Alphitomancy is a form of divination using barley, usually barley cakes or loaves of barley bread, to identify a guilty person. Suspects were given the bread to eat in the belief that the innocent would swallow it without harm while the guilty would choke or suffer. It is closely related to medieval ordeals by consecrated bread such as the English corsned.

Meaning and name
The word combines the Greek alphiton, barley groats or barley meal, with manteia, divination. Like many "-mancy" terms, it was coined or popularized by later scholars and compilers of lists of divinatory arts, who gathered practices from classical, medieval and folk sources and gave them learned Greek names.
Alphitomancy should not be confused with aleuromancy, divination with flour, in which messages were baked into small cakes and chosen at random. In alphitomancy the aim was not to foretell the future but to reveal hidden guilt, which makes it a practice on the border between divination and a trial by ordeal.
How it was said to work
Descriptions of the practice are brief. A group of people suspected of a crime, such as a theft, would each be given a piece of barley cake or barley bread. The belief was that the innocent would eat it without difficulty and feel well, while the guilty party would be unable to swallow, would choke, or would suffer from indigestion or visible distress.
In Christian contexts the bread was often blessed and accompanied by prayers calling on God to reveal the truth. The assumption behind the rite was that divine justice would intervene in a physical way, marking the guilty through the body.
The corsned ordeal
The best-documented relative of alphitomancy is corsned, the "ordeal by morsel" of Anglo-Saxon England. The accused had to swallow a small piece of consecrated barley bread and cheese; choking or turning pale was taken as a sign of guilt. Corsned is mentioned in the laws of King Aethelred II and of Cnut, in the early eleventh century, and was later abandoned along with other ordeals.
A famous story claims that Earl Godwin of Wessex died in 1053 after swallowing a morsel while denying involvement in the death of Alfred Aetheling. Historians treat this as legend, since it comes from sources written long after the event, including a chronicle shown to be a later forgery.
Folklore and later echoes
The idea that a person could be struck down for swearing falsely over bread survived in folk belief and oath formulas such as "may this bread choke me if I lie." Accounts of the Belvoir witch case in early seventeenth-century England report that one of the accused, Joan Flower, called for bread and wished it would choke her if she were guilty, and died shortly afterward; the story was widely retold as a sign of judgment.
Collectors of occult lore in the nineteenth and twentieth centuries included alphitomancy in their catalogues alongside other forms of divination by everyday objects and actions, such as lecanomancy (water in a basin), aspidomancy and gyromancy (walking in a circle until dizzy). Such lists often preserved only a sentence about each practice.
Modern interpretation
Historians see alphitomancy and corsned as part of the wider medieval system of ordeals, which assumed that God would reveal the truth when human proof was lacking. The Fourth Lateran Council of 1215 forbade clergy from taking part in ordeals, and such trials declined across Europe.
Some modern writers suggest that fear could produce a dry mouth and make swallowing genuinely difficult for an anxious suspect, so that the ordeal might sometimes intimidate the guilty, but it could equally condemn a frightened innocent person. There is no evidence that bread can detect guilt, and the practice survives today mainly as a historical and folkloric curiosity.
Related divination by food
Alphitomancy is one of several ancient and folk practices that used food as a medium of judgment or prophecy. Aleuromancy used flour, and in some later forms slips of paper baked into dough, an ancestor of the idea behind modern fortune cookies. Critomancy is a name given to divination from barley meal or cakes offered in sacrifice, and tyromancy to divination by cheese.
Bread held special religious weight in both pagan and Christian Europe, as the staple food, as an offering, and in Christianity as part of the Eucharist. This sacred status helps explain why a morsel of bread could be thought capable of accepting the innocent and rejecting the guilty, and why oaths sworn over bread were taken seriously.

Frequently asked questions
What is alphitomancy?
Alphitomancy is divination by barley. Suspects in a crime were given barley cakes or barley bread to eat, in the belief that the innocent could swallow it easily while the guilty would choke or suffer indigestion. The name comes from the Greek alphiton, meaning barley, and manteia, meaning divination.
What is the difference between alphitomancy and corsned?
They are closely related. Alphitomancy is the general name for detecting guilt with barley bread. Corsned was a specific legal ordeal in Anglo-Saxon England, mentioned in the laws of Aethelred II and Cnut, in which the accused swallowed consecrated bread and cheese, and choking was taken as proof of guilt.
Is alphitomancy still practiced?
Not in any organized way. Ordeals were condemned by the church from 1215 onward and disappeared from European law. Alphitomancy is now mainly a historical and folkloric topic, though sayings like "may this bread choke me" preserve echoes of it. There is no evidence that eating bread can reveal a person's guilt.
