Die Mystik in der Nussschale Rezeption und Einordnung des Buchs von geistlicher Armut in der Bibliothek der Erfurter Kartause

Abstract
This paper investigates the reception of the mystical German treatise known as the ‘Book of Spiritual Poverty’ in the Charterhouse of Erfurt in the late 15th century. The main resources for this investigation are the book’s entry in the local library catalogue as well as the very manuscript this entry refers to. A juxtaposition of the two allows for detailed insights into what the Carthusians of Erfurt thought about this mysterious text, whose religious background and nature have puzzled scholars since the 19th century. The main points of this investigation are the book’s peculiar title ‘Der Kern’, which appears exclusively in Erfurt, as well as its Latin commentary and its placing within the sophisticated order of knowledge on which the library itself was predicated.
