Don John of Austria (opera)

Don John of Austria is a ballad opera in three acts by Isaac Nathan to a libretto by Jacob Levi Montefiore. It is the first opera to be written, composed and produced in Australia.

Quote from the opera's title page:

The plot is taken and many scenes are literal translations from Casimir Delavigne's celebrated comedy of "Don John of Austria" (Don Juan d'Autriche).
