Excalibur is the sword of King Arthur in Sir Thomas Malory's iconic work Le Morte D'Arthur published in in 1485 CE. The sword was originally introduced in Geoffrey of Monmouth's History of the Kings of Britain (1136 CE) as Caliburnus (or Caliburn) and further developed by later writers before Malory immortalized it in his work. The sword, from its first appearance, is a powerful weapon in the hands of a skilled warrior and retains that reputation in every story which features it.
