Supernatural phenomena and causalities played an important role in medieval society.Religious practice was relying upon a set of cult images and the sacral status of these depictions of divine or supernatural persons became the object of heated debates and provoked iconoclastic reactions.The miraculous intervention of saints or other divine agents, the wondrous realities beyond understanding, or the manifestations of magic attributed to diabolic forces, were contained by a variety of discourses, described and discussed in religion, philosophy, chronicles, literature and fiction, and also in a large number of pictures and material objects.The nine essays in this collection discusses how supernatural phenomena – especially angels and devils – found visual manifestation in Latin and Eastern Christianity as well as Judaism in the late medieval, early renaissance period.
