Agrippa von Nettesheim 
The Philosophy Of Natural Magic 

In the last half of 1509 and the first months of 1510, Cornelius Agrippa, known in his day as a Magician, gathered together all the Mystic lore he had obtained by the energy and ardor of youth and compiled it into the elaborate system of Magic, in three books, known as Occult Philosophy, the first book of which—Natural Magic—constitutes the present volume.

This is true and sublime Occult Philosophy. To understand the mysterious influences of the intellectual world upon the celestial, and of both upon the terrestrial; and to know how to dispose and fit ourselves so as to be capable of receiving the superior operations of these worlds, whereby we may be enabled to operate wonderful things by a natural power—to discover the secret counsels of men, to increase riches, to overcome enemies, to procure the favor of men, to expel diseases, to preserve health, to prolong life, to renew youth, to foretell future events, to see and know things done many miles off, and such like as these. These things may seem incredible, yet read but the ensuing treatise and thou shalt see the possibility confirmed both by reason and example.
