Scholars have cited parallels between the Æsir–Vanir War, The Rape of the Sabine Women from Roman mythology, and the Mahabharata from Hindu mythology, providing support for a Proto-Indo-European "war of the functions."
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.
Proceeding to discuss the role of the Vanir in Norse mythology, he deals with Ingvi-Freyr of Uppsala in Sweden and then Ingui of Bernicia in Northern England, ultimately concluding that in early Anglo-Saxon history, a deity named Ingui was believed to be the progenitor of Anglian kings.
