" Prophecy " and " fable " were two different concepts. Prophecy usually referred to an accurate prediction or description of the future or an event at a specific time or place through a certain method or means. These predictions or descriptions were usually based on known facts, historical events, or other information through some kind of logical or inferential method. In novels, prophecy was often used to show the author's wisdom or prediction ability, or to guide the reader to think about the future development trend. Fable was a fictional story that expressed a profound idea or truth by telling a story related to the real world. Fables were usually simple stories that described animals, plants, people, or other things. They often had a certain symbolic meaning. The purpose of fables was to convey certain ideas or principles through stories rather than to predict the future or describe facts. Although both prophecies and fables were fictional stories, the former usually focused more on predicting the future or describing facts, while the latter focused more on expressing certain ideas or principles.
