Weird synchroncity, I literally was just last night watching an episode of Crash Course History specifically about witch-related trials and burnings, and this book was touched upon quite a bit!
It definitely seems to have been a major influence on the various 'traditional' ideas of witches and/or witchcraft as seen from the common, European Christian point-of-view. The book was basically a 'best seller' for its time, right after the Bible. It's pretty crazy how much influence and sway a collection of what are basically fairy tales had over this time period (and over a large geographic area, as similar cultural trends were taking place in the Americas at the same time).
