Actually, there is evidence that medieval Satanism incorporated elements of pagan traditions such as Zoroastrian dualism, Gnosticism, Hermeticism, Greco-Roman witchcraft, and Diana worship. See history professor Donald Nugent's Masks of Satan for documentation from primary and secondary sources and a refutation of the "Christianity invented Satanism" thesis. Jeffrey Burton Russell's work is also a good resource.

With reference to the mention of Satanism being distinct from Wicca, Wicca was invented by Aleister Crowley's protege Gerald Gardner, who was an OTO initiate. It is the OTO's brand of Satanism rebranded to appeal to feminists who would not want to label themselves "Satanists," similar to the way the Communist Party created various fronts to appeal to people who would not want to join the CP.

PS: Donald Nugent = Christopher Nugent (Dr. Nugent has published under both names, I believe he used “Christopher” for that book).
