In the regular ecclesiastical courts the practice was maintained. When the Council of Constance, in its futile efforts at reformation, prepared an elaborate code of discipline, it proposed strenuous regulations to correct the all-pervading vice of simony. To prevent the sale of benefices this project of law decreed deprivation of all preferment as the punishment for such offences, and as transactions of the kind were commonly accomplished in secret, it ordained that common report should be sufficient for conviction; yet it nullified the regulation by permitting the accused to clear himself by canonical purgation.[256] Towards the close of the fifteenth century, Angelo da Chiavasco describes it as customary where there is no formal accuser and yet public rumor requires action, although the judge can also order it in cases of accusation: if the defendant fails of his purgation in the latter case he is to be punished as provided for his crime; if there is only rumor, then the penalty is discretional.[257] The judge determined the number of conjurators, who were all to be of good reputation and familiar with the life of the accused; if he were a monk, they ought if possible to be of the same order; they simply swore to their belief in his oath of denial.[258] A century later Lancelotti speaks of compurgation as the only mode of defence then in use in doubtful cases, where the evidence was insufficient.[259] This applied not only to cases between churchmen, but also to secular matters subject to ecclesiastical jurisdiction. Grillandus, writing about 1530, speaks of six conjurators of the kindred as the customary formula in proceedings for nullity of marriage, and mentions an instance personally known to him, wherein this procedure was successfully adopted by a wife desirous of a divorce from her husband who for three years had been rendered impotent by witchcraft, in accordance with the rules laid down in the canon law for such cases.[260] And among certain orders of monks within the last century, questions arising between themselves were settled by this mode of trial.[261] In England, after the Anglican Church had received its final shape under Cranmer, during the reign of Edward VI., the custom appears in a carefully compiled body of ecclesiastical law, of which the formal adoption was only prevented accidentally by the untimely death of the young king. By this, a man accused of a charge resting on presumptions and incompletely proved, was required to clear himself with four compurgators of his own rank, who swore, as provided in the decretals of Innocent III., to their belief in his innocence.[262] CHAPTER VIII.
