Small panel paintings with religious subjects from the thirteenth and fourteenth centuries in Tuscany constituted a wide-ranging and popular category of objects for personal devotion and use. Comprising single panels, diptychs, triptychs and even polyptychs, they were just as popular as books of hours in northwest Europe. Just as with books of hours, the complete spectrum of art is covered, from modest panels produced on spec. To top-class works painted for demanding commissioners. This book is the first study of these objects as a category and aims to provide a systematic discussion of their most important aspects: typology and material quality, use and function, iconography, and their owners and commissioners.
