By the time Map wrote this account, around 1180, such ideas had entered into the thinking even of professional philosophers and theologians. The Frenchman Alain de Lille, whose reputation for learning was such that he was nicknamed
The atmosphere was changing. Fantasies which in the early Middle Ages had been quite unknown in western Europe were turning into commonplaces. As so often, by dint of repetition fictions were coming to be accepted as fact. Certainly by the time Guillaume d’Auvergne penned his comment, some time between 1231 and 1236, he could be sure of support in the highest possible quarters; for, as we shall see, in 1233 a particularly elaborate version of the fantasy was incorporated in a papal bull.
The (not very numerous) executions of heretics during the eleventh and twelfth centuries were almost all the work of the secular authorities or of the mob; the clergy, while keenly interested in the elimination of heresy, generally relied on persuasion and were reluctant to sanction the use of force. But even then there were exceptions. In 1025 Gerard, bishop of Cambrai, was making a visitation of his diocese. At Arras a group of heretics was denounced to him; he had these people tortured and, as they showed themselves fittingly penitent, reconciled them with the Church. In 1035 Heribert, archbishop of Milan, had some heretics denounced to him at Monteforte; having interrogated them and found them impenitent, he had them burned. As Gerard II, bishop of Cambrai, was passing through a small town on a visitation in 1077, a heretic called Rhamird was denounced; after interrogation Rhamird too was burned.
These were early examples of the type of legal procedure which lawyers and legal historians call “inquisitorial”, and which stood in marked contrast to the accusatory type of procedure which was the norm throughout the Middle Ages. Whereas under the accusatory procedure the initiative in bringing a charge lay with a private individual,**
under the inquisitorial procedure it lay with the authorities. The authorities were responsible for collecting, from the public, information which might lead to the discovery of crimes and the identification of criminals. This meant that they depended on denunciations. Once armed with sufficient denunciations, the judge himself proceeded to an investigation, or “inquisition”, of the suspect.The first beginnings of this type of procedure can be traced back to Roman law as it existed under the Empire. In Roman law, as in Germanic law, the norm was the accusatory procedure — but, there were exceptions. Notably in cases of
As religious dissent spread, from the second half of the twelfth century onwards, legislation was introduced for the purpose of combating it. At the synod of Verona in 1184 Pope Lucius III and Emperor Frederick I decreed the excommunication of heretics; moreover those heretics who refused to recant, or who after recanting had relapsed, were to be relaxed to the civil power for punishment. In response to the decrees of the fourth Lateran Council in 1215, various rulers decreed the death penalty for obdurate heresy. And in 1231 Pope Gregory IX and Emperor Frederick II, acting in concert, established a coherent legislation against heretics in the Empire. For the first time the various penalties for heresy — up to and including death — were clearly formulated.
