Early Renaissance Drawings of Demons

Though it would be nobler to take the trouble to write and think through some sort of commentary, not much has come to mind so I will just post three pieces of this series of very strange drawings as standalone curiosities. I came across them a few weeks ago in connection with the Ashmolean Museum. I will say that the demons look remarkably un-frightening — more comical.
