Beaumanoir quickly pivots, as the book itself so often does, to blaming Jewish victims for the wrongs they suffer. The Witch of Endor appears in the Hebrew Bible as a figure who tries to use black magic to undermine the will of God. By invoking her in this moment, Aymer means to suggest stereotypes found throughout medieval Christian theology that suggest women are inherently devilish and dangerous. But the Grand Master takes the title literally, thanks to his belief that all medicine that Jewish people practice involves black magic.
