In addition, Bellini was introduced to the librettist Felice Romani, who proposed the subject of the composer’s first project, "Il pirata", to which the young man willingly agreed, especially after he realised that the story "provided several passionate and dramatic situations.. ..that such Romantic characters were then an innovation on the operatic stage." From that time forward, there began a strong professional relationship with Romani; he became Bellini’s primary creative partner, providing the librettos for six of Bellini’s operas which followed, the result being that "no other Italian opera composer of the time showed such an attachment to a single librettist". Although Romani was known to treat composers poorly, he evidently had great respect for Bellini, even acceding to his requests for revisions. For his part, Bellini admired "the sonorous and elegance of the poet's verses"
