Arrigo_Boito

Arrigo Boito (Italian: [arˈriːɡo ˈbɔito]; born Enrico Giuseppe Giovanni Boito; 24 February 1842 – 10 June 1918) was an Italian librettist, composer, poet and critic whose only completed opera was Mefistofele. Among the operas for which he wrote the libretti are Giuseppe Verdi's monumental last two operas Otello and Falstaff as well as Amilcare Ponchielli's La Gioconda.
Along with Emilio Praga and his brother Camillo Boito, he is regarded as one of the prominent representatives of the Scapigliatura (Italian bohemian) artistic movement. He wrote essays under the anagrammatic pseudonym of Tobia Gorrio
