Once upon a time there was a poor widow, who found an egg under a pile of brush as she was gathering kindlings in the forest. She took it and placed it under a goose, and when the goose had hatched it, a little boy slipped out of the shell. The widow had him baptized Knös, and such a lad was a rarity; for when no more than five years old he was grown, and taller than the tallest man. And he ate in proportion, for he would swallow a whole batch of bread at a single sitting, and at last the poor widow had to go to the commissioners for the relief of the poor in order to get food for him. But the town authorities said she must apprentice the boy at a trade, for he was big enough and strong enough to earn his own keep.
So Knös was apprenticed to a smith for three years. For his pay he asked a suit of clothes and a sword each year: a sword of five hundredweights the first year, one of ten hundredweights the second year, and one of fifteen hundredweights the third year. But after he had been in the smithy only a few days, the smith was glad to give him all three suits and all three swords at once; for he smashed all his iron and steel to bits.
Knös received his suits and swords, went to a knight's estate, and hired himself out as a serving-man. Once he was told to go to the forest to gather firewood with the rest of the men, but sat at the table eating long after the others had driven off and when he had at last satisfied his hunger and was ready to start, he saw the two young oxen he was to drive waiting for him. But he let them stand and went into the forest, seized the two largest trees growing there, tore them out by the roots, took one tree under each arm, and carried them back to the estate. And he got there long before the rest, for they had to chop down the trees, saw them up and load them on the carts.
On the following day Knös had to thresh. First he hunted up the largest stone he could find, and rolled it around on the grain, so that all the corn was loosened from the ears.
