Question: Are I Lombardi alla prima crociata and Giasone both operas?
Context: Gennaro Lombardi was an Italian immigrant who moved to the United States in 1897, and known for opening the first pizzeria in the United States, Lombardi's.  He opened a small grocery store in New York City's Little Italy.  An employee of his, Antonio Totonno Pero, also an Italian immigrant, began making pizza for the store to sell.  Their pizza became so popular that Lombardi opened the first US pizzeria in 1905, naming it simply Lombardi's. 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. Wet-on-wet, or alla prima (Italian, meaning "at first attempt"), is a painting technique, used mostly in oil painting, in which layers of wet paint are applied to previously administered layers of wet paint.  This technique requires a fast way of working, because the work has to be finished before the first layers have dried.  It may also be referred to as direct painting or the French term au premier coup (at first stroke). Lance Richlin (born 1961) is a classical realist painter and a sculptor based in Torrance, California.  His oil painting technique is an alla prima technique that requires the paint not to dry until completion. 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). 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.

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".
