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.
Determined to make him confess not only the crimes which He had committed, but those also of which He was innocent, the Inquisitors began their examination.

Though dreading the tortures, as He dreaded death still more which would consign him to eternal torments, the Abbot asserted his purity in a voice bold and resolute.
