I am absolutely delighted by this cat throwing rocks at mice https://www.bl.uk/catalogues/illuminatedmanuscripts/ILLUMIN.ASP?Size=mid&IllID=2...
And later it appears the mice have taken the castle from the cat (who appears dead) and a cat with a bow as shown up to attack. https://www.bl.uk/catalogues/illuminatedmanuscripts/ILLUMIN.ASP?Size=mid&IllID=2...
I'm a big fan of these cross-page battles and the grotesques in the margins.
These are all from a Book of Hours. I'm loving it.
