Across Europe the convinction the corpse began to bleed in the presence of the murderer was known as "ius feretri". It was, in fact, an ordeal by which the intervention of divine power assured justice ad legal certainty. The different forms of ordeals were a means commonly used to establish the guilt or less than one person. The trust in a higher power and external assumed such strength can be a guiding principle and norrn of social relations. The "ius feretri" was applied until the 18th Century and during its Iongue durée acquired a new social-legal dimension, so that is fair to consider that this practice is not to be regarded as a classic ordeal, but as an actual social-legal practice for the achievement of legal truth and, in sorne cases, the formation of the consensus.
