This book uses Pseudo-Dionysius and his mystic theology to explore attitudes and beliefs about images in the early medieval West and Byzantium. Composed in the early sixth century, the Corpus Dionysiacum, the collection of texts transmitted under the name of Dionysius the Areopagite, developed a number of themes which have a predominantly visual and spatial dimension.

The contributors embrace religious studies, philosophy, theology, art, and architectural history, to consider the depth of the interaction between the Corpus Dionysiacum
