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

Related documents: [0]  [DOC] 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. [END] 
[1]  [DOC] 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. [END]
