Norse sources of the high medieval period, most prominently Snorri Sturluson's Heimskringla, also give a Polish princess as Cnut's mother, whom they call Gunhild and a daughter of Burislav, the king of Vindland.

According to Snorri Sturluson's Heimskringla, he was named Magnus ( Magnús in Old Norse ) by Sigvatr Þórðarson, his father's Icelandic skald, after Charlemagne, Carolus Magnus in Latin.

Traditionally, following Völuspá and Snorri Sturluson's account in the Prose Edda, scholarship on the Vanir has focused on the Æsir – Vanir War, its possible basis in a war between tribes, and whether the Vanir originated as the deities of a distinct people.

In Snorri Sturluson's Prose Edda, Baldr goes to Hel upon death and subsequently Hermóðr uses Sleipnir to attempt to retrieve him.

Along with Snorri Sturluson's Prose Edda, the Poetic Edda is the most important extant source on Norse mythology and Germanic heroic legends, and from the early 19th century onwards has had a powerful influence on later Scandinavian literatures, not merely through the stories it contains but through the visionary force and dramatic quality of many of the poems.

The Skáldskaparmál, in which Snorri relates the fight between Thor and Hrungnir, mentions a very different cause, and Þjóðólfr of Hvinir's Haustlöng only describes the fight without giving the reason for it.

Snorri quotes his own source saying: " The sun will go black, earth sink in the sea, heaven be stripped of its bright stars ;...." ( Section 56 ).

For events of mid-12th century, Snorri explicitly names the now lost work Hryggjarstykki as his source.

Snorri Sturluson gives an extensive account of Olaf in Heimskringla, ( c. 1230 ), using Oddr Snorrason's saga as his main source.

Słupecki argues that the Vanir remained distinct from the Æsir — except for Freyja and Freyr, whom he follows Snorri in seeing as having been born after Njörðr became a hostage among the Æsir, and thus regards as Æsic — and therefore that Ragnarök " no importance for their world ".
