An allegory is a narrative technique in which characters, events, and details symbolize deeper meanings or moral lessons. It often conveys complex ideas through simple stories, making it easier for readers to grasp abstract concepts. For example, George Orwell's "Animal Farm" uses farm animals to represent the rise of totalitarianism. Allegories can be found in various forms of literature, art, and film. They encourage readers to think critically about the underlying messages and themes. A well-known example is Plato's Allegory of the Cave, which illustrates the difference between perception and reality, prompting reflection on knowledge and enlightenment.
