Final answer:
In literature, an epiphany is a character's moment of revelation, as illustrated in Raymond Carver's "Cathedral," when the narrator achieves a moment of deep insight while drawing a cathedral with a blind man.
Step-by-step explanation:
An epiphany in literature refers to a moment of sudden revelation or insight experienced by a character. An example of an epiphany in Raymond Carver's short story "Cathedral" occurs near the end when the narrator, who was previously unenlightened and disconnected from the people around him, shares a profound moment of understanding and connection with a blind man. They draw a cathedral together, with the narrator closing his eyes, leading him to an unexpected moment of clarity and revelation about his own existence and the way he perceives the world.
