Cerridwen

[Demophon]

She is often worshiped as a goddess by contemporary pagans, but as far as I know, she was a sorceress in Welsh mythology rather than a divine figure. I wonder what is it about her that makes her appeal to modern pagans.

In Marion Zimmer Bradley's The Mists of Avalon, Cerridwen is the name given to the Goddess worshiped by the priestesses of Avalon, so that influence of that book might have something to do with it. As a figure associated with sorcery and magic, I can see why witches in particular are drawn to her.

Is anyone aware of evidence for her as a goddess, and what is it that draws people to worship her as a deity?
