Roland Barthes was a French literary theorist, philosopher, critic, and semiotician born in 1915 who died in 1980. He explored diverse fields and influenced the development of schools. Barthes believed that a text is like a "galaxy of signifiers" with no single entrance or structure, and that its meaning is derived from the infinite codes and sign systems used, rather than a fixed structure. He identified five codes that are woven into any narrative: the hermeneutic code of mystery, the proairetic code of tension, the semantic code of connotation, the symbolic code of deeper meaning from symbols, and the cultural code of wider cultural knowledge.
