Answer
Missa Hercules Dux Ferrariae, a mass composed by Josquin, was dedicated to Ercole I d'Este, Duke of Ferrara. This work is a prime example of the polyphonic style that characterized the Renaissance period. It showcases Josquin's mastery of counterpoint and his ability to create complex and expressive musical textures. The mass is notable for its use of cantus firmus, a pre-existing melody that forms the foundation of the composition.
