Austin Osman Spare was an English artist who developed idiosyncratic magical techniques including automatic writing, automatic drawing and sigilization based on his theories of the relationship between the conscious and unconscious self. His artistic work is characterized by skilled draughtsmanship exhibiting a complete mastery of the use of the line[1], and often employs monstrous or fantastic magical and sexual imagery.
Some of Spare's techniques, particularly the use of sigils and the creation of an "alphabet of desire" were adopted, adapted and popularized by Peter J. Carroll in the work
Liber Null & Psychonaut
. Carroll and other writers such as Ray Sherwin are seen as key figures in the emergence of some of Spare's ideas and techniques as a part of a magical movement loosely referred to as Chaos magic.
