Why do mythical and semi-mythical people pop up here?
There are several reasons for this. One is that many pedigrees have been created showing the descent of royalty from important people, including mythical gods and goddesses. Another is the tendency over time to amplify the accomplishments of a real historical person, producing a semi-mythical figure. Examples of this are Charlemagne, El Cid, and so on. Mythical people will inevitably be discussed here–mainly to help us understand where the myth ends and history begins, but also because myths tell us something about the people that believed in them.
