Volume 9 of 14. The 16th Century: Intellectual Conditions and Characteristics of the 16th Century through Thomas Erastus. The aim of this set is to treat the history of magic and experimental science and their relations to Christian thought during the first thirteen centuries of our era, with special emphasis upon the 12th and 13th centuries. Magic is understood under the broadest sense of the work, as including all occult arts and sciences, superstitions and folklore. The author believes that magic and experimental science have been connected in their development, and within these pages will attempt to prove the same.
