Ólafs saga Tryggvasonar

Óláfs saga Tryggvasonar is the name of several kings' sagas on the life of Óláfr Tryggvason, a 10th century Norwegian king.

Latin versions were written by Oddr Snorrason, and by Gunnlaugr Leifsson; both are now lost, but are thought to survive in Norse transcriptions including that recorded by Snorri Sturluson in Heimskringla; the most detailed version is Óláfs saga Tryggvasonar en mesta [The Greatest Saga of Óláfr Tryggvason], found in the Flateyjarbók, Bergsbók, and other manuscripts.
