Fiorello Giraud created a roll in an opera that had how many acts?
Pagliacci Pagliacci (] ; literal translation, "Clowns") is an Italian opera in a prologue and two acts, with music and libretto by Ruggero Leoncavallo. It is the only Leoncavallo opera that is still widely performed. Opera companies have frequently staged "Pagliacci" with "Cavalleria rusticana" by Mascagni, a double bill known colloquially as 'Cav and Pag'.
Muzio Scevola Muzio Scevola ("Mucius Scaevola", HWV 13) is an opera seria in three acts about Gaius Mucius Scaevola. The Italian-language libretto was by Paolo Antonio Rolli, adapted from a text by Silvio Stampiglia. The music for the first act was composed by Filippo Amadei (family name sometimes given as Mattei), the second act by Giovanni Bononcini, and the third by George Frideric Handel. Collaborations of groups of composers were common in the 18th century, though this is the only one done in London. Bononcini had written the music for two earlier treatments of this story on his own, works dating from 1695 and 1710.
