Damien Kempf on Tumblr writes about this image from a 12th century manuscript known as the Bible of Stephen Harding. This work contains many images, including this page that details the story of King David. Just like a modern day comic book, you are supposed to go through this page from left to write and top to bottom, and read the caption for each box.
The manuscript - Dijon BM MS.14 - has been scanned and is available on the French government website www.enluminures.culture.fr
