Hrœrekr Ringslinger

Hrœrekr Ringslinger or Ringscatterer,Old Norse: Hrærekr slöngvanbaugi, Old Danish: Rørik Slængeborræ or Rørik Slyngebond was a legendary 7th-century king of Zealand or Denmark, who appears in Chronicon Lethrense, Annals of Lund, Gesta Danorum, Sögubrot, Njáls saga, Hversu Noregr byggðist, Skjöldunga saga, and Bjarkarímur.

Beside the name, the Danish and the West Norse traditions have little more in common than his living a few generations after Hrólfr Kraki, his name and his title. He may be most notable as the grandfather of Hamlet.

The name Slængeborræ, in Chronicon lethrense and the Annals of Lund is a corruption of Slænganbøghe, which is the Old East Norse form of Old West Norse slöngvanbaugi meaning "ring slinger", i.e. a king who was generous with his gold.Saxo's version Slyngebond means "bracelet slinger" and the motivation Saxo gives is strikingly different (see below).

In the Danish tradition Rørik is the son of an earthly Höðr, and notably the grandfather of Hamlet. Rørik is described as a powerful king of Denmark.

The Chronicon lethrense and the Annals of Lund make Rørik the son of an earthly Höðr who killed Balder, Odin's son in battle. Höðr was himself killed by Odin's son Both.
