On becoming a werewolf

Obviously, there are as many different ways to become a werewolf as there are werewolf stories. Every culture gives their own explanation of these transformations, running the gamut far from the single version expunged by Hollywood.

This page spells out one such transformation ritual. I have no idea where it comes from. The site appears to be somewhat researched, but no citations are used anywhere. It has a heavy bias toward European myths, and much of the ritual contains elements common in German, French, and English myths.

The rest of the site is a mix of semi-useful and useless information, though the major problem is how the author tries to over-simplify werewolf lore into a unified theory. The history of werewolfery offers such complex and often contradictory information, that to attempt to amalgamate it into a single explanation means picking and choosing which myths you think are "true." And that's just silly.
