Certainly one of the if not the most important and famous of all the Norse Sagas is indeed the Völsunga Saga (Volsunga Saga or Volsungasaga). This is a saga that I feel everyone who is spiritually invested or are devoted to the beliefs of Norse Paganism should have included in their library. The tales in it are extremely fascinating, well written and truly paint visual image of such Gods as Odin and Loki as well as the deeds of man such as Sigurd the dragon Slayer. This saga is comprised of 44 stories and each just as good as the next.
Based on Viking Age poems and composed in thirteenth-century Iceland, The Saga of the Volsungs combines mythology, legend, and sheer human drama in telling of the heroic deeds of Sigurd the dragon slayer, who acquires runic knowledge from one of Odin’s Valkyries. Yet the saga is set in a very human world, incorporating oral memories of the fourth and fifth centuries, when Attila the Hun and other warriors fought on the northern frontiers of the Roman empire.
