In "Mystics of the Renaissance," Rudolf Steiner examines the thought of eleven European mystics (Eckhart, Tauler, Suso, Ruysbroek, Nicholas of Cusa, Agrippa von Nettesheim, Paracelsus, Weigel, Boehme, Giordano Bruno, and Angelus Silesius) through a collection of essays and explains their ideas and how they relate to modern concepts.
