Brother Rush. Friar Rush. Medieval German Folk Lore

The devil kills and cooks the cook in a monastery, taking over, disguising himself as a monk and causing calamity. My Friar Rush is carrying the cooks head on a platter under a room of fan vaults. At one point, I thought I'd like a stained glass window, but then I took it out. I want to keep a simple palette with that nice brown cloak.
