Question: Are I Lombardi alla prima crociata and Giasone both operas?

full_context: Document 1: Tosca: Tosca (] ) is an opera in three acts by Giacomo Puccini to an Italian libretto by Luigi Illica and Giuseppe Giacosa. It premiered at the Teatro Costanzi in Rome on 14 January 1900. The work, based on Victorien Sardou's 1887 French-language dramatic play, "La Tosca", is a melodramatic piece set in Rome in June 1800, with the Kingdom of Naples's control of Rome threatened by Napoleon's invasion of Italy. It contains depictions of torture, murder and suicide, as well as some of Puccini's best-known lyrical arias.
Document 2: I Lombardi alla prima crociata: I Lombardi alla Prima Crociata ("The Lombards on the First Crusade") is an operatic "dramma lirico" in four acts by Giuseppe Verdi to an Italian libretto by Temistocle Solera, based on an epic poem by Tommaso Grossi, which was "very much a child of its age; a grand historical novel with a patriotic slant". Its first performance was given at the Teatro alla Scala in Milan on 11 February 1843. Verdi dedicated the score to Maria Luigia, the Habsburg Duchess of Parma, who died a few weeks after the premiere.
Document 3: Il Bellerofonte: Il Bellerofonte is an 18th-century Italian opera in three acts by the Czech composer Josef Mysliveček. It conforms to the serious type (opera seria) that was typically set in the distant past. The libretto, based on the Greek legend of Bellerophon, was written by Giuseppe Bonecchi. The work was dedicated to King Ferdinand I of the Two Sicilies and was first performed at the Teatro San Carlo in Naples on 20 January 1767, the birthday of his father, King Charles III of Spain. The cast featured two stellar singers of the time, Caterina Gabrielli and Anton Raaff, in the leading roles. The opera was only the composer's second one, and the first that permitted him the opportunity to write music for first-rate vocal artists. The production was highly successful, indeed responsible for a meteoric rise in his reputation as an operatic composer. From the time of the premiere of "Bellerofonte" until his death in 1781, Mysliveček succeeded in having more new "opere serie" brought into production than any other composer in Europe. During the same time span, he also had more new operas staged at the Teatro San Carlo in Naples than any other composer.
Document 4: Griselda (A. Scarlatti): Griselda is an opera seria in three acts by the Italian composer Alessandro Scarlatti, the last of Scarlatti’s operas to survive completely today. The libretto is by Apostolo Zeno, with revisions by an anonymous author. Zeno wrote his work in 1701 and it had already been set by Pollarolo and Antonio Maria Bononcini (Albinoni, Giovanni Bononcini and Vivaldi would later produce versions). It is based on the story of Patient Griselda from Boccaccio's "Decameron". Scarlatti's opera was first performed at the Teatro Capranica, Rome in January, 1721 with an all-male cast (five castratos and a tenor).
Document 5: Casanova's Homecoming: Casanova's Homecoming is an opera in three acts by Dominick Argento to an English libretto by the composer, based in part on Giacomo Casanova's memoirs. It was first performed by the Minnesota Opera in Saint Paul, Minnesota in 1985.
Document 6: Carlo Guasco: Carlo Guasco (16 March 1813 – 13 December 1876) was a celebrated Italian operatic tenor who sang in Italian and other European opera houses from 1837 to 1853. Although he sang in many world premieres, he is most remembered today for having created the leading tenor roles in Verdi's "I Lombardi alla prima crociata", "Ernani", and "Attila".
Document 7: Griselda (Vivaldi): Griselda (] ) is a dramma per musica in three acts that was composed by Antonio Vivaldi. The opera uses a revised version of the 1701 Italian libretto by Apostolo Zeno that was based on Giovanni Boccaccio's "The Decameron" (X, 10, "The Patient Griselda"). The celebrated Venetian playwright Carlo Goldoni was hired to adapt the libretto for Vivaldi. The opera was first performed in Venice at the Teatro San Samuele on 18 May 1735.
Document 8: Aroldo: Aroldo (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on and adapted from their earlier 1850 collaboration, "Stiffelio". The first performance was given in the Teatro Nuovo Comunale in Rimini on 16 August 1857.
Document 9: 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.
Document 10: 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.
Document 11: Jérusalem: Jérusalem is a grand opera in four acts by Giuseppe Verdi. The libretto was to be an adaptation and partial translation of the composer's original 1843 Italian opera, "I Lombardi alla prima crociata". It was the one opera which he regarded as the most suitable for being translated into French and, taking Eugène Scribe's advice, Verdi agreed that a French libretto was to be prepared by Alphonse Royer and Gustave Vaëz, who had written the libretto for Donizetti's most successful French opera, "La favorite". The opera received its premiere performance at the Salle Le Peletier in Paris on 26 November 1847. The maiden production was designed by Paul Lormier (costumes), Charles Séchan, Jules Diéterle and Édouard Desplechin (sets of Act I, Act II, scene 1, Act III scene 1, and Act IV), and Charles-Antoine Cambon and Joseph Thierry (sets for Act II, scene 2 and Act III, scene 2).
Document 12: La traviata discography: The following is a partial discography of the many audio and video recordings of Giuseppe Verdi's opera, La traviata. Based on the novel "La dame aux Camélias" by Alexandre Dumas, fils, "La traviata" has been a staple of the operatic repertoire since its premiere on 6 March 1853 at the Teatro La Fenice in Venice.
Document 13: List of operas set in the Crusades: Operas set against the background of the medieval Crusades can be found in the earliest examples of the art form and continue to be written into the 21st century. Many of the works listed here contain characters and plots based on real or legendary figures of the time such as Tancred, Prince of Galilee, Godfrey of Bouillon or Jaufre Rudel. The majority are set, at least in part, in the Holy Land and the surrounding region and deal with the conflicts between the Christians and Muslims. Others, such as Donizetti's "Gabriella di Vergy", deal with the misadventures of knights returning from the Crusades. In the case of "Gabriella di Vergy", Raoul de Coucy returns from the Third Crusade to find that his beloved Gabriella has married Lord Fayel. Following a duel, Fayel cuts out the heart of the unfortunate Raoul and presents it in an urn to Gabriella. The only comedy in the list, Rossini's "Le comte Ory", recounts the attempts by Ory and his friends to seduce the Countess of Formoutiers and the women of her household while their men are away at the Crusades. Ory's ploy of dressing up as nuns to gain access to the women is foiled when the Crusaders return. Many of the libretti for the operas listed are based either directly or indirectly on Torquato Tasso's epic poem, "La Gerusalemme liberata" ("Jerusalem Delivered"), or on Voltaire's tragic play, "Zaïre".
Document 14: Giulio Sabino: The opera, staged in six or seven European countries at the end of the 18th century, was the subject of a parody in Antonio Salieri's 1786 work "Prima la musica e poi le parole".
Document 15: Dafne: Dafne is the earliest known work that, by modern standards, could be considered an opera. The libretto by Ottavio Rinuccini survives complete; the mostly-lost music was completed by Jacopo Peri, but at least two of the six surviving fragments are by Jacopo Corsi. "Dafne" was first performed during Carnival of 1598 (1597 old style) at the Palazzo Corsi.
