Spiritual & demonic magic

the long version

"This book takes as its subject the magical concerns and beliefs, and the demonic theories and practices, of some of the greatest thinkers of the fifteenth, sixteenth and seventeenth centuries, from Ficino, Pico della Mirandola, to Jean Bodin, Francis Bacon and Campanella.". "At a time when most scholars tended to view magic as a marginal subject. Walker showed that magic was one of the most typical creations of the late fifteenth and sixteenth centuries and that 'Spiritus' played an important role in the Renaissance. Magic was, as this book demonstrates, profoundly interconnected with religion, music and medicine."--BOOK JACKET.
