Mario Tiberini

Mario Tiberini (8 September 1826 – 16 October 1880) was an Italian tenor who sang leading roles in the opera houses of Europe and the Americas in a career spanning 25 years.

He also gave solo concerts in New York and Boston launched by the opera impresario Bernard Ullman who billed Tiberini as a descendant of the Roman Emperor Tiberius.

There he met and fell in love with the soprano Angiolina Ortolani who was singing the title role in Linda di Chamounix.

[3][4] An inscription on a lithograph in the Biblioteca Trivulziana [it] in Milan states that he died believing he was Manrico, the protagonist of Il trovatore.

However, according to Denise Gallo writing in The Cambridge Verdi Encyclopedia, there is no mention of this delusion in the records of the asylum, and it may well be a theatrical legend.
