Ágrip af Nóregskonungasögum

Written in Old Norse, it is, along with the Historia Norvegiæ, one of the Norwegian synoptic histories.

[1] 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 name Ágrip af Nóregskonungasögum ("A Synopsis of the Sagas of the Kings of Norway") was first used in an edition in 1835.

[2] Ágrip is often compared with the two other Norwegian synoptic histories from the same period, Historia Norvegiae and the work of Theodoricus monachus.

The story is noticeably more detailed in descriptions of events and locations in the Trøndelag region and the city of Nidaros.
