Jone, ossia L’ultimo giorno di Pompei
Both Glauco and the high priest Arbace love Jone, while the slave Nidia loves Glauco. Arbace’s servant Burbo gives Nidia poison to pass to Glauco as a love potion. Arbace then tries to force Jone into the temple of Isis; Glauco rescues her but is condemned for sacrilege. Nidia exposes Arbace to the praetor, freeing Glauco. When Vesuvius erupts, Arbace dies; Jone and Glauco escape, while Nidia returns to the city.
