Absztrakt: The aim of this paper is to analyse the opening short story of Decameron. Here, Boccaccio plays with the reader, hiding himself behind Ser Cepparello, the main character, and giving rise to various interpretations. Does the story concern a criticism against the religious
habits and the popular naivety, or is it rather an entertainment, with the only goal of amusing the reader thanks to the power of the word? The paper reviews the most important critical
literature, and then it attempts an interpretation of Ciappelletto, who unwillingly became a Saint.
