Heimskringla; Or, The Chronicle of the Kings of Norway

'Heimskringla' is a collection of sagas about Swedish and Norwegian kings, beginning with the saga of the legendary Swedish dynasty of the Ynglings, followed by accounts of historical Norwegian rulers from Harald Fairhair of the 9th century up to the death of the pretender Eystein Meyla in 1177. It was written by Snorri Sturluson. Heimskringla consists of several sagas, often thought of as falling into three groups, giving the overall work the character of a triptych. The saga narrates the contests of the kings, the establishment of the kingdom of Norway, Norse expeditions to various European countries, ranging as far afield as Palestine in the saga of Sigurd the Crusader, where the Norwegian fleet is attacked by Arab Muslim pirates, referred to as Vikings.
