The Gigantes Codex (Codex Giganteus), or "Devil's Bible", is an impressive medieval manuscript in the Latin language. The book weighs over 74 kilograms, is 92 centimeters long and 22 centimeters wide. It is the largest still extant among those written in the Middle Ages.
Includes 310 sheets of parchment taken from the skins of 160 donkeys (or calves).
This codex is kept in the Swedish capital, Stockholm, in the premises of the National Library, where it arrived in 1648 as a spoil of war from the Thirty Years' War. It was formerly in Prague, in the collection of Emperor Rudolph II, and said to have come from a Bohemian Benedictine monastery.
The Devil's Paw - The carefully written manuscript contains a 50 cm tall portrait of the Devil. And this fact gave birth to the legend of a sinful monk who was condemned to be walled alive if he did not atone for his sins, writing in one night a book that was supposed to contain all human knowledge. At midnight the desperate monk asked the Devil for help, giving him his soul in exchange.
What's behind the words - However, an examination of the text reveals something else. The writing of this book lasted for 20 years and was completed in the year 1229. This conclusion has been reached based on the latest reported facts. The book includes the Bible text, Cronica Bohemorum (1125) by Cosmas of Prague, an obituary calendar, magical formulas, and the Greek, Cyrillic, and Hebrew alphabets. The author is a monk, a certain Herman Inclusus, i.e. "the solitary one", in the sense of isolation from the world, and not "the living walled-in", as the legend says.
