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 now kept in the National Records of Scotland in Edinburgh. The manuscript contains several other texts; the Historia itself is in folios 1r-12r. Recent dating efforts place it somewhere c. 1500-1510A.The original text was written several centuries 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.
