The Chronicle of The Kings of Norway
Part 47 - Olaf The Tree-feller's Death
There were a great many people who fled the country from Sweden, on account of King Ivar; and when they heard that King Olaf had got good lands in Vermeland, so great a number came there to him that the land could not support them. Then there came dear times and famine, which they ascribed to their king; as the Swedes used always to reckon good or bad crops for or against their kings.
The Swedes took it amiss that Olaf was sparing in his sacrifices, and believed the dear times must proceed from this cause. The Swedes therefore gathered together troops, made an expedition against King Olaf, surrounded his house and burnt him in it, giving him to Odin as a sacrifice for good crops. This happened at the Venner lake.
Thus tells Thjodolf of it: —
"The temple wolf, by the lake shores,
The corpse of Olaf now devours.
The clearer of the forests died
At Odin's shrine by the lake side.
The glowing flames stripped to the skin
The royal robes from the Swedes' king.
Thus Olaf, famed in days of yore,
Vanished from earth at Venner's shore."
