Eventually he realized the truth. As punishment for this scandal, four Dominicans were burned at the stake by order of Pope Julius II with an audience of 30,000 people on May 1, 1509.[https://books.google.com/books?id=h_BMAQAAMAAJ&pg=PA217&dq History of the Great Reformation of the Sixteenth Century in Germany], Jean Henri Merle d'Aubigné, Philadelphia: Porter & Coates, 1870
