The Codex Gigas, the Latin for ‘Giant Book’ is an eight century old leather-bound manuscript that is thought to have been influenced by Satan.
The huge 89 centimetre tall, 49 centimetre wide book weighs 75 kilograms and is currently on display at the National Library of Sweden.
Across its hundreds of pages include a complete version of the Vulgate Bible – the Catholic Church’s official Latin Bible – and many texts pertaining to the teaching of medicines and magic.
But what has caught most people’s eye is the large, full page, colour drawing of the Devil on 577.
The origin of the Codex Gigas is unknown, but according to stories which have been past through generations, it was written by a doomed Benedictine monk in a Bohemian monastery.
It is believed the monk was sentenced to death after he broke his vows.
In a bid to escape his fate, he told authorities that if he could write an entire book in one night that contained all human knowledge as well as praising the monastery, then he should be let off.
Upon starting his task however, he realised that it would not be able to be completed in one night.
In desperation, the monk allegedly turned to the Devil for help.
According to the National Library of Sweden: “The Evil aided him, had his portrait painted in the book and asked the monk’s soul in return.
“The monk was saved but no peace, he was never seen again. He turned finally to the Holy Virgin and the prayer of salvation.
“Virgo handed him his helping hand, but the penitent died just at the moment when he would have been resolved by its contract with the devil.”
Tests carried out on the ancient bible have revealed that the entire book was indeed written by one person as the handwriting is consistent throughout.
According to a report in the Line Up, it would have taken five years of non-stop writing to complete.
The report adds: “Clearly, the author of this massive tome was possessed by something to create such a masterwork. Whether it was the power of light or darkness, is lost to time.”
