HUGIN and MUNIN, names given to Odin’s two ravens, who descend to earth, and bring back to him the news from the nether world; when not employed as messengers, they perch themselves on Odin’s shoulders. By Hugin is meant “thought,” and by Munin “memory.”

HVERGELMER, name of a source or fountain in Niffelheim. Etym.: Hver (urn or kettle), and gamla (old).

HYMIR, name of a giant, with whom Thor goes a-fishing in the disguise of a peasant lad. He catches the serpent Jormundgard, but Hymir files in two the anchor which served as a hook, and the serpent escapes.

IDA, IDAVALLEN, name of the plain, on which the resuscitated Asar and the human race are to be assembled by Vidar, after the reconstruction of the world.

IDUNA, name of an Asynia, wife of Bragur. She is the guardian of the golden vase, containing the apples of immortality, the juice of which gives to the gods perpetual youth, health and beauty. She was once carried off from Asagard by the giant Thiasse, aided by the treachery of Asa Lok; and the gods became at once old and feeble; but when Iduna was recovered, and brought back to Valhalla with her precious vase, the gods recovered all their power and advantageous attributes. This mythe of Iduna’s apples has its parallel in the Amreeta (drink of immortality) in the Hindoo mythology.

ISSEFIORD, name of a large creek or fiord, in the island of Sealand (Denmark), lying towards the north.

JETTE, pl. JETTER, JOTUN. So were called the evil genii or giants of the Gothic mythology. Historically, they were probably the aboriginal inhabitants of Scandinavia, and were of Celtic race, with black hair. Being engaged in continual and deadly warfare with the Asar or Goths, from the time of Odin’s invasion, these last may have, from a spirit of national hatred, transferred the appellation Jotun to the evil genii of their own mythology, before that epoch termed Hrimthusser. In spite, however, of the hatred and jealousy between the Asar and Jetter, they sometimes, like the Spaniards and Moors, formed political and also matrimonial alliances.

JORMUNGARD, name of the mythologic serpent, called also the serpent of Midgard. This serpent was offspring of Asa Lok, by the giantess Angurbod. His enormous size and frightful appearance excited such terror in the breast of the gods, that they hurled him down into the ocean that surrounds Midgard. There he is to remain until Ragnarok. On that day he will join the giants in the battle against the gods, and will be slain by Thor; but Thor will perish himself immediately after, from the effect of the serpent’s venom. This serpent is represented by the poets as holding his tail in his mouth, and is no doubt an emblem of the great Ocean, which was thought in those times to encircle the earth. His venom represents the dangerous effects of humidity. In the Hindoo mythology, there is the serpent Naga, which typifies the Ocean. Etym.: jord (earth), munr (mouth), gard (inclosure).

JOTUN (giant); see Jette and Giant.

JOTUNHEIM, peculiar province of the Jotun or giants in Utgard. Geographically, it is thought to denote Siberia.
