 Adjustments to the story in order to create the libretto

Bellini and his librettist Romani took tremendous liberties with this already unusual story and devised a plot where the King, in order to resolve the problem of his double marriage, sends Agnes to live at a cottage on Lake Montolino.Philip then sends her brother to secretly watch over her, while masquerading under the name Valdeburgo.Agnes has assumed the name of Alaide and hides under a veil.
