What location is common to Knýtlinga saga and Cnut the Great?
Knýtlinga saga Knýtlinga saga ("The Saga of Cnut's Descendants") is an Icelandic kings' saga written in the 1250s, which deals with the kings who ruled Denmark since the early 10th century.
Harthacnut I of Denmark Harthacnut or Cnut I (Danish: Hardeknud ) (born c. 880) was a semi-legendary King of Denmark. "Ragnarssona þáttr" makes Harthacnut son of the semi-mythic viking chieftain Sigurd Snake-in-the-Eye, himself one of the sons of the legendary Ragnar Lodbrok. The saga in turn makes Harthacnut the father of the historical king, Gorm. It has been suggested he is to be identified with the Hardegon of "Northmannia" whose early-10th century conquest of Denmark was related by Adam of Bremen.
