A photo sometimes said to depict members of Chiloé’s murderous society of warlocks—founded, so they claimed, in 1786 and destroyed by the great trial of 1880-81.
When the Sect needs a new Invunche, the Council of the Cave orders a Member to steal a boy child from six months to a year old. The Deformer, a permanent resident of the Cave, starts work at once. He disjoints the arms and legs and the hands and feet. Then begins the delicate task of altering the position of the head. Day after day, and for hours at a stretch, he twists the head with a tourniquet until it has rotated through an angle of 180, that is until the child can look straight down the line of its own vertebrae.
There remains one last operation, for which another specialist is needed. At full moon, the child is laid on a work-bench, lashed down with its head covered in a bag. The specialist cuts a deep incision under the right shoulder blade. Into the hole he inserts the right arm and sews up the wound with thread taken from the neck of a ewe. When it has healed the Invunche is complete.
The world’s last great witch trial took place as recently as 1880. It was held on the remote Chilean island of Chiloé, and featured remarkable allegations of mass murder, child mutilation and sorcery, all committed in the name of a strange sort of alternative government known as La Provincia Recta – ‘The Righteous Province’ – a sect of warlocks, based in a hidden cave and given to flying about the island wearing magical waistcoats stitched from the flayed skin of the recently deceased.
The native Chilotes believed these warlocks had real powers. Bruce Chatwin, in In Patagonia, wrote a memorable description of their rites and rituals. (And fans of Swamp Thing era Alan Moore will spot the source of one of his more disturbing plots.) But – truly unusual though the story is, was it ever rooted in reality? This week’s Smithsonian essay explores the evidence. But it’s not for the faint-hearted.
