This document introduces several theorists of narrative structure, including Tzvetan Todorov, Vladimir Propp, Roland Barthes, and Claude Levi-Strauss. It summarizes some of their main contributions: Todorov proposed narratives follow a structure of equilibrium, disequilibrium, and new equilibrium. Propp identified 31 narrative functions that follow a sequential order. Barthes described codes like the hermeneutic code that establish narrative mysteries. And Levi-Strauss viewed narratives as based on binary oppositions that reveal deeper ideological meanings.
