The Bones Go Last is a short documentary centered around Austin Osman Spare, a British artist and devout practitioner of Occultism, whose esoteric ideas became instrumental for the development of Chaos Magick, and influenced other artist/magicians like Alan Moore and Grant Morrison.
Alas, the documentary doesn’t really delve much into Spare’s occultism, beyond his brief romantic involvement with The Beast himself, Aleister Crowley. Which is why I recommend you head out to Ultraculture and read Jason Louv’s article where he does explore Spare’s work with sigils, as well as his autumn friendship with Kenneth Grant, who is largely responsible for Spare’s popularity in current esoteric circles.
A much enviable talent; though certainly not an enviable life…
