In the Middle Ages fostering was practiced between the great families of Norway, possibly as a means of cementing interfamily alliances or demonstrating reciprocal status relationships. According to the Heimskringla, the chronicle of the Kings of Norway, written by Snorri St usson about 1225 (Harald Harfager's Saga, part 42): "it is a common observation of all people, that the man who fosters another's children is of less consideration than the other."[!] From the Heimskringla, which covers the years 850 to 1177, and other ancient sources, these are some of the fostered men and women:
(This list is based on the following six sagas: Ynglinga Saga, Halfdan the Black Saga, Harald Harfager's Saga, Saga of Magnus the Good, Magnus Barefoot's Saga, and Saga of Sigurd the Crusader and His Brothers Eystein and Olaf. There are another 10 individual sagas in the Heimskringla which I have not investigated.)
