Dan Attrell (MA) gives a talk on the use of psychoactive substances in the Picatrix, an infamous work of medieval magic which was vital to the occult traditions of the European Renaissance and played a key role in the development of renaissance demonology and astrology.This talk entitled "High Times: Astral Magic and the Curious World of Psychotropic Substances in the Picatrix" was first presented at Western Michigan University's 48th International Congress on Medieval Studies in May 2013 in a session run by the Societas Magicka. It has since been re-recorded for a larger audience. Visit http://www.themodernhermeticist.wordpress.com for more information and for other lectures by Dan Attrell
