Historia Norwegiæ is a short history of Norway written in Latin by an anonymous monk. The only extant manuscript is in the private possession of the Earl of Dalhousie, and kept at Brechin Castle, Scotland. However, it is fragmentary; the Historia itself is found in folios 1r-12r. The manuscript was once dated to the 15th century, but more recent dating efforts place it somewhere c. 1500-1510 (Kunin and Phelpstead 2001, x).
