How does flashback imageryand symbolism work to help convey theme in a work of literature?

Flashback imagery and symbolism can help convey theme by providing background information about characters or events, which adds depth to the narrative and allows readers to better understand the characters' motives and actions. Through symbolism, authors can convey abstract ideas or emotions, enriching the text with deeper meanings that contribute to the overall theme of the work. Together, these literary devices can create a more complex and nuanced portrayal of the central themes of the work.
