If you spot an error, have a suggestion, or just want to say hello — we’d love to hear from you.
Ryff, Walther Hermann · 1548

An elegant and learned discussion, wonderfully useful and necessary for knowing the more secret effects of nature.
Also a letter of an uncertain author concerning Incantation, Conjuration, and the suspension of the neck, together with the apologetic letter etc. of JOHN TRITHEMIUS, ABBOT OF SPANHEIM, a most learned man and a most skillful investigator of the occult philosophy and magical arts, in his books of Steganography.
BY WHICH all the Plinian difficulties, especially those of a magical nature, are explained and resolved, extracted with singular diligence from certain authors and most ancient monuments.
