"Son of a magistrate, Leoncavallo was a student of the composer Paolo Serrao (1830-1907) and Lauro Rossi (1810-1885) in San Pietro a Majella Conservatory, in his native Naples. Converted to the Wagnerian creed, he went to contemplate Wagner's Italian premiere of Rienzi, in Bologna, in 1876, planning to create an opera triptych with a Renaissance thematic which would be the peninsular equivalent of the tetralogy Ring Cycle: the three parts of Crepusculum would be I Medici (the only one finished), Gerolamo Savonarola and Cesare Borgia. At that time, he composed his first opera, Chatterton, which, however, it would be staged only two decades later, in 1896." (Perpetuo)
