During the later Middle Ages people became increasingly obsessed with vision, visual analogies and the possibility of visual error. In this book Dallas Denery addresses the question of what medieval men and women thought it meant to see themselves and others in relation to the world and to God. Exploring the writings of Roger Bacon, Duns Scotus, Peter Aureol and Nicholas of Autrecourt in light of an assortment of popular religious guides for preachers, confessors and penitents, including Peter of Limoges' Treatise on the Moral Eye, he illustrates how the question preoccupied medieval men and women on both an intellectual and practical level. This book offers a unique interdisciplinary examination of the interplay between religious life, perspectivist optics and theology. Denery presents significant new insights into the medieval psyche and conception of the self, ensuring that this book will appeal to historians of medieval science and those of medieval religious life and theology.

Giordano Bruno was burnt at the stake in Rome in 1600, accused of heresy by the Inquisition. His life took him from Italy to Northern Europe and England, and finally to Venice, where he was arrested. His six dialogues in Italian, which today are considered a turning point towards the philosophy and science of the modern world, were written during his visit to Elizabethan London, as a gentleman attendant to the French Ambassador, Michel de Castelnau. He died refusing to recant views which he defined as philosophical rather than theological, and for which he claimed liberty of expression. The papers in this volume derive from a conference held in London to commemorate the 400th anniversary of Bruno's death. A number focus specifically on his experience in England, while others look at the Italian context of his thought and his impact upon others. Together they constitute a major new survey of the range of Bruno's philosophical activity, as well as evaluating his use of earlier cultural traditions and his influence on both contemporary and more modern themes and trends.
