The Ninth Day of Giovanni Boccaccio’s Decameron is significant both for numerological and structural reasons. The volume incorporates a multitude of disciplinary perspectives including literary studies, visual arts, political history, and gender studies. Taking a holistic approach, the contributors to the volume trace the dense and multi-layered web of interrelations between the narrative units and the rest of the Decameron. Connections between individual stories are highlighted and interactions between Day Nine and its counterparts in the book are analysed. In doing so, The Decameron Ninth Day in Perspective synthesizes existing scholarship but also opens up new horizons for future work.
