So what are the origins of the average fantasy wizards? As in them being mostly normal people who have the power to cast wide variety of spells?
I realize that the source is once again Tolkien if I had to guess, but he had to get the idea from somewhere, right? But from my knowledge of folklore, nothing akin to them really existed before Tolkien. You had more pagan folklore, but spells there were far more just mortals tampering with the spiritual / godly world (so more like fantasy priests or druids), or the creatures doing magic being godly themselves. Then with Christian folklore spells seem to be far more just very specific and usually evil enchantments, eg most of Brothers Grimm stuff, or just works of Satan. So what are the origins of the stereotypical DnD Mage, who has a wast access to diverse powers and little reliance on anything other than their own proficiency?
