Nabucco (Italian pronunciation: [naˈbukko]; short for Nabucodonosor [naˌbukoˈdɔːnozor]~[naˌbukodonoˈzɔr], English Nebuchadnezzar) is an Italian-language opera in four acts composed in 1841 by Giuseppe Verdi to an Italian libretto by Temistocle Solera. The libretto is based on biblical stories from the Book of Jeremiah and the Book of Daniel and the 1836 play by Auguste Anicet-Bourgeois and Francis Cornue, although Antonio Cortese's ballet adaptation of the play (with its necessary simplifications), given at La Scala in 1836, was a more important source for Solera than the play itself. Under its original name of Nabucodonosor, the opera was first performed at La Scala in Milan on 9 March 1842.
