Mythology is the study of whatever religious or heroic legends are so foreign to a student's experience that he cannot believe them to be true. . . . Myth has two main functions. The first is to answer the sort of awkward questions that children ask, such as: 'Who made the world? How will it end? Who was the first man? Where do souls go after death?'. . . . The second function of myth is to justify an existing social system and account for traditional rites and customs.
