The Vegvisir or runic compass is a Viking rune stave, a magical device used to aid in sea navigation. According to a number of legends, this apotropaic (protective) symbol was inscribed on seagoing vessels to insure their safe return. The most common depiction of the rune comes from the 17th century Galdrabók, and Icelandic grimoire.
Today, it is most commonly paired with the aegishjalmer, used as a symbol of spiritual guidance and an emblem of identification by Asatru believers. The most well-known example is worn as a tattoo by the Icelandic pop singer Bjork.
