Maximos the Confessor (580–662) occupies a unique position in the history of Byzantine philosophy, theology, and spirituality. His profound spiritual experiences and penetrating theological vision found complex and often astonishing expression in his unparalleled command of Greek philosophy, making him one of the most challenging and original Christian thinkers of all time. So thoroughly did his thought come to influence the Byzantine theological tradition that it is impossible to trace the subsequent history of Orthodox Christianity without knowledge of his work.

The Ambigua (or “Book of Difficulties”) is Maximos’s greatest philosophical and doctrinal work, in which his daring originality, prodigious talent for speculative thinking, and analytical acumen are on lavish display. In the Ambigua, a broad range of theological topics—cosmology, anthropology, the philosophy of mind and language, allegory, asceticism, and metaphysics—are transformed in a synthesis of Aristotelian logic, Platonic metaphysics, Stoic psychology, and the arithmetical philosophy of a revived Pythagoreanism. The result is a labyrinthine map of the mind’s journey to God that figured prominently in the Neoplatonic revival of the Komnenian Renaissance and the Hesychast Controversies of the Late Byzantine period.

This remarkable work has never before been available in a critically-based edition or English translation.

From the veils of the first-century Jewish temple, to the Orthodox iconostasis, to the tramezzi of Renaissance Italy, screens of various shapes, sizes, and materials have been used to separate spaces and order communities in religious buildings. Drawn from papers presented at a recent Dumbarton Oaks Byzantine Studies symposium, the contributors to this volume use a variety of perspectives to approach the history of religious screens and examine the thresholds that they mark. Focusing on the Middle Ages and Renaissance in the East and West, the volume includes discussions of screens in Egypt, Byzantium, the Gothic West and Italy. Some authors argue that screens, and particularly the one marking the threshold between the sanctuary/choir and nave, were conduits rather than barriers. Other authors emphasize the critical role of screens in dividing the laity and clergy, men and women, the pure and impure.

This volume provides new research on the history of religious screen and important insights into the many ways in which the sacred and profane are separated within ecclesiastical contexts.
