Story of the Heath-Slayings (Heitharviga)

Heiðarvíga saga or The Story of the Heath-Slayings is one of the Icelanders' sagas. It is badly preserved; 12 leaves of the only surviving manuscript were destroyed along with their only copy in the fire of Copenhagen in 1728. The content of that part is only known through a summary written from memory by Jón Grunnvíkingur who had made the lost copy.
The saga is written in a quaint and clumsy style, which some scholars have taken as indication that it is among the oldest Icelanders' sagas.
