"Codex Gigas, also known as the Devil's Bible - a medieval manuscript said to have been written 800 years ago with the devil's help - has returned to Prague after an absence of 359 years. "According to a myth, a Benedictine monk promise to write the book overnight to atone for his sins. When he realised the task was impossible, he asked the devil for help. Only 60 people an hour can enter an air-conditioned room in the a National Library fo a 10-minutes look at the manuscript, which is inside a specially designed, unbreakable case." Has anyone ever heard of this Bible?
