Attention wiccans

Depends, are looking for modern or original? I can link you to the modern roots of it. However, the original roots aren’t so easy to find. There’s a book(only limited copies, I don’t believe there’s anymore than 10, 4 if I recall correctly) that will speak of a tribe call Hu Wika(spelling it how it sounds here). An ancient philosopher recorded information about them in his journals. They were slaughtered when they stood their ground against the Romans, when the Romans were driving the Celtics northward. They did practice sacrifice, unlike modern wicca, and I’ld assume had practices rooted in Celtic practices.

Modern Wicca, well, to me it's nothing more than a child's game so it would seem. A lot of feminist mar the original belief of a Goddess AND a God(you ned both male and female aspects to create life, and for true balnce, so it was believed) with just the worship of  Goddess(Dainic). Within the past 50 years of it's "resurfacing"(I believe Gerald Gardener just brought about a new religion under an ancient name really) there have been dozens of new traditions of Wiccan made up-such as Gardener("original"), Alexandrian, Dainic, Circles, Seax, "British Tradition" and even Fairie, "Egyptian". Really, the only thing the modern Wiccan and ancient share the possible celebrations of Celtic festivals. Even the gods and goddesses are marred with ancient Roman and Greek, however some still worship the Celtic gods. There's no longer any fine lines s to what is wicca and what isn't.
Many Wiccans(note, I didn't say all, or even half) claim it to be the very first religion when it was no where near even the third. Pantheism was the first known religion, wicca being one of the off shoots.
I've split my knowledge with you, you can take it or leave it.
