RedReplicant photostream on Flickr: “God the Father fishing for Leviathan”, 12th Century: Herrad of Landsberg’s Hortus deliciarum: 19th C reproduction drawings. In the Public Domain.

This is a very unusual depiction of God the Father using Christ, who is strung on a line of Old Testament prophets who predicted the messiah, as the hook to ensnare Satan or “Leviathan.” Herrad was a nun and scholar whose book interpreted the history of the world. It is more than likely that she illustrated the book in addition to authoring it.
