In the modern judicial system, the innocence or guilt of an accused may be established based on the evidence brought against him or her.
In ancient and medieval societies, however, a different way of determining a person’s innocence or guilt was used. This was called the ‘trial by ordeal’.
This method involved having the accused do something dangerous or even life-threatening. If the accused survived the ordeal, he or she is (usually) proclaimed innocent. If guilty, the individual would perish.
Why the trial by ordeal was actually an effective test of guilt ?
