This document discusses several narrative theorists and their contributions to understanding narrative structure. Vladimir Propp analyzed Russian fairytales and proposed that narratives can be classified based on character roles such as hero, villain, and princess. Tzvetan Todorov suggested that most narratives follow a disruption-fight-return to equilibrium structure. Roland Barthes identified five codes that enable readers to make sense of narratives, including action and enigma devices. Claude Levi-Strauss examined how stories unconsciously reflect the culture they come from through symbolic oppositions.
