Rossini wrote his first opera, Demetrio e Polibio in 1806 not even fifteen. His official debut was in Venice in 1810 with the opera La Cambiale di Matrimonio. In the following two decades Rossini composed 39 operas, 4 or 5 new ones per year, with some controversial premieres, such as the Barber of Seville legendary fiasco in Rome in 1816 and some extraordinary successes: La Gazza Ladra, Zelmira and Semiramide, the last opera premiered in Italy in 1823.
La Sonnambula was a complete triumph, since its premiere. The newspapers wrote of “a melody that goes to the heart, an instrumentation always beautiful and well built” and reported of “endless applauses”. The story revolves around the character of Amina, the archetypal of the slandered innocent.
In the church Madonna del Pilar with its magnificent Baroque interiors and fine stuccoes on the 16th March 1822, by special concession as it was Lent, was celebrated the marriage between Gioachino Rossini and Ysabel Colbran crowning the great love and successful artistic alliance between the most prominent opera composer of the time and his muse.
