Raven Grimassi is among the pioneering authors of the modern witchcraft renaissance. In What We Knew in the Night, he presents a cohesive and complete system of witchcraft based on traditional sources. The author's premise is that, beginning in the 1980s, with the rise of modern metaphysical publishing, authors began presenting very personal witchcraft practices. In the process, traditional and formerly well-established practices fell into obscurity, which potentially lead to confusion. What We Knew in the Night uncovers and clarifies those buried gems for a new generation, assembling and integrating key components of witchcraft, past and present. Grimassi lays out key mystical and practical foundations of witchcraft and restores their important role.
