Excalibur is the mythical sword of King Arthur that may possess magical powers or be associated with the rightful sovereignty of Britain. Traditionally, the sword in the stone is the proof of Arthur's lineage. The sword given to him by the Lady of the Lake is not the same weapon, even though in some versions of the legend both of them share the name of Excalibur. Several similar swords and other weapons also appear within Arthurian texts, as well as in other legends.
