The Codex Gigas (Giant Book), also known as the Devil’s Bible, is the largest extant medieval manuscript in the world. According to the Codex legend, the single scribe was a monk who breached his monastic code and was sentenced to be walled up alive with no chance of escape. There was only one way the monk could avoid his excruciating death, he promised to create a beautiful, and fascinating book to glorify the monastery forever; a book that would include all human knowledge. There was one catch, he was given only twenty-four hours to complete the task in and if the monk would complete the task, then be free to live.
