Ágrip af Nóregskonungasǫgum: A Twelfth-Century Synoptic History of the Kings of Norway

Edited and Translated with an Introduction and Notes by J. M. Driscoll.
"Ágrip af Nóregskonungasǫgum" or "Ágrip" is a history of the kings of Norway. Written in Old Norse, it is along with "Historia Norvegiæ", one of the Norwegian synoptic histories. The preserved text starts with the death of Hálfdan svarti (c. 860) and ends with the accession of Ingi krókhryggr (1136) but the original is thought to have covered a longer period, probably up to the reign of Sverrir (1184–1202). The work was composed by an unknown Norwegian writer around 1190. The only surviving manuscript is Icelandic from the first half of the 13th century. The preserved parchment book consists of four quires, a fifth quire has been lost. The first leaf is also missing, therefore the original title of the book, if it had any, is unknown. The name "Ágrip af Nóregskonungasǫgum" ("A Synopsis of the Sagas of the Kings of Norway") was first used in an edition in 1835.
"Ágrip" is often compared with the two other Norwegian synoptic histories from the same period, "Historia Norvegiæ" and the work of Theodoricus monachus. It broke ground by being the first one written in the vernacular. "Ágrip" is also the first of the kings' sagas to quote skaldic poetry in the text. The narrative is brief, and much less detailed than the narratives of the later kings' sagas, such as "Fagrskinna" and "Heimskringla". The story is noticeably more detailed in descriptions of events and locations in the Trøndelag region and the city of Nidaros.
