We don’t know—and we have no way to find out.
In the 1980s, I practiced Wicca. Wicca is the original, pre-Christian, goddess-centered nature religion of Europe. Despite centuries of persecution and the burning of millions of Wiccans as “witches,” it survived underground to modern times. When the British Witchcraft Act was finally repealed in 1951,1 courageous Wiccans began, cautiously, to practice their religion in public.
Well… that’s all hogwash, of course. It was obvious to skeptical Wiccans in the 1980s that our religion was an invented tradition, devised sometime in the twentieth century. It has only the vaguest of connections with pre-Christian European paganism. What we didn’t know, and had no way to find out, is whodunnit, and how, where, why, or quite when. Wicca’s inventors justified the religion as “ancient wisdom,” and they covered their tracks thoroughly. Their fabricated history was accepted uncritically by the vast majority of Wiccans. The inventors of other Neopaganisms adapted the Wiccan “unbroken secret tradition” mythology to their own systems. But as far as we skeptics were concerned, Wicca was a wonderful religion, regardless of where it came from.
The Triumph of the Moon: A History of Modern Pagan Witchcraft, published in 1999, was a breakthrough. Ronald Hutton, a serious non-Pagan historian, made key discoveries about Wicca’s twentieth century invention, and found suggestive evidence for broader hypotheses. His treatment was sympathetic and respectful—but facts are facts.
Not surprisingly, Hutton’s work was vitriolically rejected by many practicing Neopagans. Somehow, ancientness is proof of rightness for many people. I seem to lack the brain circuits for this. I can see no reason a 75-year-old religion is, on that account, any less valid than a millennia-old one. (Was Buddhism bogus when the Buddha taught it?) On the other hand, understanding how a religion was invented, and successively re-invented, helps understand how it functions now. Some aspects of Wicca that made sense in the 1940s make no sense now.
Despite Hutton’s discoveries, and further historical research, there is much that is still not known about how Wicca came about. Some key questions probably can never be answered.
