The foster-sister of Robert le Diable, and bride of Rambaldo, the Norman troubadour, She came to Palermo to place in the dukes hand her mothers will, which he was enjoined not to read till he was a virtuous man. When Bertram, his fiend-father, tempted his son to evil, Alice proved his good genius; and when, at last, Bertram claimed his soul as the price of his ill deeds, Alice read the will, and won him from the evil one.Meyerbeers Opera, Roberto il Diavolo.
