Mythology is a very ancient, but at the same time a very vital form of creative fantasy. It is a dominant feature in the spiritual culture of primitive societies, and to some extent of ancient societies; it is the principal means of giving an overall sense to the world. In a primitive culture, mythology gives body to an as yet weakly differentiated syncretic unity of unconscious creation, primitive religion and the embryonic forms of pre-scientific notions about the surrounding world. Mythology provides the soil and the raw material for early forms of religion and of poetry.
