Borr

Borr or Burr (Old Norse: 'son'; Sometimes anglicized Bor, Bör or Bur) was the son of Búri, the husband of Bestla, the father of Óðinn, Vili and Vé, and the grandfather of Thor, Baldr, Víðarr and Váli in Norse mythology.

Attestation
Borr is mentioned in the fourth verse of the Völuspá, a poem contained in the Poetic Edda, and in the sixth chapter of the Gylfaginning, part of Snorri Sturluson's Prose Edda.

Gylfaginning
Borr is not mentioned again in the Prose Edda. In skaldic and eddaic poetry Odin is occasionally referred to as Borr's son but no further information on Borr is given.

Theories and interpretations
The role of Borr in Norse mythology is unclear. Nineteenth-century German scholar Jacob Grimm proposed to equate Borr with Mannus as related in Tacitus' Germania on the basis of the similarity in their functions in Germanic theogeny.

The 19th century Icelandic scholar and archaeologist Finnur Magnússon hypothesized that Borr was "intended to signify [...] the first mountain or mountain-chain, which it was deemed by the forefathers of our race had emerged from the waters in the same region where the first land made its appearance. This mountain chain is probably the Caucasus, called by the Persians Borz (the genitive of the Old Norse Borr). Bör's wife, Belsta or Bestla, a daughter of the giant Bölthorn (spina calamitosa), is possibly the mass of ice formed on the alpine summits." In his Lexicon Mythologicum, published four years later, he modified his theory to claim that Borr symbolized the earth, and Bestla the ocean, which gave birth to Óðinn as the "world spirit" or "great soul of the earth" (spiritus mundi nostri; terrae magna anima, aëris et aurae numen), Vili or Hoenir as the "heavenly light" (lux, imprimis coelestis) and Vé or Lóðurr as "fire" (ignis, vel elementalis vel proprie sic dictus).
