Jone, ossia L'ultimo giorno di Pompei is an opera in four acts by Errico Petrella.
The Italian-language libretto was by Giovanni Peruzzini, after Edward Bulwer-Lytton's famous novel The Last Days of Pompeii.
Most of these singers were quite well known at the time, especially Carlo Negrini who was one of Italy's leading tenors and had created the role of Gabriele Adorno in Verdi's Simon Boccanegra a year earlier.
Both Glauco, a noble Roman, and Arbace, the high priest of Isis, love Jone.
Arbace offers to save Glauco's life in return for Jone's favors, which she refuses.
