Prologue

A prologue is an opening section of a literary work that precedes the main narrative. It serves to introduce setting, background, or themes and may establish the tone, perspective, or stakes of the story before the central action begins.

The term derives from Greek prologos, meaning "before the word" or "before speech," from pro- "before" and logos "word." In classical drama the prologue was a short speech or scene, often delivered by a character or the chorus to frame the plot.

A prologue is part of the work itself, unlike a foreword or preface, which are typically written by someone other than the author and placed at the front for reader orientation. In prose, a prologue may present events that occur before the main timeline or provide an overview that is not integrated into the narrative proper; in drama, it can be a direct address to the audience.

Functions include supplying backstory, clarifying context, or foreshadowing events. Prologues can be expository, dramatic, or poetic, and they may unfold nonlinearly or as a frame that situates the main story within a larger context.

Usage varies by genre and author. Some notable examples use prologues to hint at mystery or to locate a different time or place than the main narration. Critics sometimes debate their utility, arguing they can slow momentum, while supporters view them as valuable setup or mood management. Some readers choose to skip prologues.
