While most people think of myths as fables (which is what the word actually means), scholars loosely define myths as culturally-shared narratives that bind, inspire or help delineate a particular culture. In the academic world, the word myth “is detached from popular associations with falsehood.” They equate to “legends,” which may or may not be based on actual truths. Myths are often pre-scientific stories used to explain why things are as they are. They may represent “types” or models, or they might exaggerate a real event. They may conflate multiple events into a single story, and they typically make erroneous assumptions based on an incomplete understanding of actual facts.
Anciently, oral and written traditions were not “histories” in the modern sense. While such accounts were often based on actual events, historical accuracy was not a high priority. The main purpose was to share cultural events, heroes and villains intentionally selected to relate specific points. Tales of real events could be molded to help convey the moral of the story.
