What, then, is folklore? We might reply with such a dictionary definition as "Material that has been handed on by tradition." It is, in other words, the lore of the folk and not the learning in books. We have not come very far. Let us ask, then: What material? We might answer: Things, words, music, ideas (that is, customs and beliefs).
