Njord (also spelled Njorth, Niord, or Njordr), in Norse mythology, a deity associated with wealth and good fortune who ruled over the sea and the course of the winds, and thus navigation. Sailors called on him to give them safe voyages and bountiful fishing. The Norse believed that Njord was so wealthy that he could grant great riches, in lands and possessions, to those who prayed to him. As he was associated with water and humidity, he also had the power to put out unwanted fires.
Njord was the father of the handsome god Frey, who was also associated with wealth, and the beautiful fertility goddess Freya. Although he was counted among the Aesir gods whose chief was the warrior Odin, Njord was originally one of the Vanir gods associated with agricultural societies. He went to live among the Aesir, in their heavenly realm of Asgard, as part of a peace settlement between the two warring groups. He brought Frey and Freya with him.
Scholars believe that Njord was the masculinization of an earlier female fertility goddess named Nerthus (Mother Earth), and this may account for the story that Njord's first wife was his own sister (Nerthus), by whom he had his children Frey and Freya.
In Asgard, Njord lived in a great palace called Noatun (which means "enclosure of ships"), and by a strange circumstance became the husband of a giantess named Skadi. Skadi had come to Asgard to avenge the death of her father, Thiassi, who had been killed by the gods after kidnapping the goddess Idunn. As reparation for her father's death, the gods offered to let Skadi marry one of them. But she was not allowed to see them--she had to choose by viewing only the gods' feet. One god's feet were exceptionally beautiful, and she chose him, assuming it was the handsome Balder, but in fact those feet belonged to Njord.
It was not an auspicious way to begin a marriage, and indeed, the two were not entirely compatible. According to the 'Prose (or Younger) Edda', Njord loved his seaside home, but Skadi preferred her father's domain, Thrymheim, in the mountains of Jotunheim (Giantland). So they initially agreed that they would alternate residences, staying nine nights in Thrymheim and then nine at Noatun. When Njord returned to Noatun from his first trip to Thrymheim, however, he said that he hated the mountains, with the sound of wolves howling, and preferred his swans by the sea. Skadi did not enjoy staying at Noatun, either, because, she said, the screaming of the seagulls kept her awake. So after a while Skadi returned to the mountains to live, where she enjoyed traveling on skis and shooting game with a bow and arrow. Njord thereafter remained in the palace he loved by the sea, where he could rule all things related to the mariner. "Njord's glove" was a poetic Norse term for a sponge.
