Don John of Austria is a ballad opera in three acts by Isaac Nathan to a libretto by Jacob Levi Montefiore.
[1] Quote from the opera's title page: It premiered on 3 May 1847 at the Royal Victoria Theatre, Sydney and enjoyed a successful run of six performances.
[3] It has been produced only twice since: two performances (12 and 14 September 1997) at Spitalfields, London, by Spitalfields Market Opera with The Chelsea Opera Group directed by Philip Parr and conducted by Alexander Briger,[4] and semi-staged performances on 18 and 20 October 2007 – in two acts – at the City Recital Hall, Angel Place, Sydney, also conducted by Briger.
[1] Nathan’s fast-paced opera tells of the rivalry in love of Philip II of Spain and his illegitimate half-brother Don John of Austria.
The libretto follows Delavigne's 1835 Don Juan d'Autriche fairly closely, except for the addition of a scene near the end with Agnes alone, where she sings "They tell us that a home of light there is, where praying seraphs glow".
