Question: Which opera was produced first, Nabucco or Il prigioniero?

Context paragraphs:
Nell Gwynne (operetta): Nell Gwynne is a three-act comic opera composed by Robert Planquette, with a libretto by H. B. Farnie.  The libretto is based on the play "Rochester" by William Thomas Moncrieff.  The piece was a rare instance of an opera by a French composer being produced first in London.  Farnie had written an earlier libretto on the same subject, with the same name, for composer Alfred Cellier, which was produced at the Prince's Theatre in Manchester in 1876.

Cinque variazioni (Berio): Cinque variazioni ("Five variations") is a composition for solo piano by Luciano Berio, written in 1952/3 and greatly revised in 1966.  It was published by Suvini Zerboni and the first performance was given by Berio in Milan in 1953.  The variations are based on a three-note melodic cell—""fratello""[014]—from the opera "Il prigioniero" by Luigi Dallapiccola, to whom the work is dedicated .  Major changes between the two versions are indicated below, but many other small changes may be found, mostly additions to render the harmony more complex.

Va, pensiero: "Va, pensiero " (] ), also known in English as the "Chorus of the Hebrew Slaves", is a chorus from the third act of the opera "Nabucco" (1842) by Giuseppe Verdi, with a libretto by Temistocle Solera, inspired by Psalm 137.  It recollects the period of Babylonian captivity after the loss of the First Temple in Jerusalem in c. 500 BCE.  The opera with its powerful chorus established Verdi as a major composer in 19th-century Italy.  The full incipit is "Va, pensiero, sull'ali dorate", meaning "Go, thought, on golden wings".

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.

Maggio Musicale Fiorentino: Maggio Musicale Fiorentino is an annual arts festival in Florence, including a notable opera festival; it was founded in April 1933 by conductor Vittorio Gui with the aim of presenting contemporary and forgotten operas in visually dramatic productions.  It was the first music festival in Italy.  The first opera presented was Verdi's early "Nabucco", his early operas then being rarely staged.  It now takes place between late April, May and into June, typically with four operas.

Aleksandr Antonenko: Aleksandrs Antoņenko (born in Riga June 26, 1975) is a Latvian tenor who specializes in dramatic repertoire.  He debuted on stage as "Prince" in "Rusalka" in 2009.  Since then, he has performed in cities such as Baden-Baden, Berlin, Monte Carlo, and Stockholm.  Notable appearances include a 2012 appearance in Tosca, as Cavaradossi, at La Scala.  In the same year he was seen as Otello at the Royal Opera House in London.  In 2013 he appeared in the role of "Radames" in "Aida" at the Zurich Opera House.  He followed that performance by appearing as Manrico in Il Trovatore at the Berlin State Opera.  He has also performed in "Turandot" as Calaf at La Scala.  In 2013, he appeared in the role of "Ismaele" in Giuseppe Verdi's opera "Nabucco", conducted by Nicola Luisotti at the Teatro alla Scala, Milan as well as the Splendid Palace in Latvia.  In 2014 he announced that he will perform at The Orchestra Hall in "Cavalleria rusticana" and "Pagliacci".  He will also appear as the title role in the Metropolitan Opera's new production of "Otello", which will open the Met's 2015-2016 season.  The production is notable within American opera circles due to the Met's decision to abandon their tradition of blackface for the role of Otello.  Other future performances include "Norma" at the Bavarian State Opera, "Otello" at Barcelona's Gran Teatre del Liceu and Zürich's Opernhaus, and "Pagliacci" at the Royal Opera House in London.

Ulisse: Ulisse is an opera in a prologue and two acts composed by Luigi Dallapiccola to his own libretto based on the legend of Ulysses.  It premiered at the Deutsche Oper in Berlin (in German translation by Karl-Heinrich Kreith as "Odysseus") on 29 September 1968 conducted by Lorin Maazel with Erik Saedén in the title role.  "Ulisse" was Dallapiccola's last opera and took eight years to compose.  As in his previous operas, "Volo di notte" and "Il prigioniero", his declared theme was "the struggle of man against some force much stronger than he".

Il prigioniero: Il prigioniero ("The Prisoner") is an opera (originally a radio opera) in a prologue and one act, with music and libretto by Luigi Dallapiccola.  The opera was first broadcast by the Italian radio station RAI on 1 December 1949.  The work is based on the short story "La torture par l'espérance" ("Torture by Hope") from the collection "Nouveaux contes cruels" by the French writer Auguste Villiers de l'Isle-Adam and from "La Légende d'Ulenspiegel et de Lamme Goedzak" by Charles de Coster.  Some of the musical material is based on Dallapiccola's earlier choral work on a similar theme, "Canti di prigionia" (1938).  Dallapiccola composed "Il prigioniero" in the period of 1944–1948.  The work contains seven parts and lasts about 50 minutes.  The musical idiom is serialism, and it is one of the first completed operas using that compositional method.
