SOTHIS: A MAGAZINE OF THE NEW AEON, was a print spiritual magazine produced in 1970s London and Mike Magee was co-editor of this very influential publication. Sadly, it only lasted through seven editions before its outstanding success made its contributors give it up! Copies are now very hard to find. The Book of the Brazen Angel is taken from an article by Mike Magee which appeared in Sothis Vol II, Number 2 titled THE SUBSTANCE OF LUST. In the article, Mike explores the models of the universe from a diverse range of cultures and belief systems. He then goes on to explain the system of the Brazen Angel, its Grimoire and Geomancy, a system devised from a series of experiments conducted in 1974.
