The woman was placed within it, her hands and feet secured by driving nails through them.
The executioner placed a small thorn bush upon her face.
He positioned the glowing iron rod beside the wooden stave, and as one of his assistants hammered the rod in, the other assistant emptied a trough of earth upon the woman's head.
It is said that a scream was heard, and that the earth actually moved upwards for a moment, before all was over.
Joseph Pitton de Tournefort, travelling on botanical research in the Levant 1700–1702, observed both ordinary longitudinal impalement, but also a method called "gaunching", in which the condemned is hoisted up by means of a rope over a bed of sharp metal hooks.
He is then released, and depending on how the hooks enter his body, he may survive in impaled condition for a few days. A large iron hook was fixed on the horizontal cross-bar of the gallows and the individual was forced upon this hook, piercing him from the abdomen through his back, so that he hung from it, hands, feet and head downward.
On top of the cross bar, the executioner situated himself and performed various torture on the impaled man below him.
While gaunching as de Tournefort describes involves the erection of a scaffold, it seems that in the city of Algiers, hooks were embedded in the city walls, and on occasion, people were thrown upon them from the battlements. but the Moors and Arabs are either impaled for the same crime, or else they are hung up by the neck, over the battlements of the city walls, or else they are thrown upon the chingan or hooks that are fixed all over the walls below, where sometimes they break from one hook to another, and hang in the most exquisite torments, thirty or forty hours.
Possibility of this method was tested on an episode of Myth Busters, and confirmed.
In the late Isin/Larsa period, from about the same time, it seems that, in some city states, mere adultery on the wife's part (without murder of her husband mentioned) could be punished by impalement.
Taken captive in 1596, the barber-surgeon William Davies relates something of the heights involved when thrown upon hooks (although it is somewhat unclear if this relates specifically to the city of Algiers, or elsewhere in the Barbary States): "Their ganshing is after this manner: he sitteth upon a wall, being five fathoms high, within two fathoms of the top of the wall; right under the place where he sits, is a strong iron hook fastened, being very sharp; then he is thrust off the wall upon this hook, with some part of his body, and there he hangeth, sometimes two or three days, before he dieth." Davies adds that "these deaths are very seldom", but that he had personally witnessed it.
