Act 1 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.Leonora and Arturo retire as the country-folk return, strewing flowers in Enrico’s path. The King is delighted to lay down his arms and looks forward to returning to his love. Before he can depart, however, he is accosted by his elderly tutor, Clifford. It is an unwelcome and embarrassing encounter, since his mistress is Clifford’s own daughter, Rosmonda. 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. He has, however, heard rumours that the King has deserted Leonora and taken a mistress, and in his capacity as the King’s mentor he takes it upon himself to rebuke Enrico. He demands to see the unfortunate woman, whoever she may be, in order that he may try to lead her back to virtue. Enrico allows him to see her, though he urges him to be guided by compassion, and assures him that, once he knows her identity, he will be pleased to see her mount the throne of England.
