The precise time of composition of the saga also remains unknown, but the late 13th century seems most likely. The oldest extant manuscript uses vellum from the first half of the 15th century, but unfortunately only one page remains. Paper copies made from the complete manuscript preserve the full text of the saga. The partially extant skin manuscript may well have copied the original composition directly. In any case the saga seems faithful to the original, with little rewriting and few accidental errors.
