This document summarizes some of the main theorists of narrative theory, including Claude Levi-Strauss, Tzvetan Todorov, Vladimir Propp, and Roland Barthes. It explains that Levi-Strauss believed stories operate according to binary opposites, while Todorov thought stories happened in certain stages. Propp analyzed Russian fairy tales and proposed they involved characters filling roles like hero, villain, and donor. Barthes suggested narratives have five codes that help readers make sense of them, such as action, symbolic, and cultural codes.
