Harthacnut I of Denmark
Harthacnut I or Cnut I (Danish: Hardeknud; Old Norse: Hǫrða-Knútr) was a semi-legendary King of Denmark. The old Norse story 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.
