In both sources, Sleipnir is Odin's steed, is the child of Loki and Svaðilfari, is described as the best of all horses, and is sometimes ridden to the location of Hel.
In modern times, Sleipnir appears in Icelandic folklore as the creator of Ásbyrgi, in works of art, literature, software, and in the names of ships.
In the Poetic Edda, Sleipnir appears or is mentioned in the poems Grímnismál, Sigrdrífumál, Baldrs draumar, and Hyndluljóð.
[3] In Sigrdrífumál, the valkyrie Sigrdrífa tells the hero Sigurðr that runes should be cut "on Sleipnir's teeth and on the sledge's strap-bands.
Gangleri (described earlier in the book as King Gylfi in disguise) asks High who the horse Sleipnir belongs to and what there is to tell about it.
After some debate, the gods agree to this, but place a number of restrictions on the builder, including that he must complete the work within three seasons with the help of no man.
The stallion Svaðilfari performs twice the deeds of strength as the builder and hauls enormous rocks to the surprise of the gods.
[9] The gods declare that Loki would deserve a horrible death if he could not find a scheme that would cause the builder to forfeit his payment, and threatened to attack him.
Hermóðr agrees to ride to Hel to offer a ransom for Baldr's return, and so "then Odin's horse Sleipnir was fetched and led forward."
"[12] In chapter 17, a story is provided in which Odin rides Sleipnir into the land of Jötunheimr and arrives at the residence of the jötunn Hrungnir.
Hrungnir asks "what sort of person this was" wearing a golden helmet, "riding sky and sea," and says that the stranger "has a marvellously good horse."
[18] In book I, the young Hadingus encounters "a certain man of great age who had lost an eye" who allies him with Liserus.
"[19] In book II, Biarco mentions Odin and Sleipnir: "If I may look on the awful husband of Frigg, howsoever he be covered in his white shield, and guide his tall steed, he shall in no way go safe out of Leire; it is lawful to lay low in war the war-waging god.
[21] The mid-7th century Eggja stone bearing the Odinic name haras (Old Norse 'army god') may be interpreted as depicting Sleipnir.
Lindow adds that the eight legs of Sleipnir "have been interpreted as an indication of great speed or as being connected in some unclear way with cult activity.
As an example, Davidson cites a funeral dirge from the Gondi people in India as recorded by Verrier Elwin, stating that "it contains references to Bagri Maro, the horse with eight legs, and it is clear from the song that it is the dead man's bier."
The encyclopedia states that "[...] Sleipnir is born with an extra set of legs, thus representing an original pair of horses.
[29][27] A statue of Sleipnir (1998) stands in Wednesbury, England, a town which takes its name from the Anglo-Saxon version of Odin, Wōden.
