Dont get me started on Wicca, Animus. A manufactured creed at best, dating from the 1950's but with a core of the Craft. After all, Gardner called it New Witchcraft.
"good pool of knowledge of pre-christian faiths" - so agree with that which is why I stick to the meticulously researched books coming out of British academia [ Hutton, Davies, Wilby, etc].
I will admit that I have no interest in the pagan world outside of the British Isles, although the Cunning Folk were known across Northern Europe because of the common roots on the dry North Sea plain.
Anyway, an excellent area to discuss - so many unknowns in it
