Huginn and Muninn
In Norse mythology, Huginn and Muninn (sometimes anglicized as Hugin and Munin; or ; roughly "mind and will" – see § Etymology) are a pair of ravens that serve under the god Odin, flying around the world (Midgard) and bringing him information. Huginn and Muninn are attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources: the Prose Edda and Heimskringla; in the Third Grammatical Treatise, compiled in the 13th century by Óláfr Þórðarson; and in the poetry of skalds.
