Rosmonda d'Inghilterra (Rosamund of England) is a melodramma or opera in two acts by Gaetano Donizetti. The Italian libretto was written by Felice Romani originally for Coccia's Rosmunda (1829). It is based on the legend of Rosamund Clifford (The Fair Rosamund).
It premiered at the Teatro della Pergola, Florence on 27 February 1834 and was revived only in Livorno in 1845. A request for it to be approved for the Teatro di San Carlo in Naples was submitted in June 1837 and it was revised as Eleonora di Gujenna for that theatre, but there is no evidence that it was actually performed there.
It was largely forgotten until its English rediscovery in 1975 by Patric Schmid, co-founder of Opera Rara, who recognised Donizetti's handwriting by chance on the manuscript in the library of the Naples Conservatory. A concert performance was given at the Queen Elizabeth Hall, London with Yvonne Kenny in the title role, and later a recording followed.
Scene 1
In the Woodstock Castle park, the country-folk acclaim Enrico (King Henry II) upon his return from his wars in Ireland. As they greet him, Leonora (Queen Eleanor) appears, followed by the King’s page, Arturo. It is revealed that Arturo was once taken under Leonora’s protection as a young orphan, and consequently feels deeply indebted to her. As a result of these feelings, he has told her a powerful secret: that Enrico has a mistress, and that upon his departure for Ireland he lodged her in a tower at Woodstock and left Arturo to watch over her. Her identity is so secretive that even Arturo does not know her name. Leonora realizes that the page has fallen in love with this mysterious woman. Leonora encourages him by suggesting that she will help him win her for himself, but at the same time she clearly seeks revenge upon her rival.
