By the time of the Ynglinga Saga, Snorri had developed his concept of Asgard further, although the differences might be accounted for by his sources.

" Snorri further writes that there Hel is located in Niflheim.

Saxo's inclusion of Amleth is the most significant part of the Gesta Danorum, however the work also has value in its description of the canonization of Canute and further in comparison to Snorri, whose work shares many characters and stories, creating a better understanding of pre-Christian Scandinavia.

Simek says that Snorri ’ s description is further proven faithful by way of the ( above mentioned ) 10th century skaldic kenning “ Kvasir ’ s blood ” ( Old Norse Kvasis dreya ), and that strong parallels exist between the Old Norse tale of the theft of the Mead of Poetry by Odin ( in the form of an eagle ) and the Sanskrit tale of the theft of Soma — beverage of the gods — by the god Indra ( or an eagle ), and that these parallels point to a common Proto-Indo-European basis.

Snorri writes further:

Arnkel became involved in further disputes with Snorri after Arnkel's father, Thorolf Halt-foot, accused Snorri of stealing his firewood.

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

In Skáldskaparmál Snorri writes:

All things did but a giantess by the name of Þökk, regarding whom Snorri writes that " people believe that the giantess was Loki.

Although he lists her own ancestors as unknown, Snorri writes that Thor and Sif produced a son by the name of Lóriði, who " took after his father ".

Snorri writes that Hel was cast down into Hel by Odin who " made her ruler over Nine Worlds.

In the Gylfaginning Snorri writes of Nótt:

In Scandinavia, Snorri writes, they so impressed the native population that they started worshipping them as gods.

Snorri writes that Odin settled in Lake Logrin, " at a place which formerly was called Sigtúnir.

" Further, Snorri writes that, after this, Njörðr dwelt in Nóatún, Freyr dwelt in Uppsala, Heimdall at Himinbjörg, Thor at Þrúðvangr, Baldr at Breiðablik and that to everyone Odin gave fine estates.

Snorri writes that the dark-elves are " black ", svart, but simultaneously he writes of all " black-elves " being dwarves.

One of the captives was a remarkably beautiful girl named Yrsa, and Snorri writes that everyone was soon impressed with the well-mannered, pretty and intelligent girl.

Snorri talks of the animosity between Eadgils and Onela ( which also appears in Beowulf ), and writes that Aðils ( Eadgils ) was at war with a Norwegian king named Áli ( Onela ).

Some manuscripts of the Skáldskaparmál give, along with other material, a list of the sons of Odin, which does not altogether fit with what Snorri writes elsewhere and so is usually thought to be a later addition.

In his preface to the Heimskringla ( which includes the Ynglinga saga ), Snorri writes:

While Gudrød is portrayed as a king in Oppland in some older texts, Snorri writes that he was a king in Vestfold.

Snorri Sturluson writes in Heimskringla and Fagrskinna, that King Harald Fairhair inherited part of Vingulmark from his father Halfdan the Black.

Snorri Sturluson writes in the Skáldskaparmál that two Sigars belong to the same clan, the Siklings, and that they are the relatives of Siggeir, the villainous Geatish king in the Völsunga saga.

Snorri Sturluson, the Icelandic historian, writes about the King in Berle, and his sons were a central subject in the histories of Harald Fairhair.

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.

Völuspá, the first poem of the work, mentions many of the features and characters of Asgard portrayed by Snorri, such as Yggdrasil and Iðavöllr.

Snorri proposes the location of Asgard as Troy, the center of the earth.

The sons of Bor then constructed Asgard ( to be identified with Troy, Snorri insists in section 9 ) as a home for the Æsir, who were divinities.

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

The first of these tells the mythological prehistory of the Norwegian royal dynasty, tracing Odin, described here as a mortal man, and his followers from the East, from Asaland and Asgard, its chief city, to their settlement in Scandinavia ( more precisely to east-central Sweden, according to Snorri ).

Snorri states in Gylfaginning that Glaðsheimr is a meeting hall, containing twelve high seats where the male Asgardians hold council, located in Iðavöllr in Asgard, near the hall of Vingólf where the Asgardian goddesses gathered.

In the 13th century Prose Edda, Snorri Sturluson relates that the Svartálfar Sindri, the brother of Brokkr, made Mjölnir while in a contest with Loki to see who could make the most wonderful and useful items for the Gods and Goddesses in Asgard.

Snorri quips: " There is a huge crowd there, and there will be many more still ...." ( Section 39 ).

In the initial stanzas of the poem Asagarth is the capital of Asaland, a section of Asia to the east of the Tana-kvísl or Vana-Kvísl river ( kvísl is " fork "), which Snorri explains is the Tanais, or Don River, flowing into the Black Sea.

It is unclear what people Snorri thinks the Vanes are, whether the proto-Slavic Venedi or the east Germanic Vandals, who had been in that region at that time for well over 1000 years.

Troy cannot have been Asagarth, Snorri realizes, the reason being that the Æsir in Asaland were unsettled by the military activities of the Romans ; that is, of the Byzantine Empire.

Snorri says at first it is Valhalla and then adds: " The Swedes now believed that he had gone to the old Asagarth and would live there forever " ( Section 9 ).

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 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.

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.

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 ).

The first part of Snorri Sturluson's Skáldskaparmál is a dialogue between Ægir and Bragi about the nature of poetry, particularly skaldic poetry.

" 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.

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.

In reference to Fenrir's presentation in the Prose Edda, Andy Orchard theorizes that " the hound ( or wolf )" Garmr, Sköll, and Hati Hróðvitnisson were originally simply all Fenrir, stating that " Snorri, characteristically, is careful to make distinctions, naming the wolves who devour the sun and moon as Sköll and Hati Hróðvitnisson respectively, and describing an encounter between Garm and Týr ( who, one would have thought, might like to get his hand on Fenrir ) at Ragnarök.

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.
