Af Upplendinga konunum is a short tale of the Norwegian part of the so-called Yngling.
Olof Trätälja lived in Varmland, and his wife was the sister of silver Sølve the old one from Solør.
Øystein married the daughter of Eirik Agnarsson king of Vestfold, but died when he fell overboard on his ship.
Øysteins son named Halfdan, and was called the gentle and food-stingy, because he gave his men a lot of gold, but starved them for food.
This covers an equally long period Yngling Saga, but is much easier and goes over scarce two sides.
[6] The version in Historia Norvegiæ is probably the oldest of the existing sources, while Yngling Saga is the youngest.
