Mythology can be a little confusing.
It seems every book I pick up to read has different names and different stories for each god and goddess. I am finding myself more attracted to the Egyptian dieties considering I was born in Memphis, TN and know a little more about it. The other major difference between say the Celtic realm of mythology is that Egypt's year is opposite from ours, their seasons are reversed because they are so close to the equator. I have many links and books and myself am a member of the Fellowship of Isis. I can give you more links and info if you like.
