Key Differences

A prologue serves as an introduction to a story, often providing background information, setting the tone, or presenting a narrative perspective. A prequel is a separate work, usually a book, movie, or play, that narratively precedes an existing work, exploring events that occurred before the original story.
Typically, a prologue is part of the same work it introduces, not a standalone piece. Prequels are distinct entities, though they are connected to the original work through their shared universe or characters.
Prologues are common in novels, plays, and operas, where they set the stage for the main narrative. Prequels are often seen in film and literature series, providing backstory and depth to the fictional universe.
The length of a prologue is usually brief, focusing on essential information relevant to the following story. Prequels can vary in length, often being as extensive as the original work, developing characters and plot lines leading up to the initial story.
The purpose of a prologue is to enhance the understanding and enjoyment of the main work. The purpose of a prequel is to expand the narrative universe and deepen the audience's engagement with the storyline and characters.
