Norðri, Suðri, Austri, Vestri
Four dwarves named for the cardinal directions; Snorri says the gods set one under each corner of the sky, which is made from Ymir's skull.
Norðri, Suðri, Austri and Vestri — North, South, East and West — are four dwarves who hold up the sky.
In Völuspá they are only names, early in the long list of dwarves: "Nyi and Nithi, Northri and Suthri, / Austri and Vestri, Althjof, Dvalin" Völuspá 11. The poem gives them no role.
Snorri does. When the sons of Borr have made the earth from Ymir's body, they take his skull and set it over the earth as the sky, "with four corners; and under each corner they set a dwarf: the names of these are East, West, North, and South" Gylfaginning 8. Brodeur translates the names, so in the hosted Gylfaginning they appear in English. The idea was established in poetry: Snorri lists "Burden of the Dwarves" and "Helm of Vestri and Austri, Sudri, or Nordri" as kennings for the sky, and quotes a skaldic verse in which "the Toil of Austri" bursts at the world's end Skáldskaparmál 23.
The sources do not say whether Snorri's sky-bearers were the first to have these names or whether he gave the job to four names he found in Völuspá. Scholars have compared them with other world-pillar and sky-bearer figures, but such comparisons are interpretation.
