Nabucco (short for Nabucodonosor, English Nebuchadnezzar) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Temistocle Solera, based on the biblical story and the play by Anicet-Bourgeois and Francis Cornu. Its first performance took place on March 9, 1842 at the Teatro alla Scala, Milan under the original name. The definitive name for the opera and the protagonist were attributed at a performance at the San Giacomo Theatre of Corfu, in September, 1844. The best-known number from this opera is Hebrews' Chorus, Va, pensiero, sull'ali dorate - 'Fly, thought, on golden wings'.
