(2 syl.). The famous smith of Scandinavian fable. He and Amilias had a contest of skill in their handicraft. Wieland's sword cleft his rival down to the thighs; but so sharp was the sword, that Amilias was not aware of the cut till he attempted to stir, when he divided into two pieces. This sword was named Balmung.
