A scriptorium was the place where medieval manuscripts were copied and illustrated.
The Digital Scriptorium is a digital library of manuscripts from over thirty-four
institutions. It is designed for scholars, but has a browsing feature that enables novices
to look up documents and see the intricate details of the illustrations and even the ink
smudges from a careless hand. Well worth a look.
Clicking on a topic brings up art images, with descriptions and period. Includes books, armor, castles and any other item that you can think of. Has some sponsor type ads, but the information is well worth ignoring these.
