Inspired by the work of eminent scholar Richard Kieckhefer, The Sacred and the Sinister explores the ambiguities that made (and make) medieval religion and magic so difficult to differentiate. The essays in this collection investigate how the holy and unholy were distinguished in medieval Europe, where their characteristics diverged, and the implications of that deviation. In the Middle Ages, the natural world was understood as divinely created and infused with mysterious power. This world was accessible to human knowledge and susceptible to human manipulation through three modes of engagement: religion, magic, and science. How these ways of understanding developed in light of modern notions of rationality is an important element of ongoing scholarly conversation. As Kieckhefer has emphasized, ambiguity and ambivalence characterize medieval understandings of the divine and demonic powers at work in the world. The ten chapters in this volume focus on four main aspects of this assertion: the cult of the saints, contested devotional relationships and practices, unsettled judgments between magic and religion, and inconclusive distinctions between magic and science. Freshly insightful, this study of ambiguity between magic and religion will be of special interest to scholars in the fields of medieval studies, religious studies, European history, and the history of science. In addition to the editor, the contributors to this volume are Michael D. Bailey, Kristi Woodward Bain, Maeve B. Callan, Elizabeth Casteen, Claire Fanger, Sean L. Field, Anne M. Koenig, Katelyn Mesler, and Sophie Page.

The astrologer-physician Richard Napier (1559-1634) was not only a man of practical science and medicine but also a master of occult arts and a devout parish rector who purportedly held conversations with angels. This new interpretation of Napier reveals him to be a coherent and methodical man whose burning desire for certain, true knowledge contributed to the contemporary venture of putting existing knowledge to useful ends. Originally trained in theology and ordained as an Anglican priest, Napier later studied astrological medicine and combined astrology, religious thought, and image and ritual magic in his medical work. Ofer Hadass draws on a remarkable archive of Napier’s medical cases and religious writings—including the interviews he claimed to have held with angels—to show how Napier’s seemingly inconsistent approaches were rooted in an inclusive and coherent worldview, combining equal respect for ancient authority and for experientially derived knowledge. Napier’s endeavors exemplify the fruitful relationship between religion and science that offered a well-founded alternative to the rising mechanistic explanation of nature at the time. Carefully researched and compellingly told, Medicine, Religion, and Magic in Early Stuart England is an insightful exploration of one of the most fascinating figures at the intersection of medicine, magic, and theology in early modern England and of the healing methods employed by physicians of the era.

In 1968 University of California Press published an unusual manuscript by an anthropology student named Carlos Castaneda. The Teachings of Don Juan enthralled a generation of seekers dissatisfied with the limitations of the Western worldview. Castaneda's now classic book remains controversial for the alternative way of seeing that it presents and the revolution in cognition it demands. Whether read as ethnographic fact or creative fiction, it is the story of a remarkable journey that has left an indelible impression on the life of more than a million readers around the world.
