Ordeals, however, formed a method of appealing to God, the results of which could be immediately observed. A common form of ordeal was by fire. The accused walked barefoot over live brands, or stuck his hand into a flame, or carried a piece of red-hot iron for a certain distance. In the ordeal by hot water he plunged his arm into boiling water. A man established his innocence through one of these tests, if the wound healed properly after three days. The ordeal by cold water rested on the belief that pure water would reject the criminal. Hence the accused was thrown bound into a stream: if he floated he was guilty; if he sank he was innocent and had to be rescued. Though a crude method of securing justice, ordeals were doubtless useful in many instances. The real culprit would often prefer to confess, rather than incur the anger of God by submitting to the test and ordeals.
