Egyptian Mythology - Isis

My storytelling instructor gave me what I think is an excellent definition of mythology: "Other people's religion." That, my friend, is where mythology comes from.

What we today call Greek Mythology came from the ancient peoples of the Mediterranean.

Most other mythology comes to us from cultures who did not record their religion nearly so long or detailed a way.

Greek mythology simply deals with Greece and Persia (Crete too Possibly other countries when involved in myth). Other countries ancient history is not included in this GREEK mythology.
