El profeta
Renowned for her wide vocal range and her dramatic roles on stage, Viardot gave performances that inspired composers such as Frédéric Chopin, Berlioz, Camille Saint-Saëns (who dedicated "Samson and Delilah" to her, and wanted her to sing the title role, but she declined on account of her age), and Giacomo Meyerbeer, for whom she created Fidès in "Le prophète".
