The collection was also expanded through booty taken during the Thirty Years War. These captured treasures included the episcopal library of Würzburg in 1631, the University of Olomouc library in 1642, and the royal library of Prague in 1649. It was in this connection that the 13th-century “Devil's Bible” (the Codex Gigas) came to Stockholm. Queen Christina took much of this material with her to Rome after she abdicated the Swedish throne, but the royal collections continued to grow during the reign of Charles X Gustav through additional spoils of war and purchases abroad. The manuscript collection also includes the Anglo-Saxon Stockholm Codex Aureus.
