In Norse mythology, Gram (Old Norse Gramr, meaning "Wrath"),[1] also known as Balmung or Nothung, is the sword that Sigurd used to kill the dragon Fafnir.[2] It is primarily used by the Völsungs in the Volsunga Saga. However, it is also seen in other legends, such as the Thidrekssaga in which it is wielded by Hildebrand.
Depending on the story and source material, Gram may have other names. In The Nibelungenlied it is named Balmung.[3] In Richard Wagner's work, Der Ring des Nibelungen (The Ring of the Nibelung), it is referred to as Nothung ([ˈnoːtʊŋ], "child of need.")[4]
