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.

In Gylfaginning, Snorri presents the mythological version taken no doubt from his sources.

According to Gylfaginning, a book of Snorri Sturluson's Prose Edda, Baldr's wife is Nanna and their son is Forseti.

In Gylfaginning, Snorri relates that Baldr had the greatest ship ever built, named Hringhorni, and that there is no place more beautiful than his hall, Breidablik.

It is briefly described in Snorri Sturluson's Gylfaginning as one of the halls of Asgard:

" ( Snorri, Gylfaginning 17, Prose Edda )

Gylfaginning, or the Tricking of Gylfi ( c. 20, 000 words ), is the first part of Snorri Sturluson's Prose Edda after Prologue.

" Davidson posits that Snorri may have " earlier turned the goddess of death into an allegorical figure, just as he made Hel, the underworld of shades, a place ' where wicked men go ,' like the Christian Hell ( Gylfaginning 3 ).

In the Gylfaginning part of Snorri Sturluson's Prose Edda Höðr is introduced in an ominous way.

According to the Ragnarök prophecies in Snorri Sturluson's Gylfaginning, the first part of his Prose Edda, the sons of Muspell will break the Bifröst bridge, signaling the end of times:

In Gylfaginning by Snorri Sturluson, Gylfi, the king of ancient Scandinavia, receives an education in Norse mythology from Odin in the guise of three men.

Rudolf Simek says that the etymology that Snorri presents in Gylfaginning for the name Gná may not be correct, yet it is unclear what the name may otherwise mean, though Gná has also been etymologically theorized as a " goddess of fullness.

In the Prose Edda, written in the 13th century by Snorri Sturluson, valkyries are first mentioned in chapter 36 of the book Gylfaginning, where the enthroned figure of High informs Gangleri ( King Gylfi in disguise ) of the activities of the valkyries and mentions a few goddesses.

Finally there is a short piece of prose summarizing the tale of Loki's binding, which is told in fuller form in the Gylfaginning section of Snorri Sturluson's Prose Edda.

In the Prose Edda, Snorri Sturluson gave this information in Gylfaginning but in a list of kennings in Skáldskaparmál equates Gymir with the god and giant Ægir, citing a verse by Hofgarða-Refr Gestsson where the kenning in question probably simply substitutes one giant-name for another.

In Gylfaginning, Snorri mentions the high seat on four occasions.

According to the Gylfaginning part of Snorri Sturluson's Prose Edda, Níðhöggr is a being which gnaws one of the three roots of Yggdrasill.

How Freyr killed Beli is told by Snorri Sturluson in Gylfaginning during the recounting of the wooing of Gerðr.

She is attested in Gylfaginning, a part of Snorri Sturluson's Prose Edda, in association with Ginnungagap and Ymir.

In Norse mythology, Nepr ( anglicized as Nep ) is the father of the goddess Nanna, according to Snorri Sturluson's Gylfaginning only.
