Laufey or Nál is a figure from Norse mythology and the mother of Loki. Eddic poetry refers to Loki by the matronym, Loki Laufeyjarson (Old Norse 'Loki Laufey's son'), rather than with a patronymic. She also is identified as the consort of Fárbauti.
Laufey is mentioned several times in the Prose Edda, composed in the thirteenth century by Snorri Sturluson. The first mention occurs in Gylfaginning, where High introduces Loki. High says that Loki is the son of Fárbauti, that "Laufey or Nál" is his mother, and that his brothers are Býleistr and Helblindi. Elsewhere in Gylfaginning, Loki is referred with employment of the matronymic, Laufeyjarson (Old Norse 'Laufey's son'). This occurs twice more in Gylfaginning and once in Skádskaparmál. In addition, poetic means of referring to Loki are provided in the Prose Edda book, Skaldskaparmal, including 'son of Fárbauti' or 'son of Laufey'.
Nál is mentioned twice in the Prose Edda, both times appearing in the phrase "Laufey or Nál"; once in Gylfaginning and once in Skáldskaparmál.
Nál means "needle"; according to Sörla þáttr. Laufey also was called this because she was "both slender and weak." The meaning of Laufey is less clear, but is generally taken to be "full of leaves"; as Fárbauti means "dangerous hitter", there is a possible nature mythological interpretation with lightning hitting the leaves, or needles of a tree to give rise to fire.
