On December 26, 1815, the first day of the carnival season, Rossini produced his opera, "Torvaldo e Dorliska," at the Teatro Argentina, in Rome, and at the same time signed a contract with Cesarini, the impresario of the theatre, to have the first act of a second opera ready on the twentieth day of the following January. For this opera Rossini was to receive 400 Roman scudi (the equivalent of about $400) after the first three performances, which he was to conduct seated at the pianoforte in the orchestra, as was then the custom. He seems to have agreed to take any libretto submitted by the impresario and approved by the public censor; but there are indications that Sterbini, who was to write the libretto, had already suggested a remodelling of Paisiello's "Barber." In order to expedite the work of composition it was provided in the contract that Rossini was to take lodgings with a singer named Zamboni, to whom the honor fell of being the original of the town factotum in Rossini's opera. Some say that Rossini completed the score in thirteen days; some in fifteen. Castil-Blaze says it was a month, but the truth is that the work consumed less than half that period. Donizetti, asked if he believed that Rossini had really written the score in thirteen days, is reported to have replied, no doubt with a malicious twinkle in his eyes: "It is very possible; he is so lazy." Paisiello was still alive, and so was at least the memory of his opera, so Rossini, as a precautionary measure, thought it wise to spike, if possible, the guns of an apprehended opposition. So he addressed a letter to the venerable composer, asking leave to make use of the subject. He got permission and then wrote a preface to his libretto (or had Serbini write it for him), in which, while flattering his predecessor, he nevertheless contrived to indicate that he considered the opera of that venerable musician old-fashioned, undramatic, and outdated. "Beaumarchais's comedy, entitled 'The Barber of Seville, or the Useless Precaution,'" he wrote, "is presented at Rome in the form of a comic drama under the title of 'Almaviva, ossia l'inutile Precauzione,' in order that the public may be fully convinced of the sentiments of respect and veneration by which the author of the music of this drama is animated with regard to the celebrated Paisiello, who has already treated the subject under its primitive title. Himself invited to undertake this difficult task, the maestro Gioachino Rossini, in order to avoid the reproach of entering rashly into rivalry with the immortal author who preceded him, expressly required that 'The Barber of Seville' should be entirely versified anew, and also that new situations should be added for the musical pieces which, moreover, are required by the modern theatrical taste, entirely changed since the time when the renowned Paisiello wrote his work."
