The primary sources regarding Asgard come from the Prose Edda, written in the 13th century by Icelandic Snorri Sturluson, and the Poetic Edda, compiled in the 13th century from a basis of much older Skaldic poetry.

In the 12th century eddic prose Gylfaginning Snorri Sturluson relates it as the first of a series of abodes in heaven:

The pair are attested in both the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda, written in the 13th century by Snorri Sturluson.

Both Fundinn Noregr and Snorri Sturluson in Skáldskaparmál state that Ægir is the same as the sea-giant Hlér, who lives on the isle of Hlésey, and this is borne out by kennings.

The dating of the events in the poem has been confirmed by archaeological excavations of the barrows indicated by Snorri Sturluson and by Swedish tradition as the graves of Ohthere ( dated to c. 530 ) and his son Eadgils ( dated to c. 575 ) in Uppland, Sweden.

Eadgils was buried at Uppsala, according to Snorri Sturluson.

The bridge is attested as Bilröst in the Poetic Edda ; compiled in the 13th century from earlier traditional sources, and as Bifröst in the Prose Edda ; written in the 13th century by Snorri Sturluson, and in the poetry of skalds.

The Prose Edda by Snorri Sturluson.

Snorri Sturluson quoted this old poem in Skáldskaparmál, saying that because of this legend Heimdall is called " Seeker of Freyja's Necklace " ( Skáldskaparmál, section 8 ) and Loki is called " Thief of Brísingamen " ( Skáldskaparmál, section 16 ).

Snorri Sturluson writes in the Gylfaginning after describing Odin, Thor, and Baldr:

Snorri Sturluson clearly distinguishes the god Bragi from the mortal skald Bragi Boddason whom he often mentions separately.

In the Prose Edda Snorri Sturluson quotes many stanzas attributed to Bragi Boddason the old ( Bragi Boddason inn gamli ), a court poet who served several Swedish kings, Ragnar Lodbrok, Östen Beli and Björn at Hauge who reigned in the first half of the 9th century.

The Icelandic mythographer and historian Snorri Sturluson referred to dwarves ( dvergar ) as " dark-elves " ( dökkálfar ) or " black-elves " ( svartálfar ).

" A third, proposed in 1895 by Eiríkr Magnússon, but since discredited, is that it derives from the Icelandic place name Oddi, site of the church and school where students, including Snorri Sturluson, were educated.

The derivation of the word " Edda " as the name of Snorri Sturluson ’ s treatise on poetry from the Latin " edo ", " I compose ( poetry )" by analogy with " kredda ", " superstition " from Latin " credo ", " creed " is now widely accepted.

It was written by the Icelandic scholar and historian Snorri Sturluson around 1220.

Fenrir is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources, and the Prose Edda and Heimskringla, written in the 13th century by Snorri Sturluson.

Freyja is attested in the Poetic Edda, compiled in the 13th century from earlier traditional sources ; in the Prose Edda and Heimskringla, both written by Snorri Sturluson in the 13th century ; in several Sagas of Icelanders ; in the short story Sörla þáttr ; in the poetry of skalds ; and into the modern age in Scandinavian folklore, as well as the name for Friday in many Germanic languages.

The problem is that in Old Norse mær means both " daughter " and " wife ," so it is not fully clear if Fjörgynn is Frigg's father or another name for her husband Odin, but Snorri Sturluson interprets the line as meaning Frigg is Fjörgynn's daughter ( Skáldskaparmál 27 ), and most modern translators of the Poetic Edda follow Snorri.

Frigg plays a major role in section 49 of the 13th century Prose Edda book Gylfaginning written by Snorri Sturluson, where a version of a story relating the death of Baldr is recorded by Snorri.

In the Ynglinga Saga of Snorri Sturluson the entire story is told as follows: " Othin had two brothers.

Later in the work, when Snorri describes Baldr, he gives a longer description, citing Grímnismál, though he does not name the poem:

In autumn, Gudrid gives birth to a son, Snorri.

Snorri then gives examples from skaldic verse where these names are used as general terms for ' lord ' or ' ruler '.

* c. 1007: Gudrid ( born in Iceland around 950 ) gives birth to a son, Snorri, the first European child born in North America.

The saga Heimskringla, written in Iceland in the thirteenth century by the poet and historian Snorri Sturluson, gives the ninth century Norwegian founder king Harald Fairhair three sons with Svanhild, including Ragnar Rykkel, Bjørn Farmann and Olaf Haraldsson Geirstadalf.

Other parts of the extensive work of Snorri Sturluson ( and other saga writers ) may however be considered valid references for finding elements of the ancient history of Scandinavian people and their religious customs and beliefs.

Snorri finishes his account by briefly mentioning that the Skjöldunga saga contained an extensive account of how Hrólfr came to Uppsala and sowed gold on the Fyrisvellir.

Snorri Sturluson gave an extensive account on the life of Ingjald in the Ynglinga saga which is part of the Heimskringla.

He searched for the remains of a civilization to match the account of Odin in Snorri Sturlusson, quite a bit north of his original target of Ajerbaijan on the Caspian Sea only two years earlier.

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.

The account is documented in the Skáldskaparmál, in the Prose Edda by Snorri Sturluson.

In chapter 4, Snorri presents a euhemerized account of the Æsir-Vanir War.

Scholars have debated as to what extent Snorri's account of Ymir is an attempt to synthesize a coherent narrative for the purpose of the Prose Edda and to what extent Snorri drew from traditional material outside of the corpus that he cites.

Snorri Sturluson cites this passage in his account of Ragnarök in the Gylfaginning section of his Prose Edda.

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 provides a euhemeristic account, in which he describes the Norse god Odin and some other Norse gods, the Æsir, as having been real people who emigrated from the area around the river Don to Scandinavia at the time of the Roman expansion into their old homeland.

In chapter 1 of the Heimskringla book Ynglinga saga, Snorri Sturluson refers to the two in an euhemerized account, stating that Freyja had a husband named Óðr, two daughters named Hnoss and Gersemi, and that they were so beautiful that their names were used for " our most precious possessions " ( both of their names literally mean " jewel ").

In Snorri Sturluson's Ynglinga saga, a part of the Heimskringla, he mentions the tradition of Halga, Eadgils and Yrsa, and he based his account on the Skjöldunga saga ( he had access to the now lost original version ).

The following description is based on the account in Ynglinga saga, written in the 1220s by Snorri Sturluson.

: Grammaticus ' account shares likeness, many characters and stories with the writings of Snorri Sturluson.

In the first account, Snorri cites a fragmentary poem called Kálfsvísa:
