克努特大帝
Óttarr svarti ("Óttarr the Black") was an 11th-century Icelandic skald. He was the court poet first of Óláfr skautkonungr of Sweden, then of Óláfr Haraldsson of Norway, the Swedish king Anund Jacob and finally of Cnut the Great of Denmark and England. His poems are significant contemporary evidence for the careers of Óláfr Haraldsson and Cnut the Great.
