OK, so it kind of looks like a kick-ass Medieval version of Where The Wild Things Are. But it isn’t. This is The Devils’ Bible, or The Codex Gigas. This 13th century manuscript is the life’s work of a Benedictine monk named Herman the Recluse, who was pretty undeniably a bit touched in the head. With a name like Herman the Recluse, that’s hardly a surprise. The work contains most of the Bible, but interspersed with other things- medical texts, works by other authors, local historical records- oh, and following this depiction of the devil, magical formulas. The book has all kinds of a bizarre past- you can learn about it in this National Geographic Special– but here is the great part. Because the book now resides in the National Library of Sweden in Stockholm, it has been scanned and photographed in its entirety and is available to flip through yourself at the World Digital Library.
