This document outlines Northrop Frye's theory of archetypal criticism, which examines common patterns and symbols in literature that are derived from myths and rituals. Frye discusses two types of criticism - meaningful criticism that analyzes archetypes using tools from philosophy and history, and meaningless criticism. He also describes the inductive and deductive methods of archetypal criticism, where the inductive method uses specific examples to identify common themes and the deductive method examines how individual works fit into overarching patterns and phases of myth.
