This book centers on the copy of the Homilies of Gregory of Nazianzus produced in Constantinople around 880 for the emperor Basil I as a gift from the patriarch Photios. The manuscript includes forty-six full page miniatures, most of which do not directly illustrate the text they accompany, but instead provide a visual commentary. Vision and Meaning in Ninth-Century Byzantium deals with how such communication worked, and examines the types of messages that pictures could convey in ninth-century Byzantium.
