Herr Lirtzen was then bound to a St.Andrew's cross, loosely fixed in the floor and beaten.
He was then fastened in a metal witch's chair under which a fire was burning. A jagged iron collar around his neck, with four iron rings, from each of which ropes stretched to the corners of the room.The ropes were shaken and pulled so that the collar lacerated the neck. After continuous torture for twenty-four hours, he still refused to bear
false witness. Two days later, he was burnt alive.
