What is a scene set in a time earlier than the main story called?

A scene set in a time earlier than the main story is termed a flashback. This narrative device allows the reader to gain insight into a character's background, motivations, or significant events that have shaped the current storyline. By using flashbacks, authors can enrich the plot and provide context that enhances the reader's understanding of characters and circumstances.

In contrast, a prologue serves as an introductory section of a story that sets the stage but is not necessarily a scene from the past. An interlude refers to a break or interruption in the narrative, often different from the timeframes being explored. Foreshadowing is a technique used to hint at future events, rather than looking back to earlier times in the story. Therefore, flashbacks play a vital role in storytelling by bridging past and present, helping to illuminate the current narrative.
