The Codex Gigas: The Devil's Bible
The largest medieval manuscript in existence contains a full-page portrait of the Devil and was allegedly written in a single night by a monk who made a deal with Satan.
In the National Library of Sweden sits the largest surviving medieval manuscript in the world: the Codex Gigas, or “Giant Book.” Standing nearly three feet tall and weighing 165 pounds, this 13th-century manuscript contains something unique among religious texts - a massive, full-page portrait of the Devil. Legend says a doomed monk wrote the entire book in a single night, with Satan’s help, to save his life.
The Manuscript
Physical Description
The Codex Gigas is extraordinary. It measures 36 inches in height, 20 inches in width, and 9 inches in thickness, totaling a weight of 165 pounds (75 kg). The manuscript consists of 310 leaves, yielding 620 pages. The text was meticulously inscribed on vellum, produced from the skins of 160 donkeys. Due to its size, it typically requires two people to lift it and occupies nearly three feet of shelf space.
Contents
The manuscript includes the complete Latin Bible (Vulgate translation), Josephus’s Antiquities of the Jews, Isidore of Seville’s Etymologies, a collection of medical texts and treatments, numerous magical formulas and incantations, historical chronicles of Bohemia, a calendar of saints, and confessional formulas. Notably, twelve pages were removed from the manuscript at some point, and the contents of these missing pages remain unknown. Most famously, it contains a full-page illustration of the Devil.
The Legend
The Doomed Monk
According to tradition, the manuscript was created at the Benedictine monastery of Podlažice in Bohemia (now Czech Republic) around 1204.
The story goes that a monk broke his monastic vows – the specific transgression varies by telling – and was subsequently sentenced to death by immurement, or being walled up alive. He begged for a chance to redeem himself, and promised to create a book that would glorify the monastery forever. He was given one night to complete the work.
The Pact with Satan
Facing an impossible task, the monk realized he could not complete the work alone. He then called upon Satan for help, and the Devil agreed to write the book in exchange for the monk’s soul. The book was completed by morning, and the monk added the Devil’s portrait as a tribute.
Some versions of the legend say the Virgin Mary saved the monk’s soul afterward, while others claim Satan collected his due.
The Devil’s Portrait
The Image
Page 577 contains a full-page illustration unlike anything in medieval religious art: Satan is depicted in vivid green with red horns, he has a lolling red tongue, and his hands and feet end in talons. He crouches in a squatting position, with his arms raised almost in greeting. The image takes up nearly the entire page.
Placement and Purpose
Opposite the Devil’s portrait is a full-page image of the Heavenly City – perhaps representing the choice between good and evil, damnation and salvation. No other medieval Bible contains such a prominent demonic image. Its inclusion has never been satisfactorily explained.
The Blackened Pages
The pages surrounding the Devil’s portrait are noticeably darker than the rest of the manuscript. Some suggest this darkening is the result of supernatural influence emanating from the image’s evil. Scientific analysis indicates natural aging and handling, and the pages were likely displayed open more frequently, but the legend persists.
Scientific Analysis
The Single Scribe Theory
Modern analysis suggests that the entire manuscript was written by one person. Handwriting analysis shows a consistent style throughout, indicating that it would have taken 25-30 years of continuous work. The “one night” legend is therefore physically impossible.
The Writing Conditions
Researchers have determined that the writing is remarkably consistent, with no evidence of haste or fatigue. The scribe maintained a high level of quality over decades, suggesting monastic discipline rather than demonic aid.
The Missing Pages
Twelve pages have been removed from the manuscript. The original content is unknown; they may have included monastery rules, additional illustrations, or something the church found objectionable.
History
The Monastery Period (1204-1594)
The manuscript remained in Bohemian monasteries: it was created at Podlažice, moved to the Břevnov Monastery, and later acquired by Prague’s Benedictine monastery.
The Swedish Acquisition (1648)
During the Thirty Years’ War, Swedish forces looted Prague in 1648, and the Codex Gigas was taken as war plunder. It entered Queen Christina’s library and has remained in Sweden since.
Modern Era
Today, the manuscript resides in the National Library of Sweden, is rarely displayed physically due to conservation concerns, has been digitized and made available online, and remains one of the world’s most unusual books.
Paranormal Associations
Cursed Book Claims
Some believe the manuscript is cursed. The monastery of Podlažice was destroyed after creating it, and misfortune is said to follow its owners. The book survived a fire that destroyed much of Stockholm’s royal library in 1697, thrown from a window to save it.
Ritual Use
The book contains medieval magical formulas, exorcism texts, and conjuration methods. Whether these were used or were merely included for reference is unknown.
The Monk’s Fate
If the legend has any truth, did the monk receive something beyond normal ability? Did he believe he was inspired by dark forces? Is there a psychological element to the demonic imagery?
Significance
Literary/Historical
The Codex Gigas represents medieval encyclopedic ambition, monastic devotion (if one man truly wrote it), 13th-century knowledge compilation, and a unique approach to religious art.
Paranormal/Legendary
The Devil’s Bible offers a tangible “cursed object” with documented history, a compelling origin legend, genuine mystery about its creation and purpose, and an image that defies medieval norms.
Psychological
The manuscript raises questions: why did a religious scribe create such a prominent demonic image? What drove someone to devote decades to a single book? Did the creator believe in the legend, or create it?
Visiting Today
The Codex Gigas is housed in the National Library of Sweden, is rarely displayed physically, can be viewed digitally online, and remains Sweden’s most unusual national treasure.
Legacy
The Devil’s Bible has inspired documentaries and books, novels and horror stories, ongoing historical research, and continued supernatural speculation. An 800-year-old book, written possibly by one man over decades, contains a full-page portrait of Satan and a legend of damnation. Whether the story is true, symbolic, or purely fictional, the Codex Gigas stands as the world’s largest medieval manuscript – and its most mysterious. The Devil inside continues to stare from those ancient pages, his meaning as obscure as the day he was drawn. And somewhere, perhaps, a monk’s soul still pays the price for his impossible book.
