Harthacnut I Of Denmark
Harthacnut or Cnut I (Danish: Hardeknud) (born c. 880) was a legendary King of Denmark. Adam of Bremen makes him son of an otherwise unknown king Sweyn, while the saga Ragnarssona þáttr makes him son of the semi-mythic viking chieftain Sigurd Snake-in-the-Eye, himself one of the sons of the legendary Ragnar Lodbrok.
