赤毛のエイリークのサガ
The "Saga of Erik the Red" contains an unusual amount of pagan practise, sorcery, and ghost stories. It has been used as a source on Old Norse religion and belief, in particular on the practice of prophecy as described in the scene with Thorbjorg, but is often described as unreliable. One scholar has described it as "a polemical attack on the pagan practices still supposedly prevalent around the year 1000 in Greenland".
