Fagrskinna is one of the kings' sagas, written around 1220. It takes its name from one of the manuscripts in which it was preserved, Fagrskinna meaning 'Fair Leather', i.e., 'Fair Parchment'. Fagrskinna proper was destroyed by fire, but copies of it and another vellum have been preserved. An immediate source for the Heimskringla of Snorri Sturluson, Fagrskinna is a central text in the genre of kings' sagas. It contains a vernacular history of Norway from the ninth to the twelfth centuries, from the career of Halfdan the Black to the Battle of Re (1177), and includes extensive citation of skaldic verses, some of them preserved nowhere else. It has a heavy emphasis on battles, such as the Battle of Hjörungavágr and the Battle of Svolder. The book is often thought to have been written in Norway, either by an Icelander or a Norwegian.
