Historia Norwegiæ is a short Latin history of Norway written by an anonymous monk. The only extant manuscript, in the private possession of the Earl of Dalhousie and kept at Brechin Castle, Scotland, is fragmentary; what we have of the Historia is found on folios 1r-12r. The manuscript was once dated to the fifteenth century, but seems now to be from c.1500x1510 (Kunin and Phelpstead 2001, x). The text itself appears to have been created rather earlier, because it refers to a volcanic eruption and earthquake of 1211 as being contemporary, and Orkney is reported to be under Norwegian rule.
