There were other ordeals among the Jews in the name of the Lord; as, for example, the waters of jealousy. A woman suspected of adultery was obliged to drink of that water mixed with ashes, and consecrated by the high priest. If she was guilty she instantly swelled and died. It is upon the foundation of this law that the whole Christian world in the West established oracles for persons under juridical accusation, not considering that what was ordained even by God Himself in the Old Testament was nothing more or less than an absurd superstition in the New. Duel by wager of battle was one of those ordeals, and lasted down to the sixteenth century. He who killed his adversary was always in the right. The most dreadful of all these curious and barbarous ordeals, was that of a man's carrying a bar of red-hot iron to the distance of nine paces without burning himself. Accordingly, the history of the middle ages, fabulous as it is, does not record any instance of this ordeal, nor of that which consisted in walking over nine burning ploughshares. All the others might be doubted, or the deceptions and tricks employed in relation to them to deceive the judges might be easily explained. It was very easy, for example, to appear to pass through the trial of boiling water without injury; a vessel might be produced half full of cold water, into which the judicial boiling water might be put; and the accused might safely plunge his arm up to the elbow in the lukewarm mixture, and take up from the bottom the sacred blessed ring that had been thrown into it for that purpose. Oil might be made to boil with water; the oil begins to rise and appears to boil when the water begins to simmer, and the oil at that time has acquired but a small degree of heat. In such circumstances, a man seems to plunge his hand into boiling water; but, in fact, moistens it with the harmless oil, which preserves it from contact with and injury by the water. A champion may easily, by degrees, harden and habituate himself to holding, for a few seconds, a ring that has been thrown into the fire, without any very striking or painful marks of burning. To pass between two fires without being scorched is no very extraordinary proof of skill or address, when the movement is made with great rapidity and the face and hands are well rubbed with ointment. It is thus that the formidable Peter Aldobrandini, or "The Fiery Peter," as he was called, used to manage--if there is any truth in his history--when he passed between two blazing fires at Florence, in order to demonstrate, with God's help, that his archbishop was a knave and debauchee. O, charlatans! charlatans! henceforth disappear forever from the pages of history!
