The abbot was not merely accused of rape and murder: the crime of sorcery was laid to his charge, as well as to Matilda’s. She had been seized as an accomplice in Antonia’s assassination. On searching her cell, various suspicious books and instruments were found which justified the accusation brought against her. To criminate the monk, the constellated mirror was produced, which Matilda had accidentally left in his chamber. The strange figures engraved upon it caught the attention of Don Ramirez, while searching the abbot’s cell: in consequence, he carried it away with him. It was shown to the Grand Inquisitor, who having considered it for some time, took off a small golden cross which hung at his girdle, and laid it upon the mirror. Instantly a loud noise was heard, resembling a clap of thunder, and the steel shivered into a thousand pieces. This circumstance confirmed the suspicion of the monk’s having dealt in magic: it was even supposed that his former influence over the minds of the people was entirely to be ascribed to witchcraft.
