The Dwarves are one of races that inhabit Middle-earth in Tolkien’s universe. They play a central role in both The Hobbit and The Lord of the Rings. In the Poetic Edda, in Völuspá (Voluspa), the dwarves are created from the blood of Brimir and the limbs of Blain. Both names are other names for the giant Ymir, who was killed by the Aesir (a clan of Norse gods).
Snorri Sturluson tells the story in his Gylfaginning from the early 13th century of how, with Odin at the helm, the Aesir created the earth out of of the dead body of Ymir. Brimir’s blood became the sea and Blain’s limbs, the mountains (created by his bones).
All of the dwarves’ names are mentioned in the Poetic Edda. There are many similarities between the dwarf names mentioned in the Poetic Edda and in Tolkien’s works, including Durin, Bombur, Nori, Thorin and Egeskjold. Tolkien makes a big point of mentioning the dwarves by name when they are introduced in The Hobbit. And the myth of their origin and family relationships is also more complex in Tolkien’s universe than in medieval literature.
