 <p>Excalibur is the name for the legendary sword of King Arthur, in Welsh it is called Caledfwlch,
   in Cornish it is called Calesvol, in Breton it is called Kaledvoulc'h, and in Latin it is called Caliburnus.
   In some versions Excalibur's blade was engraved with phrases on opposite sides which in translation read:
   "Take me up" and "Cast me away" (or similar).</p>
