Really enjoyed this episode, maybe even more than the story. I think you covered all the good and bad about it, so I won't say too much. I agree that it's kind of weird and doesn't make much sense, but that it's also an excellent example of Smith's abilities as a wordsmith. I know I've been a bit down on CAS in the past, but I feel like the Averoigne stories might just be what turn me round on him.
Anyway, the main reason I wanted to post is because, like Glenn getting the Omen soundtrack on shuffle before recording the episode, I've also had a weird coincidence when listening to the episode. I don't normally listen to two podcasts in one day, but today, right before listening to this episode I listened to another podcast episode on medieval and early modern magic that goes into more detail about some of the things you touched on, especially the link between Christianity and magic and the idea of acceptable vs unacceptable magic. It's here for anyone who's interested, and it also has a short reading list for people who want to delve even further: https://anchor.fm/thenaturepod/episodes/Magic-e14mmbq
Also, since Glenn wanted to know if Iron Maiden have any songs set in medieval southern France: yes, they absolutely do. It's about the last stand of the Cathars, so it fits very well with the story and what you were saying about how it would have been better if CAS had tied it to the rise of the Inquisition: https://www.youtube.com/watch?v=UaYyJhLB4Qw And for my money, one of the best Iron Maiden songs about magic is their song about John Dee (since you mentioned him too): https://www.youtube.com/watch?v=YH8nCYZSlIc
