The
great sword Gram, the
Norse analog to
The Sword in the Stone.
Odin sunk it into the
Branstock tree in the
Saga of the Volsungs, and predicted the man who could pull it out would become mighty and do
great things. Sound familiar?
It was pulled out by the hero Sigmund, who at his death bequeathed it to his son Sigurd - you might know him as Siegfried - who used it to slay the dragon Fafnir.
Translates to "Angry" in the Old Norse.
Richard Wagner calls it "Notung" in the Ring Cycle operas.
