The text is important, among other things, because it constitutes (in Latin translation) an independent version of Þjóðólfr of Hvinir's Ynglingatal besides the text in Ynglinga saga in the Heimskringla.
Heyerdahl's intention was to prove the veracity of the account of Snorri Sturluson in the Ynglinga saga, written in the 13th century, about the origin of the Norse royal dynasties, and the pre-Christian Norse gods.
Snorri Sturluson relates in his Ynglinga saga that the Swedish king Ingvar, Östen's son, was a great warrior who often spent time patrolling the shores of his kingdom fighting Danes and Estonian Vikings (Víkingr frá Esthland).
Gylfaginning in the Prose Edda and the Ynglinga saga tell how the supposedly historic (Non-deified version of Odin) Odin and his people the Æsir and Vanir, who later became the Swedes, obtained new land where they built the settlement of Old Sigtuna.
