After a chance meeting with Merelli close to La Scala, the impresario gave him a copy of Temistocle Solera's libretto which had been rejected by the composer Otto Nicolai. Verdi describes how he took it home, and threw "it on the table with an almost violent gesture. ... In falling, it had opened of itself; without my realising it, my eyes clung to the open page and to one special line: 'Va, pensiero, sull'ali dorate'." While it has been noted that "Verdi read it enthusiastically" (and certainly he states that, while he attempted to sleep, he was kept awake and read and re-read the libretto three times), others have stated that he read the libretto very reluctantly or, as recounted by Lessona, that he "threw the libretto in a corner without looking at it anymore, and for the next five months he carried on with his reading of bad novels ... [when] towards the end of May he found himself with that blessed play in his hands: he read the last scene over again, the one with the death of Abigaille (which was later cut), seated himself almost mechanically at the piano ... and set the scene to music." Nevertheless, Verdi still refused to compose the music, taking the manuscript back to the impresario the next day. But Merelli would not accept the refusal; he immediately stuffed the papers back into Verdi's pocket and according to the composer, "not only threw me out of his office, but slammed the door in my face and locked himself in".

At the very least, both Verdi's and Lessona's versions end with a complete score. Performance history 19th century The opening performances, limited to only eight because the season was coming to an end, were "a colossal success." But, when the new season opened on 13 August 1842, around 60 performances had been added by the end of that year. Numerous Italian and foreign theatres put on this opera in the years immediately following, including La Fenice in Venice in December 1842. In 1843 Donizetti conducted it in Vienna, and other stagings took place that year in Lisbon and Cagliari. But the definitive name of
