wiccan witchery is a 1880 invention of some upperclass brits.
when charlemagne came to germany and defeated the saxon tribes which lived under a constitution that knew no king until then (only a 'herzog' in times of war, name derivates from the fact that it was the person riding in front of the army), charlemagne destroyed the nature religion that had until then been practised there. that was 777 AD. so were not talking about wiccan pop witches here.
