King Olaf had been two summers and one winter in the west in Valland on
this cruise; and thirteen years had now passed since the fall of King
Olaf Trygvason. During this time earls had ruled over Norway; first
Hakon's sons Eirik and Svein, and afterwards Eirik's sons Hakon and
Svein. Hakon was a sister's son of King Canute, the son of Svein. During
this time there were two earls in Valland, William and Robert; their
father was Richard earl of Rouen. They ruled over Normandy. Their sister
was Queen Emma, whom the English king Ethelred had married; and their
sons were Edmund, Edward the Good, Edwy, and Edgar. Richard the earl of
Rouen was a son of Richard the son of William Long Spear, who was the
son of Rolf Ganger, the earl who first conquered Normandy; and he again
was a son of Ragnvald the Mighty, earl of More, as before related. From
Rolf Ganger are descended the earls of Rouen, who have long reckoned
themselves of kin to the chiefs in Norway, and hold them in such respect
that they always were the greatest friends of the Northmen; and every
Northman found a friendly country in Normandy, if he required it. To
Normandy King Olaf came in autumn (A.D. 1013), and remained all winter
(A.D. 1014) in the river Seine in good peace and quiet.
