Are  Paul Bunyan and La sonnambula both Italian operas?
La sonnambula La sonnambula ("The Sleepwalker") is an opera semiseria in two acts, with music in the "bel canto" tradition by Vincenzo Bellini set to an Italian libretto by Felice Romani, based on a scenario for a "ballet-pantomime" written by Eugène Scribe and choreographed by Jean-Pierre Aumer called "La somnambule, ou L'arrivée d'un nouveau seigneur". The ballet had premiered in Paris in September 1827 at the height of a fashion for stage works incorporating somnambulism.
Teatro Regio Ducal The Teatro Regio Ducal (Italian, "Royal Ducal Theatre") was the opera house in Milan from 26 December 1717 until 25 February 1776, when it was burned down following a carnival gala. Many famous composers and their operas are associated with it, including the premieres of Mozart's "Ascanio in Alba", "Mitridate, re di Ponto", and "Lucio Silla". The opera house also saw the premiere of Maria Teresa Agnesi Pinottini's "Ciro in Armenia" in 1753; one of the earliest successfully received operas by a female composer. Variant forms such as "Regio-Ducal Teatro" and "Teatro Regio Ducale" are also seen.
