There was a man called Dag, who is said to have been a son of King
Hring, who fled the country from King Olaf. This Hring, it is said
further, had been a son of Dag, and grandson of Hring, Harald Harfager's
son. Thus was Dag King Olaf's relative. Both Hring the father, and Dag
the son, had settled themselves in Svithjod, and got land to rule over.
In spring, when Olaf came from the East to Svithjod, he sent a message
to his relation Dag, that he should join him in this expedition with
all the force he could collect; and if they gained the country of Norway
again, Dag should have no smaller part of the kingdom under him than
his forefathers had enjoyed. When this message came to Dag it suited his
inclination well, for he had a great desire to go to Norway and get
the dominion his family had ruled over. He was not slow, therefore, to
reply, and promised to come. Dag was a quick-speaking, quick-resolving
man, mixing himself up in everything; eager, but of little
understanding. He collected a force of almost 1200 men, with which he
joined King Olaf.
