Query: unreadable to all but a PHD Student of Gothic Architecture

I agree with the retired Professor who said it reads like a PHD dissertation. As a textbook for a bachelors level class it is useless. It assumes graduate level knowledge of very technical terms and does not offer translations for the many foreign language quotes. As a 4th year Art History major and prior holder of a BA in Anthropology, this is the worst textbook I've ever used.
