Pacini opera to be given in the United States.
It was staged frequently in Italy, and it was not until 1830 that Bellini's first success, Il pirata (also Milan, 1827) passed Gli arabi nelle Gallie in number of performances at the Teatro alla Scala.
Donizetti had departed for Paris, Bellini had died, and Mercadante's major successes were behind him, thus Verdi offered the only important competition.
Pacini's successes during this time period include La fidanzata corsa (Naples, 1842), Maria, regina d'Inghilterra (Palermo, 1843), Medea (Palermo, 1843 with several later revisions, the last of which was in Naples in 1853), Lorenzino de' Medici (Venice, 1845), Bondelmonte (Florence, 1845), Stella di Napoli (Naples,1845) and La regina di Cipro (Turin, 1846).
This period of accomplishments was followed by a long but slow decline, marked only by the moderate successes of La punizione (Venice, 1854), Il saltimbanco (Rome, 1858), and Niccolò de' Lapi (Florence, 1873).
