Snorri's account of Olaf Kyrre corresponds with the statements found in
"Agrip", "Fagrskinna", and "Morkinskinna".
There are but few events in Olaf's long reign, and hence he is very
appropriately called the Quiet (Kyrre). As Hildebrand says, this saga
seems to be written simply to fill out the empty space between Harald
Hardrade and Magnus Barefoot.
Skalds quoted in this saga are: Stein Herdison and Stuf.
