This document discusses several narrative theorists and their perspectives on narrative structure. Vladimir Propp analyzed Russian fairy tales and identified character roles like the hero, villain, and donor. Tzvetan Todorov suggested that narratives follow a structure of equilibrium, disruption of equilibrium, recognition of disruption, attempt to repair disruption, and reinstatement of equilibrium. Roland Barthes identified five narrative codes - action, enigma, symbolic, semic, and cultural - that help readers make sense of a narrative. Claude Levi-Strauss examined how myths reflect a culture's unconscious beliefs through binary oppositions.
