What drew Martin Luther to the Frankfurter at first sight, an undistinguished late Medieval treatise? Starting from this question, the monograph takes us back to the 14^th century. It reveals how the Frankfurter earned its unique philosophical and theological reputation through its involvement in transformation processes within mystical discourse, making it akin to Luther's theological anthropology.
