Wicca as we and think of today is the most popular Neopagan religion, originally founded by the British civil servant Gerald Gardner, probably in the 1930s, although it was first openly revealed in 1951. Since its founding, various related Wiccan traditions have evolved, the original being Gardnerian Wicca, which is the name of the tradition that follows the specific beliefs and practices established by Gerald Gardner.

But there is another much older form known as Volva.
The Volva, vala, seidhkona, or wicce was a female shaman in Norse mythology, and among the Germanic peoples. They practiced the seid (shamanism), which was regarded as unmanly.
Examples of Volva in Norse literature include the seeress Heidi in Voluspa and the witch Groa in the Svipdagsmal. The word witch is the modern form of wicce.

Any to share/questions?

....that still tells me nothing of the beliefs and practices....

I think it's fascinating that such a new religion has so many followers and that many of them/us believe it's an ancient religion, which in my view it kinda is, it is mostly made of old pagan beliefs and stuff

and believing it's ancient also makes me feel a bit better in following it, otherwise I'd just feel like an idiot :D
