Judicial torture was not the medieval barbarism popular imagination makes it out to be. It was a legal instrument built by sophisticated states and run according to strict procedure, complete with warrants, appeals, and notaries recording every scream. The story begins roughly 4,000 years ago, when governments first decided that a person’s body could be used to determine the truth. Around 2100 BC, the Sumerian Code of Ur-Nammu, the oldest surviving law code, already contained the founding idea.
A man accused of sorcery was thrown into the river, and survival meant he was innocent, with his accuser owing him three shekels of silver. Hammurabi’s famous code, several centuries later, kept the river but raised the stakes dramatically. Its second law decreed that an accused sorcerer thrown into the river who drowned was guilty, and his accuser inherited his house; if he survived, the accuser was executed and the accused received the accuser’s house. Mesopotamians even worshipped a god of the ordeal, Idlu-gugu, literally the river that confronts man.
Judges used the test only as a last resort when no witnesses or evidence existed. It functioned as humanity’s first lie detector, a machine that took a person in and returned a verdict. Egypt provides the first fully documented torture interrogations. Around 1110 BC, the Abbott Papyrus records an investigation into the looting of royal tombs at Thebes.
It includes a turf war between two mayors, one of whom was responsible for guarding the very necropolis being robbed. The interrogations used the bastinado, beating the soles of the feet with rods. The stonemason Amenpanefer confessed word for word, admitting he and seven colleagues had tunneled into a pyramid, stripped 160 deben of gold, and split the loot, and that he had previously been arrested and bribed his way out. The same papyrus records system failures, a coppersmith named Pekaru was beaten and marched to point out tombs he could not identify, witnesses were tortured including a woman and a child, and five suspects were examined and released as innocent.
The earliest records already contain the full future of the practice: confessions, acquittals, and beatings over crimes that could not be proven. Assyria took a different approach. Pain there was about messaging, not truth. King Ashurnasirpal II boasted in inscriptions about flaying rebellious chiefs and covering pillars with their skins.
A century later, Ashurbanipal decorated his palace with stone reliefs showing prisoners being skinned alive and having their tongues removed, placed directly in the path of visiting ambassadors. Scholars have calculated that roughly 35 percent of all known atrocity scenes from the entire Neo-Assyrian period come from just this one king’s reign, and several historians believe the atrocities were exaggerated for psychological effect, making some of history’s most infamous torture inflated propaganda. The Middle Assyrian law tablets also allowed a husband to whip his wife, tear out her hair, and mutilate her ears with no legal penalty. In Athens, torture received its intellectual justification.
In classical courts, a slave’s testimony was admissible only if extracted under torture, on the logic that pain had to outweigh loyalty. The word used was basanos, literally the touchstone, named after quality control. Yet scholars have counted 42 formal challenges to torture slaves in surviving court speeches, and all were refused or never carried out. Athenian torture was mostly a rhetorical bluff.
Aristotle himself warned that evidence from torture was worthless, because tough people endure and say nothing while everyone else says whatever makes it stop, an argument Europe would ignore for roughly two thousand years. This era also produced the brazen bull, allegedly commissioned around 570 BC by the tyrant Phalaris of Acragas. Victims were locked inside a hollow bronze bull and burned alive, with tubes turning their screams into bellowing. The poet Pindar mentions it within a century, but no trace of any such device has ever been found, and historians suspect it was anti-tyrant propaganda.
Rome turned the Greek idea into administrative law. Under the Republic, judicial torture was for slaves only, and a citizen’s body was legally untouchable. Crucifixion was nicknamed the slaves’ punishment, and after the Spartacus revolt collapsed in 71 BC, roughly 6,000 captured rebels were crucified along the Appian Way. In AD 61, the law met reality when the prefect Pedanius Secundus was murdered by one of his own slaves, and Roman law required all 400 members of his household, including women and children, to be tortured and executed.
The Roman public rioted to stop it, surrounding the Senate with stones and torches, but the Senate sided with the senator Cassius Longinus, who argued the executions must proceed precisely because they were unjust. Emperor Nero lined the route with soldiers and all 400 died. Rome’s great jurist Ulpian wrote that torture is a fragile and dangerous thing that deceives the truth, because the strong will lie through anything and the weak will confess to anything. That warning went into the Digest, the law books European students studied for the next 1,500 years, sitting alongside the very rules for how to torture properly.
Then the practice vanished from European law for roughly 700 years. The Germanic kingdoms that replaced Rome ran an accusatorial system with no state prosecutor, so there was no job for an information-extraction tool. Accused persons could bring oath helpers who swore to their good character, and hard cases were settled by ordeals conducted as church services. An accused person carried a red-hot iron or plunged an arm into boiling water, and healing cleanly after three days meant innocence.
In the cold water ordeal, sinking meant innocence because the pure element accepted you, the exact opposite of the Babylonian reading of the same test two and a half millennia earlier. A surviving register from Varad in medieval Hungary records 208 hot iron ordeals between 1208 and 1235, with about two out of three people passing the test by carrying scalding metal. In November 1215, the Fourth Lateran Council banned priests from blessing ordeals, and the system collapsed within a generation. England replaced it with the trial jury.
The continent chose something else: a revival of Roman law with a rule that changed everything. To convict someone of a capital crime, a court needed either two eyewitnesses or a confession, and circumstantial evidence, no matter how damning, was legally insufficient. Jurists called confession the queen of proofs, and since most crimes do not produce two eyewitnesses, the system depended entirely on confessions. Torture returned not as barbarism but as a legal workaround, written by lawyers for lawyers and appearing in Italian city statutes beginning at Verona in 1228.
The procedure had strict rules. A judge needed half proof, one eyewitness or strong evidence, before issuing a formal torture warrant, which in some jurisdictions could be appealed. Emperor Charles V’s criminal code of 1532 banned leading questions. A confession made under torture was legally worthless on its own and had to be repeated freely a day later.
Jurists generally allowed three rounds, and there were exemptions for children, pregnant women, the elderly, and nobles. The standard instrument was the strappado, wrists tied behind the back and hoisted by a pulley, agonizing, bloodless, and leaving no visible maiming. Through it all, a notary sat recording every question, answer, and shout, which is why historians can reconstruct these sessions today. England skipped most of this because English juries could convict on circumstantial evidence, so torture never became part of common law procedure.
When the English state wanted it, officials used royal warrants, just 81 total between 1540 and 1640, almost all for treason and almost all carried out in the Tower of London. In 1628, after John Felton assassinated the Duke of Buckingham, the common law judges ruled unanimously that torture was illegal under English law. The last warrant came in 1640. The carefully built system had an off switch, and it was labeled witchcraft.
Witchcraft was a crime so extreme that normal safeguards were suspended, and the confession script required suspects to name people they had seen at the witches’ sabbath. Every tortured suspect produced names, every name led to a new arrest, and every arrest produced more names. Torture was manufacturing the entire evidence supply. England, without judicial torture, had comparatively small witch hunts and almost no sabbath confessions, while the German Prince-Bishoprics with unrestricted torture produced catastrophes.
Würzburg, from 1626 to 1631, saw an estimated 900 dead. The mayor of Bamberg, Johannes Junius, was told by his own jailer to confess something, anything, since torture would continue until he said he was a witch. He wrote to his daughter from prison, innocent have I come into prison, innocent have I been tortured, innocent must I die, before his execution in August 1628. The Jesuit priest Friedrich Spee, who accompanied condemned witches to the stake, published Cautio Criminalis in 1631 showing the system offered the innocent no exit at all.
The standard story credits the Enlightenment for abolishing torture, but according to legal historian John Langbein, that is a fairy tale. Frederick the Great abolished torture in Prussia in 1740, a full 24 years before Beccaria’s On Crimes and Punishments appeared. By the 1600s, courts had developed new punishments and a doctrine allowing conviction on strong circumstantial evidence when imposing lesser sentences. Once judges could convict without a confession, torture had no remaining function.
The philosophers wrote the obituary for a machine the lawyers had already unplugged. Beccaria’s book still made abolition a moral fashion, and it spread quickly across Sweden, Austria, France, and the rest of Western Europe by 1831. As for the famous museum devices, the iron maiden was invented as a hoax in 1793. The pair of anguish appears in no period source, its spring mechanism was beyond medieval metallurgy, and surviving examples cannot even open.
The Victorians built a fake medieval hellscape to feel modern. The real instruments were a rope, a pulley, a signed warrant, and a notary writing he screamed in the margin.
