Are both pieces The Immortal Hour and L'incoronazione di Poppea an opera?
L'incoronazione di Poppea L'incoronazione di Poppea (SV 308, "The Coronation of Poppaea") is an Italian opera by Claudio Monteverdi, with a libretto by Giovanni Francesco Busenello, first performed at the Teatro Santi Giovanni e Paolo in Venice during the 1643 carnival season. One of the first operas to use historical events and people, it describes how Poppaea, mistress of the Roman emperor Nero, is able to achieve her ambition and be crowned empress. The opera was revived in Naples in 1651, but was then neglected until the rediscovery of the score in 1888, after which it became the subject of scholarly attention in the late 19th and early 20th centuries. Since the 1960s, the opera has been performed and recorded many times.
L'arbre enchanté L’arbre enchanté, ou Le tuteur dupé ("The Magic Tree, or, the Tutor Duped"), Wq 42, is a one-act opéra comique by Christoph Willibald Gluck to a libretto based on the 1752 opéra-comique "Le poirier" ("The Peartree") with a text by Jean-Joseph Vadé. Vadé's libretto was based on a tale from Boccaccio's "Decameron", as retold by Jean de La Fontaine. Gluck's opera was written for the nameday of Emperor Francis Stephan, premiering at the Schönbrunn palace in Vienna on the evening of October 3, 1759, anniversary of the death of Saint Francis of Assisi.
