Norse mythology contains references to various named weapons wielded by specific characters. The oldest references sometimes offer nothing except a name for the weapon, but some of them include more detail on the weapon and what makes it unique, such as Thor's famous hammer Mjölnir. These weapons have often been expanded upon in later cultural adaptations that involve Norse mythology. For example, Richard Wagner's Ring cycle of operas adds that Wotan (Odin)'s spear Gungnir is inscribed with all the agreements and treaties which Wotan has made with various other beings, and is the record and source of his power.
