An ancient Persian method of execution where a person is stripped naked and placed in a tree trunk with only the head, hands, and feet protruding. They are then force-fed milk and honey until they develop a severe case of diarrhea.
All of the there exposed skin would then be covered in honey to attract insects while they were left floating in a stagnant pond. As the person’s feces accumulated, the insects it attracted would begin to eat and breed within his/her skin which would become increasingly gangrenous. Death could take over 2 weeks and was likely the result of starvation, dehydration, and shock.
Conceived in the late 1700′s this was one of the first methods of execution created under the assumption that capital punishment was intended to end life rather than inflict pain (successor to #11). Although it was specifically invented as a human form of execution it has been outlawed in France and the last one was in 1977.
