St. Peter was a Dominican friar and a popular preacher in north and central Italy in the 13th century. His reputation led him to be named an inquisitor in Lombardy. He regularly denounced heresy, especially Catharism, and also condemned Catholics who professed their faith only in word, not in actions. The Cathars were a Gnostic sect who believed that there was not one, but two gods, a good god and an evil god. A group of Milanese Cathars hired an assassin to kill him. He was struck in the head with an axe and legend has it that he rose to his knees and began reciting the Apostles Creed. He then dipped his fingers in his own blood and began to write the creed on the ground. A second blow beheaded him.
