Regular readers of this Blog may recall that we sometimes throw caution to the wind, and test their imagination with one of our fiendish caption competitions. Today is no exception. Here is an image from the famous Queen Mary Psalter (Royal MS 2 B VII, f. 81r): but what exactly is going on?

There are no prizes, but we'd like you to send us your wittiest captions, using the comment form at the bottom of this post or contacting us on Twitter via @BLMedieval. We'll publish and retweet the best responses: good luck!
