The only myths and legends most people know about are what they see in movies. For instance, the dragon was recorded all around the world, and they all agreed on all the details: feathered body of a serpent, bearded face of a lion, and eyes that shoot lightning bolts. Mesoamericans worshiped Quetzalcoatl for thousands of years, and the Chinese dance with a paper dragon to this day. But I bet you have only heard of the scaled beast with wings, and no agreement on the general shape or appearance.
