   note: in england ordeal by fire and ordeal by water were
         used, the former confined to persons of rank, the
         latter to the common people. the ordeal by fire was
         performed, either by handling red-hot iron, or by
         walking barefoot and blindfold over red-hot plowshares,
         laid at unequal distances. if the person escaped
         unhurt, he was adjudged innocent; otherwise he was
         condemned as guilty. the ordeal by water was performed,
         either by plunging the bare arm to the elbow in boiling
         water, an escape from injury being taken as proof of
         innocence, or by casting the accused person, bound hand
         and foot, into a river or pond, when if he floated it
         was an evidence of guilt, but if he sunk he was
         acquitted. it is probable that the proverbial phrase,
         to go through fire and water, denoting severe trial or
         danger, is derived from the ordeal. see wager of
         battle, under wager.
