As a humanities major, it strikes me as a perfectly plausible title for an overpriced 4000-level or Masters degree text in Medieval Studies. Probably also accompanied by three other similar sounding texts and a xeroxed (or PDF'd, these days) packet of random essays assembled by the professor 15 years ago.
It is probably one of those LLM-written books popping up everywhere. Once you have automated the process from LLM to ebook, you can produce them in masses for next to nothing, flood the markets, and hope that someone buys them and forgets to return them. Even if they find only 5-10 victims per book, it's nearly 100% profit.
