The Decameron, Volume II

Saint Ciappelletto is the main character in chapter one. The saint begins the story as Ser Cepparello, a notary who lives in France. Cepparello is a very dishonest man to the point that he is ashamed if any of his dealings are proven to be honest and true. However, because Cepparello is such an accomplished liar, the people of his village honor the man and entrust him.
