I’m currently writing a chapter on the material representation of canons in early sixteenth-century northern Italian art. The number of canons in art  suggests that they played an important role in the musico-visual culture in courts and ecclesiastical institutions of this time. Some better known examples of canons in paintings include the Agnus Dei II of Josquin’s Missa L’homme armé super voces musicales in Dosso Dossi’s Allegory of Music and Ockeghem’s Prenez sur moy in one of the intarsia of Isabelle d’Este’s grotta at the Ducal Palace in Mantua.
