There is also another aspect in which it is probable that the ordeal was viewed by those whose common sense must have shrunk from it as a simple appeal to the judgment of God. There can be little doubt that it was frequently found of material use in extorting confession or unwilling testimony. By the early codes, as in the primitive Greek and Roman law, torture could be applied only to slaves, and the ordeal was a legalized torture, applied under circumstances peculiarly provocative of truth, and as such we occasionally find regulations which enable the freeman to escape by compurgation, while the slave is required to undergo the ordeal.[1251] The elaborate nature of the ritual employed, with its impressive adjurations and exorcisms, was well fitted to excite the imagination and alarm the conscience; sometimes, indeed, to render it more effective, the mass celebrated was a mortuary one, which when sung for a living man was popularly believed to possess deadly powers of peculiar efficacy.[1252] In those ages of faith, the professing Christian, conscious of guilt, must indeed have been hardened who could undergo these awful rites, pledging his salvation on his innocence, and knowing under such circumstances that the direct intervention of Heaven could alone save him from having his hand boiled to rags,[1253] after which he was to meet the full punishment of his crime, and perhaps in addition lose a member for the perjury committed. With such a prospect, all motives would conspire to lead him to a prompt and frank acknowledgment in the early stages of the proceedings against him. These views are strengthened by the fact that when, in the thirteenth century, the judicial use of torture, as a means of obtaining testimony and confession, was becoming systematized and generally employed, the ordeal was falling into desuetude and rapidly disappearing. The latter had fulfilled its mission, and the former was a substitute better fitted for an age which reasoned more, believed less, and at the same time was quite as arbitrary and cruel as its predecessor. A further confirmation of this supposition is afforded by the coincidence that the only primitive jurisprudence which excluded the ordeal—that of the Wisigoths—was likewise the only one which habitually permitted the use of torture,[1254] the only reference to the ordeal in their code being a provision which directs its employment as a preliminary to the more regular forms of torture.
