The Devil’s Bible, also called the Codex Gigas, is the largest medieval manuscript in the world. It’s a sleep story about a 13th-century book said to have been written in a single night with the Devil’s help. Tonight we follow the Devil’s Bible from a snowbound Bohemian monastery to the court of Emperor Rudolf II in Prague, then onto a Swedish war wagon in the Thirty Years’ War, through the 1697 fire at Stockholm’s Tre Kronor castle, and finally to the National Library of Sweden, where it rests today. Weighing about 75 kilograms, written in a single hand, and holding a full-page portrait of the Devil, the Codex Gigas has inspired legends for eight hundred years. This story asks what a walled-up monk was really trying to keep inside it.
