The representation of orality in Mau Tempo no Canal has been critically one of the most neglected aspects of the famous novel. This study concentrates on one of the most fertile examples of the subject under focus here: the embedded stories narrated by main characters as well as secondary characters, such as the story told by Mariana Caçoa. The thesis defended here is that the embedded story narrated by this character – the story of the nun Rosinha da Glória – attains in the novel the status of mise en abyme and contributes significantly to a(n) (re)evaluation of the ideology of Mau Tempo no Canal.
