THOR´S HAMMER In Norse mythology Mjolnir (also commonly) spelled Mjollnir; literally, „that which crushes“ is the Hammer of Thor, the god of lightning and thunder. It is the most fearsome weapon in the arsenal of the Norse pantheon, used to slay any challengers to Æsir supremacy. Legend surrounding the war hammer´s origins vary: some relate that „The black Elves“, or dwarves, Sindri and Brokk made it at the behest of the calculating Loki; other tales contend that it descended to earth as a meteorite.
