Gyrd and Gnupa  Gyrd and Gnupa were kings of Denmark in the 10th century according to Sweyn II of Denmark and Adam of Bremen. They were the sons of the Swedish chieftain Olof (or Olaf) the Brash who had conquered Denmark and they ruled together according to Swedish tradition. Gnupa is mentioned on the two Sigtrygg Runestones raised near Schleswig by his wife Asfrid for their son Sigtrygg. Likewise a Danish king "Chnuba" is named by Widukind of Corvey's Saxon chronicles as having been defeated and forced to accept baptism in 934, and Olav Tryggvasson's Saga tells of Gnupa's defeat by Gorm the Old. However, this chronology would contradict that of Adam of Bremen, who places the succession and subsequent defeat of Sigtrygg during the tenure of Archbishop Hoger of Bremen (909–915/7). The late and legend-influenced Gesta Danorum of Saxo Grammaticus names a nobleman "Ennignup" serving as guardian for a young king Knut at some time prior to king Gorm the Old and it has been suggested he may be a confused representation of Gnupa.
