They gotta pay those medieval manuscript licensing fees

You can probably get coffee table book representations of some books. I have a Canterbury Tales and Mallory’s Le Mort d’Arthur. Not really medieval, but they’re done up as such.

Making a book even close to the style of medieval manuscripts is an incredible amount of hand printing and artwork. Some are absolutely beautiful, and a cost of tens of thousands is not unreasonable for a year or more of an artist’s effort.
