Who was the father of the person Þórðr Kolbeinsson was the court poet for?
Þórðr Kolbeinsson Þórðr Kolbeinsson ("Thordr Kolbeinsson") was an 11th-century Icelandic skald, or poet. He was the court poet of Eiríkr Hákonarson and some 17 stanzas of his poetry on the earl are preserved in the kings' sagas. The following example is from Eiríkr's campaign in England with Canute the Great.
Rögnvald Brusason Rognvald was taken by his father to Norway, to the court of Olaf Haraldsson, when Brusi and Thorfinn went there to have the inheritance of Einar Wry-mouth's third-share of the Earldom settled. Olaf kept Einar's share for himself, appointing Brusi to administer it, and kept Rognvald at his court.
