Who gave arthur the sword excaliber?

Arthur received the sWord Excalibur from the Lady of the Lake, a mystical figure in Arthurian legend. In some versions of the tale, he first pulls the sWord from a stone, proving his right to the throne, but Excalibur, which symbolizes his rightful sovereignty and power, is given to him later by the Lady. This moment emphasizes the magical and divine right of kings in Arthur's story.
