This document discusses Northrup Frye's four literary modes - romance, comedy, mimetic/realism, and tragedy/irony - which are symbolized by the four seasons. Romance is associated with spring and involves an exaggerated quest narrative. Comedy, linked with summer, has an optimistic tone and happy ending. Mimetic/realism, tied to autumn, depicts reality in a less idealized way. Tragedy/irony, connected to winter, features pessimism, darkness and death. The document provides examples of works that fit each mode and transition between them. It also examines how different genres like picaresque novels employ humor within the four modes framework.
