The raven is a common iconic figure in Norse mythology.
Huginn (from Old Norse «thought») and Muninn (Old Norse «memory» or «mind») are a pair of ravens that fly all over the world, Midgard, and bring information to the god Odin. Huginn and Muninn are attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources.
Huginn and Muninn’s role as Odin’s messengers has been linked to shamanic practices, the Norse raven banner, general raven symbolism among the Germanic peoples, and the Norse concepts of the fylgja and the hamingja.
Odin was also closely linked to ravens because in Norse myths he received the fallen warriors at Valhalla, and ravens were linked with death and war due to their predilection for carrion. It is consequently likely that they were regarded as manifestations of the Valkyries, goddesses who chose the valiant dead for military service in Valhalla. A further connection between ravens and Valkyries was indicated in the shapeshifting abilities of goddesses and Valkyries, who could appear in the form of birds.
