Illustration of a Devil found in the 13th century medieval manuscript Codex-Gigas. According to legend the book was written by a monk who sold his soul to the devil so in order to complete the manuscript in one night, and so complete the task which would let him off his execution (by being walled in alive) for breaking his monastic vows.
The Codex Gigas (Giant Book) is the largest medieval manuscript in the world. It is also known as the Devil’s Bible because of a large illustration of the devil on the inside and the legend surrounding its creation. It is thought to have been created in the early 13th century in the Benedictine monastery of Podlažice in Bohemia (modern Czech Republic). (The side is 22cm thick.)
