Are I Lombardi alla prima crociata and Giasone both operas?
Giasone Giasone ("Jason") is an opera in three acts and a prologue with music by Francesco Cavalli and a libretto by Giacinto Andrea Cicognini. It was premiered at the Teatro San Cassiano, Venice on 5 January 1649, during carnival. "Giasone" was "the single most popular opera of the 17th century". The plot is loosely based on the story of Jason and the golden fleece, but the opera contains many comic elements too.
Nabucco Nabucco (] ; short for Nabucodonosor ] ~] , 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 books of Jeremiah and 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.
