[1] 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.

[2] A concert performance was given at the Queen Elizabeth Hall, London with Yvonne Kenny in the title role, and later a recording followed.

[3] Scene 1 In the Woodstock Castle park, the country-folk acclaim Enrico (King Henry II) upon his return from his wars in Ireland.

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.

Clifford, for his part, is unaware of his daughter's predicament since he has been absent on a diplomatic mission in France, and believes that she is at home awaiting his return.

Her lover's absence has made Rosmonda miss Edegardo's company even more, but it has also given her time to appreciate the enormity of her conduct.

For a moment Clifford fails to recognize her, but then, the full situation dawning upon him, he bitterly reproaches her, and is only prevented from cursing her by her distress and evident remorse.

Enrico is distressed to see Rosmonda's plight, and all the more so since, as she recovers consciousness, she bids him to leave her and return to Leonora.

She feigns surprise, asking why she should find everyone so obviously embarrassed: the King looking angrily upon her, Clifford disturbed, and Rosmonda in tears.

As the councillors retire, she waylays Enrico and tries, first by reasoned argument, reminding him of the aid she gave him in gaining the throne, and then by seeking to reawaken his love, to win her way back into his heart.

To his surprise he finds that it is Clifford, who, imprisoned by Enrico but released by Leonora, has come to tell Rosmonda that she must leave England within the hour.

Scene 3 In a remote regions of the gardens of Woodstock, Rosmonda has agreed to meet Arturo so that they may set off together for Aquitaine.

Leonora appears to be almost convinced, but at this unlucky moment her followers return, informing her that an armed Enrico and his henchmen are approaching.

A distraught and anguished Leonora reproaches Enrico for forcing her to such an extreme: it is he, she insists, who is ultimately to blame, although both of them must be punished by Heaven's vengeance.
