On May 7, 1697, Stockholm's medieval royal castle was destroyed by fire, and the Codex Gigas, the world's largest existing medieval illuminated manuscript, survived by being thrown out a window. The book has a strange, legendary history. A short excerpt from the article:
"In 1697, a massive fire broke out at the royal castle, spreading quickly into both the east and west wings. The fire eventually reached the library and the librarian, Johann Jacob Jaches, directed the attempts to salvage the treasure within. Initially, books were carried out in piles, an operation that had to be abandoned as the stairwells filled with smoke. Desperate, castle staff began to throw books from the windows. Many were damaged in the rescue attempt, but at least saved in some form. Three-quarters of the estimated 24,500 printed works and 1,100 of the 1,400 manuscripts were lost to the flames.
The Codex Gigas was one of the books thrown from a window, severely injuring a man below in the process according to the later account of Johann Erichsons, vicar of the German Church in Stockholm. The fall of the book damaged the binding and caused several leaves to fall loose. They were never recovered."
