Were both Il pirata and Die Fledermaus by Vincenzo Bellini?
Il pirata Il pirata ("The Pirate") is an opera in two acts by Vincenzo Bellini to an Italian libretto by Felice Romani which was based on a three-act mélodrame from 1826, "Bertram, ou le Pirate" ("Bertram, or The Pirate") by Charles Nodier and "Raimonde" (actually Isidore Justin Séverin Taylor). However, this play was itself based upon a French translation of the "five-act verse tragedy" "Bertram, or The Castle of St Aldobrando" by Charles Maturin which appeared in London in 1816.
Luigi Pirandello Luigi Pirandello (] ; Girgenti,today known as Agrigento, 28 June 1867 – Rome 10 December 1936) was an Italian dramatist, novelist, poet and short story writer whose greatest contributions were his plays. He was awarded the 1934 Nobel Prize in Literature for "his almost magical power to turn psychological analysis into good theatre."
