What is a Myth?
Before defining the term "mythology" one needs to define the meaning of the word "myth".

Furthermore, all myths are, at some stage, actually believed to be true by the peoples of the societies that used or originated the myth. The definition is thus clearly distinguished from the use of the word myth in everyday speech which basically refers to any unreal or imaginary story.
A myth is also distinctly different from an allegory or parable which is a story deliberately made up to illustrate some moral point but which has never been assumed to be true by anyone.
Some myths describe some actual historical event, but have been embellished and refashioned by various story tellers over time so that it is impossible to tell what really happened. In this last aspect myths have a legendary and historical nature.

For example one can group them geographically and then speak of "Oceanic Mythology", "Oriental Mythology" and "African Mythology".
A second meaning of the term mythology is the academic study of myths and systems of myths in general.
