You should take the position from the image and make a puzzle out of it.
Using medieval rules, of course. 🙂
This image is interesting for several reasons:
1. The board has light and dark squares. Though chess in one form or another was well known throughout Eurpoe by 1000, the use alternating regular pattern of light and dark squares didn’t really become common until 1100-1200.
2. The lack of perspective – interesting perspective from an artistic and geometric angle doesn’t appear in European art for a while longer – early renaissance – when artists would take advantage of the chessboards pattern to help create lines of convergence and vanishing points.
