The principles of astrological geomancy the art of divining

This manual explains geomancy as a system of divination that combines astrological correspondences with a structured method of generating answers from marks and figures. It is historically significant as part of the long European tradition of practical divinatory arts; readers will find rules, charts, interpretive methods, and instructions for making judgments from geomantic figures.
