He seems to have been an exile altogether some two years,--such is one's vague notion; for there is no chronology in Snorro or his Sagas, and one is reduced to guessing and inferring.

He had reigned over Norway, reckoning from the first days of his landing there to those last of his leaving it across the Dovrefjeld, about fifteen years, ten of them shiningly victorious.
The news from Norway were naturally agitating to King Olaf and, in the fluctuation of events there, his purposes and prospects varied much.
He sometimes thought of pilgriming to Jerusalem, and a henceforth exclusively religious life; but for most part his pious thoughts themselves gravitated towards Norway, and a stroke for his old place and task there, which he steadily considered to have been committed to him by God.

Norway, by the rumors, was evidently not at rest.

Jarl Hakon, under the high patronage of his uncle, had lasted there but a little while.

I know not that his government was especially unpopular, nor whether he himself much remembered his broken oath.
