The manuscript vault of the early XIII century appeared in the Benedictine monastery. In history this book was mentioned by various names such as the Codex Gigas, or the Book of the Devil.
The height of 310 parchment sheets is 89 centimeters, width 49. According to scientists, all this work was done by one person, who had spent at least 20 or even 30 years.
The weight of the book is some 75 kg, which makes it difficult for a single person to move it. Several religious treatises have already been collected inside, from the full text of the Old Testament to the "Czech chronicle" of Kozma of Prague.
The book got its name because in its middle there is a full-page image of Satan. It is followed by a guide to exorcism — who knows what the author wanted, creating such a controversial work.
