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 is kept at Brechin Castle, Scotland. However, the manuscript itself is fragmented; the Historia itself is in folios 1r-12r. Recent dating efforts place it somewhere c. 1500-1510A.< The original text appears to have been written earlier than the manuscript itself; the text refers to both a volcanic eruption and an earthquake in 1211 as contemporary events, and Orkney is stated to be under Norwegian rule.
