Medieval air guitar

Every so often I show you an entertaining medieval doodle. Here is one I encountered in a French image database today. This tiny drawing on the blank last page of the book shows a figure passionately engaged in what can only be called playing air guitar. He is wearing his best silly hat and he is giving us his blankest look. It a weird image, put their by a scribe to test out his pen: an essential deed that left an amusing drawing.
