Fama Fraternitatis is the foremost of three texts which would go on to influence the entire Rosicrucian tradition and its offshoots. Touching on alchemy, philosophy, ethics, and religious tradition in multiple manners, this short work had one of the most powerful effects upon the occult until the era of Mathers and Crowley. Still circulated and read today, it is a powerful testament to its authors' spiritual leanings.
