ON THE SHADOW OF THE IDEAS: Comprising an art of investigating, discovering, judging, ordering, and applying, set forth for the purpose of inner writing, and not for vulgar operations of memory.by Giordano Bruno translated by John Michael GreerLOST SECRETS OF THE ART OF MEMORYOne of the forgotten traditions of Western occultism, the Art of Memory was a set of disciplines dating from ancient times that enabled the scholars and mages of the Renaissance to upgrade their own brains, storing vast amounts of data in their own memories. In 1592, Giordano Bruno, the greatest master of the Art of Memory, published the secrets of his advanced version of the Art in an enigmatic Latin text. Now noted occult scholar John Michael Greer has translated the entire text of "On the Shadows of the Ideas", and provided it with an introduction, detailed notes, examples of Bruno's memory images, and a detailed guide to practical work with his system.
