Drawing upon Huser's 1589 publication of Paracelsus' works, this dual-language volume combines a critical edition of Essential Theoretical Writings on philosophy, medicine, nature, and the supernatural, with new English translations and extensive commentary on the second largest sixteenth-century German-language corpus.

Andrew Weeks, Professor of German at Illinois State University, with a doctorate in Comparative Literature from the University of Illinois, has published intellectual biographies of Jacob Boehme, Paracelsus, Valentin Weigel, a history of German mysticism, and translations of Weigel's writings.
