The Legend of Sigurd and Gudrn. Many years ago, J.R.R. Tolkien composed his own version of the great legend of Northern antiquity, recounted here in The Legend of Sigurd and Gudrún. The Lay of Gudrún recounts her fate after the death of Sigurd, her marriage against her will to the mighty Atli, ruler of the Huns (the Attila of history), his murder of her brothers, and her hideous revenge.
