Nott, in Norse mythology, a giantess, the personification of Night, and the mother of Dag (Day) and Jord (Earth). Her father, Narfi (or Norfi), was a giant who first settled Jotunheim, the realm of the giants. Nott was black and swarthy, like her father. She married Delling, a relative of the Aesir gods who was fair, and their son Dag favored his fathers side, and was bright. According to the 'Prose (or Younger) Edda', Delling was Nott's third husband. Her first husband was named Naglfar, and by him she had a son named Aud. Then she married Annar, by some accounts a dwarf, and had a daughter, Jord. The principal god, Odin, took Nott and her son Dag, gave them two horses and two chariots, and set them up in the sky so that they had to ride around the Earth every 24 hours. Nott rode in front. Her horse was called Hrimfaxi (Frost-maned), and every morning, from the drip of his bit, the dew formed on the Earth. Dag's horse was called Skinfaxi (Shining-maned), and his mane shed light over all the sky and sea.
