Though far from definitive, a fun read nonetheless, especially for the broomstick sodomy peeps out there.
Part rehash of the evolution of the stereotype of witches and satanic orgies, part account of the nebulous mentions of weird potions and things, Hatsis tries to delve into the primary source material to see if, in fact, our well-intentioned magical ancestors were, well, tripping balls. Walking a thin line between individual (read: recreational) drug use and sheer, orgy-hopping, demonic analingus diabolery, the extant documents paint a hazy picture, but Hatsis does his best to steer through the murk.
It would seem there were a ripe number of botanical sources for medieval trips and Hatsis details these nicely, showing how knowledge of them might have persisted, perhaps even originating in some obscure shamanic past, and detailing how they came to be associated with witchcraft during that craze. Where he falls short, and needn't have, was trying to wrap all this up with a new overarching way of thinking of potions, ointments and unguents. If folks weren't covering broomsticks with satanic goo and the masturbating with them, then what were they doing with these things? There are certainly enough other sources indicating that they might very well have been some sort of ritual holdover and it would've been nice to see Hatsis go into that a little more.
Anyway, overall an often funny and interesting book, singular for the theme.
