Confession by Torture: Witchcraft, Fear and the Destruction of Geillis Duncan
Geillis Duncan occupies a grim and pivotal place in British history. She is remembered as the first self-confessed witch in Scotland. That word, confessed, matters. It suggests choice. In truth, her confession was forced from her body through calculated, degrading, and relentless torture.
What followed her broken admission did not end with her death. It spread outward, south into England and beyond.
Geillis did not create the witch panic, however, she became the moment it found its voice in Scotland.
A World That Was Ready to Believe
By the late sixteenth century, Europe was already primed for witch-hunting. Failed harvests, recurring plague, infant mortality, and violent storms created a population desperate for explanation. Protestant reform had stripped away older religious comforts. God felt distant but the Devil felt closer.
Witchcraft provided a human cause for suffering, it offered someone to blame.
That belief had been sharpened by the book, Malleus Maleficarum, first published in 1487 and still widely read a century later (it is still in print and easily found today).
The book asserted that witches were real, organised, sexually depraved, in league with Satan and they were overwhelmingly female. It described, in obsessive detail, how witches were said to renounce God, copulate with demons, murder children, and destroy crops. Most dangerously, it gave legal and moral permission to torture. Pain, it argued, revealed truth.
By the time poor Geillis Duncan was accused, torture was not an aberration – it was procedure.
A Maid With Too Much Knowledge
Geillis Duncan was a young maidservant in Edinburgh, employed by a man of status and means. She was poor, female, and socially powerless. These traits were not incidental, they made her vulnerable.
She had a reputation for curing ailments. Under her care, sick animals recovered while people improved after she tended them. In another age, this might have earned respect but in 1590s Scotland, it provoked suspicion.
Her employer accused her of witchcraft when she could not adequately explain how she has the power of healing. There was no illness she was said to cause, no crime witnessed. Her ability alone was enough to condemn her.
Geillis was imprisoned.
Torture as Investigation
At first, Geillis denied everything but that refusal triggered escalation.
Her interrogators subjected her to prolonged sleep deprivation, keeping her awake for days until hallucinations blurred her sense of reality.
Her hair was shaved from her entire body. This was not hygiene but purely humiliation, intended to strip her of dignity and resistance.
Then came the physical torture.
Her thumbs were crushed in iron screws. Pressure was increased slowly, deliberately, until bones strained and splintered, nails and skin split, and pain became all-consuming.
This was repeated, again and again, until resistance collapsed.
Her already punished body was searched inch by inch for the Devil’s mark, a supposed blemish that did not bleed or feel pain. Pins were driven deep into her skin.
Worse was yet to come. Geillis was also tortured by a method known as wrenching, a deliberately crippling practice designed to force confession rather than discover truth. Her head and limbs were bound and violently twisted beyond their natural range, often using cords, ropes, iron bars, or the leverage of multiple men pulling in opposite directions.
Joints were partially dislocated, muscles tore, and ligaments stretched or snapped, sending waves of white-hot pain through the body. The skull would be squeezed until it fractured and split and bones in the face and jaw would break. The damage was not always immediately fatal, but it left indescribable agony, lasting injury, swelling, numbness, and an overwhelming sense of bodily betrayal.
Wrenching broke the body slowly, making survival itself feel conditional on obedience, until agreement with one’s abusers became an instinctive attempt to stop the agony.
At some point, Geillis Duncan broke.
She confessed!
The Confession That Changed Everything
Geillis’s confession was detailed, lurid, and impossible. She described meetings with the Devil, appearing as a black man.
She spoke of night gatherings with other witches, dancing, and conspiracies against the king. She admitted to raising storms through incantation and bone charms.
None of this came from memory, it came from expectation. Torture teaches its victims what their captors want to hear.
Her confession made her the first recorded self-confessed witch in Scotland. It also transformed suspicion into certainty.
If one witch existed, others must too. In fact, the utterly ravaged Geillis would be forced to implicate others as witches in an attempt to end the violent attentions of her oppressors.
The North Berwick Witch Trials
Geillis’s words triggered the North Berwick witch trials, one of the largest and most consequential witch-hunts in Scottish history. Dozens were accused, many were tortured, several were executed.
Confessions began to mirror one another, not because they were true, but because interrogators fed details into the questioning. Accused witches repeated the same phrases, the same crimes, the same devilish rituals. This repetition was taken as corroboration.
A King Who Believed
At the centre of this hysteria stood King James I, then James VI of Scotland. He did not merely endorse the trials but involved himself personally.
James believed witches had attempted to kill his new bride and Queen, Anne of Denmark. He thought witchcraft had raised storms as her ship crossed the North Sea to meet him, almost sinking it and drowning her but the storms had forced Queen Anne to turn back. This is why James took witchcraft so personally and why he questioned the accused directly, interpreting their tortured confessions as proof of a vast, organised threat.
In 1597, James published Daemonologie, a book that insisted witches were real, malevolent, and enemies of both God and crown. It rejected scepticism and encouraged vigilance.
When James inherited the English throne in 1603, his beliefs crossed the border with him.
Fear Moves South
Under James’ rule, English witch laws hardened while accusations increased. The idea of witches as conspirators against the state took hold. Clergy preached sermons warning of Satan’s agents among the population. Magistrates adopted Scottish methods of interrogation.
While England did not embrace torture as openly as Scotland, coercion remained common. Imprisonment, deprivation, threats, and public pressure broke many accused people just as effectively.
The panic did not stop at Britain’s borders. Similar patterns appeared across northern Europe. Scotland’s trials became part of a wider, international panic.
Geillis Duncan’s End
Geillis Duncan was convicted but the exact details of her execution are not preserved, but the method is well known.
She was likely strangled and then burned, her body reduced to ash as a warning.
She did not survive to see the damage her forced confession caused but her words, extracted under torture, outlived her.
What Her Story Reveals
Geillis Duncan was not powerful, she was not dangerous. she did not control storms or summon devils. Her only crime was to live in a world that treated fear as evidence and pain as proof.
Her story exposes how easily authority can mistake cruelty for truth, and how quickly ideology can turn suffering into spectacle.
The witch-hunts that followed were not accidents of superstition. They were systems, supported by law, religion, and monarchy.
To remember Geillis Duncan with sympathy is not sentimentality but it is accuracy.
She was not a witch… …she was the first voice broken loud enough for history to hear.
