Nereus (nē´rūs).—Son of Pontus and Gæa, and husband of Doris, father of the fifty Nereids. He dwelt at the bottom of the sea, and was regarded as the wise old man of the sea. Like other marine divinities, he was supposed to have the power of prophesying the future, and of appearing to mortals in various shapes. The Ægean Sea was his empire—possibly the whole of the Mediterranean.
Nessus (ness´us).—A Centaur who was slain with a poisoned arrow by [Hercules] (q.v.).
Nestor (nes´tor).—Son of Neleus and king of Pylos. He was famous among the heroes before Troy for his wisdom, justice and eloquence. In early life he was a distinguished warrior, and took part in the fight between the Centaurs and the Lapithæ, and was one of the Calydonian hunters and one of the Argonauts. He is said to have lived through three generations of men. He safely reached Pylos again after the fall of Troy.
Nicneven.—A gigantic and malignant female spirit of the old popular Scottish mythology. The hag is represented as riding at the head of witches and fairies at Hallowe’en.

Niflheim.—Mist-home of old Norse mythology. The region of endless cold and everlasting night, ruled over by Hela. It consists of nine worlds, to which are consigned those who die of disease or old age. This region existed “from the beginning” in the north, and in the middle thereof was the well Hvergelmir, from which flowed twelve rivers.
Niobe (nī´o-bē).—Daughter of Tantalus and wife of Amphion, king of Thebes. Having seven sons and seven daughters, she imprudently boasted of her superiority to Latona, who had but two children—Apollo and Diana. The latter, indignant at her presumption, slew all her children with their arrows. Niobe herself was changed into a stone.
Niord.—The Scandinavian sea-god. He was not one of the Æsir. Niord’s son was Frey (the fairy of the clouds), and his daughter was Freyja. His home was Noatun. Niord was not a sea-god like Neptune, but the spirit of water and air. The Scandinavian Neptune was Ægir, whose wife was Skadi. His temples were near the seashore and all aquatic plants belonged to him.
Nisus (nī´sus).—A friend of Euryalus (ū-rī´a-lus).—The two accompanied Æneas to Italy, and perished in a night attack on the Rutulian camp.
