In the past I've heard a lot of "Odinists" and "Wotanists" and "Odalists" and whatnot talk about the Christian conquest of Europe and about how all Pagan identity was to be wiped out by the new Christian doctrine, I don't really know if those people really look around to see our current society. Greece, now one of the first countries in Europe to be worried about being taken over by Islam, was also one of the first to be reached by Christianity in its infancy and ask any modern Greek: Do you know who Zeus is? Do you know Herakles? Poseidon? Olympos?
Yes, here is the thing. European paganism is everywhere. There is no sign of Christianity attempting to wipe it out. Our weekdays, they're still named after Freya (Friday) and Thor (Thursday) and Wotan (Wednesday), our months are still named after ancient Roman pagan gods like June (Juno - Jupiter) or January (Janus), they're not wiped out or eliminated or anything. Our holidays, they're apporpriations of pagan holidays, such as Jule, the festival of the winter solstice, turning into Christmas, or the celebration of the spring equinox turning into Easter. They're not being wiped out, they're not being erased from memory. That is not what the invasion of Christianity into Europe intended.
You see, it was not about wiping out and replacing with a foreign doctrine, it never was. It was, from the beginning, sold as as "update". It was like "these pagan folks, they're good-hearted, they're good people, they're pious, they just need their faith to be a bit better" - their version of better. Like they saw the paganism here, they saw how it fit their needs, and did not want to tell people they're all wrong, they wanted to tell people their faith was okay, it just needed to be improved a little with monotheism and the one God sacrificing his son to die for our sins. Like okay, you're pagan and all, and all your faith and all your beliefs and all your rituals are all fine, it's just that your gods are actually one God, and everything's actually okay because for all you've sinned, that one God sent his son to die for it. It wasn't meant to be a replacement, it wasn't meant to tell people their past faith has been all wrong, it was meant to be an "update", summarizing their gods into one, and uniting it all under the idea of the sacrifice of the holy son of God. We still got our Jule with the different name and our Thor's day.
But Christianity did do something with our ancient faith. Just like the ancient Norwegians had no word for evil, and Christianity used the word for "ghosts" (aander) to mean "evil" (onde), Christianity wanted to erase the pagan concept of evil by all means necessary as its ideology of "pure good" was to exclude all things "evil". The result of that ideology is that contrary to the popular neo-pagan belief that all history of ancient pagan "good" being erased, we do indeed have texts like the poetic and prose Edda, which were deliberately preserved by Christian agitators to perpetuate a world in which all is "good" and in which the pagan beliefs spoke only of a world that is "good" that merely required a wholesome update by Christianity to make sense in its "goodness". That on the other hand is also the reason why there is a complete lack of pagan texts on all that is the opposite of the Christian definition of "good".
Here is the lie and the conspiracy that we hit. A century ago, author Howard Phillips Lovecraft heavily referenced a work he called the "Necronomicon", which he referred to as being of Arabic origin with no linguistic proof to back up his claim, and in today's society this is widely claimed to be his own work. This is a false claim, just like the author's claim of the origin was. Modern research indicates that indeed, rather than being a fictional creation of Lovecraft himself, and rather than being of a foreign origin, the "Necronomicon" is a linguistically distorted preservation of ancient European pagan tales of evil that were banned from Europe by the invading Christian ideologues. Indeed, "Arabic" linguistic influences can be clearly demostrated to be added on to the text later on when retracing the origins of the names. This is only because when these writings were forcefully banned from Europe, their only copies would remain in areas far from Europe and the European and Christian sphere of influence. The original names were much closer to Indo-European linguistic characteristics. This can clearly be seen in the root syllables of many of the names referenced in the "Necronomicon", if one compensates for the Arabizations that are a logical consequence of the texts' banishment on the European continent.
The texts referred to as the "Necronomicon" therefore represent a hidden puzzle piece in the re-establishment of a full picture of European paganism, the "dark side" that the conquest of Christianity in Europe was seeking to erase, but that is no less important to the European pagan spirit as the poetic and prose Edda. The names may have been distorted by their Arabic translations and re-translations over the centuries to take them away from their Indo-European linguistic origins, but they remain no less important a part of the European pagan pantheon as Odin or Thor.
