The legendary Excalibur was actually two different swords
In short: We often imagine a single, magical blade, but Arthurian tradition is far more fractured. Depending on which medieval text you read, the King was either proving his lineage by pulling a sword from an anvil or receiving a mystical weapon from a Lady of the Lake.
The concept of Excalibur is a tapestry of evolving legends rather than a single, static myth. In Robert de Boron’s 1200 poem *Merlin*, the 'sword in the stone' motif is introduced, where Arthur proves his divine right by extracting a blade from an anvil atop a stone. However, the Post-Vulgate Cycle introduces a separate tradition: a sword gifted to Arthur by the Lady of the Lake. Thomas Malory, in his 15th-century *Le Morte d'Arthur*, famously conflated these two distinct weapons, giving them both the name Excalibur.
The sword's name itself has undergone a linguistic metamorphosis. It likely originates from the Welsh *Caledfwlch*, a compound of 'hard' and 'breach'. When Geoffrey of Monmouth wrote his *Historia Regum Britanniae* around 1136, he Latinised the name to *Caliburnus*. Over centuries of continental adaptation, various spellings emerged—including *Caliborne*, *Escalibor*, and *Excalibor*—before settling into the modern English Excalibur. Some even suggest a connection to the Irish sword *Caladbolg*, though scholars like Rachel Bromwich argue they may simply be generic ancient names for powerful blades.
Beyond the blade, the legends include a powerful scabbard that prevented the wearer from bleeding to be wounded to death. This protection was lost when Morgan le Fay stole it and threw it into a lake. The sword's history is also marked by extreme violence; in some accounts, Arthur's early attempt to use the stone-drawn sword resulted in it breaking during a duel with King Pellinore, necessitating the acquisition of the second, lake-given blade.
