Geoffrey in monmouth's Biography of Kings of Britain said that this sword was cast in Avalon, and the local language Caledfwlch was latinized into Caliburnus. Later, his works spread to the European continent and became Excalibur. Other works in the poems and chronicles of King Arthur in the Middle Ages include: Calabrion, Calabrium, Caliben, Caliber, Caliber, Esqali and Esqali. These stories also influenced the Latin Bible cultural circle famous for its Holy Grail culture. At first, these legends also included Merlin's poems, but the writers in the post-Latin Bible circle removed Merlin's part and added their own sources of Arthur's early life and Excalibur. Specifically, in the Biography of Merlin in the Latin Bible circle, it was clearly stated that the sword drawn from the stone was an Excalibur, but in later versions, it became a sword obtained from the fairy in the lake. Death of King Arthur wrote these two books, and the result was two swords. So Excalibur is a sword in the stone. Some people think that "sword in stone" is an allusion to metallurgy.
The sword in the stone, King Arthur chose the king's sword. Some people say that this is the prototype of Excalibur, Calibourne. The History of the Kings of England records that Calibourne said that King Arthur used this sword to kill 470 Saxon soldiers who attacked him in World War I.
The Legend of the King is a magical swordsman who appeared in the legend of King Arthur. It can be called the origin of the famous sword tradition in later knight literature.
According to the legend of King Arthur, King Arthur, who pulled out the sword in the stone and became king, broke the sword in the stone in a confrontation with King Pelino (personally, Sir Pelino). The cause of this battle was that when King Arthur visited a castle, the owner of the castle, Anulei, saw Sir Perinaud coming to the castle and asked King Arthur for protection. In fact, Sir Perinaud was teased by Anuel and came against King Arthur. This battle is considered a violation of chivalry, which is also the reason why the sword in the stone was broken. Later, under the guidance of Merlin, he got the legend of the king from the goddess in the lake. The Legend of the King was built in Avalon, an elf country. The blade of the sword is made of gold, and the hilt is inlaid with precious stones. Because its sharp blade cuts iron like mud, the lady in the lake is named Excalibur (meaning "broken steel" in ancient Celtic). Merlin warned Arthur at this time: "Although The Legend of the King is very powerful, its scabbard is more valuable than its sword. The legendary man who wears the scabbard of the king will never bleed. You must never lose it. 」
But later, King Arthur lost his scabbard, so although he had a sword as sharp as mud, he was finally killed by the traitor knight Mordred. The Legend of the King was finally thrown back into the lake by Sir Bedivere at the behest of King Arthur, and returned to the elf country of Avalon with King Arthur.
