The sword of Joyeuse, which today sits in the Louvre Museum, is one of the most famous swords in history.  Historical records link the sword to Charlemagne the Great, King of the Franks. If it did indeed belong to the famous king, who reigned some 1,200 years ago, the sword of Joyeuse would have been used in countless coronation ceremonies, and is tied with ancient myth and legend ascribing it with magical powers.
