John Brantley just sent me a note in connection with my treatment of glamour:
“I have also seen glamour used as type of magic spell, particularly one that affect the perception of appearance. For example, “Marcie cast a glamour on herself to enhance her beauty.” or “Marcie uses cosmetics as a glamour to enhance her beauty.” Admittedly, this meaning is mostly limited to Fantasy literature, but it is reasonably widely used there. It also clearly fits in with the word history that you describe.”
I’m not surprised that it would still be used in the world of magic. That is the world in which the two meanings parted company for most speakers of English. However, I was unaware that the usage persists even there and though you all might be interested.
