Caffi, born in Venice in 1778, was the descendant of a family of lawyers but had been a student of Mayr with regard to music. The well-off environment had allowed him to organize musical events and, after finishing his career as a magistrate, he devoted himself to musicology. His melodrama Il pegno di pace, with three voices and choirs, was given in 1810 in the grand hall of the Ridotto on the occasion of Napoleon's wedding with Maria Luisa of Austria. He died at the age of 96 in 1874. Girolamo Viezzoli was the closest friend of the Marches Nicola Vaccaj. The two had met in Venice in 1816 at the time of the opera Malvina, and the correspondence, begun in 1817, continued without interruption until the death of Vaccaj in Pesaro in 1848. Viezzoli was very active as a singer in Venetian home executions, in particular in The creation of the world and The four seasons of Haydn. In 1811 the first one took place at the Giovanni Battista Martini Conservatory in Bologna with Gioachino Rossini at the harpsichord. Viezzoli was certainly a well-known character not only in Venice: the Perugian composer Francesco Morlacchi, one of the main architects of the diffusion of Italian opera abroad and predecessor of Richard Wagner as Kapellmeister of the Saxon court theater, dedicated to him the song in 1822
