Elvira

This is a ballad telling us an unusual, mystical story.
The prince and the king are both in love with Elvira, who is a forester's daughter.
To get rid of his rival, the king sends his son to Morgana's castle, where Morgana should bring prince to destruction.
In the meantime, the king forces Elvira to marry him. She denies his 'offer.'
The king gets furious and orders to burn her in flames.
But all is not lost for Elvira: the power of her love helps her defeat the death and, in turn, save the prince from dying...
