Some authorities declare that, instead of making part of the creative trilogy (Odin, Hoenir, and Lodur or Loki), this god originally belonged to a pre-Odinic race of deities, and was the son of the great giant Fornjotnr (Ymir), his brothers being Kari (air) and Hler (water), and his sister Ran, the terrible goddess of the sea. Other mythologists, however, make him the son of the giant Farbauti, who has been identified with Bergelmir, the sole survivor of the deluge, and of Laufeia (leafy isle) or Nal (vessel), his mother, thus stating that his connection with Odin was only that of the Northern oath of good-fellowship.
Loki (fire) first married Glut (glow), who bore him two daughters, Eisa (embers) and Einmyria (ashes); it is therefore very evident that Norsemen considered him emblematic of the hearth-fire, and when the flaming wood crackles on the hearth the goodwives in the North are still wont to say that Loki is beating his children. Besides this wife, Loki is also said to have wedded the giantess Angur-boda (the anguish-boding), who dwelt in Jötun-heim, and who, as we have already seen, bore him the three monsters: Hel, goddess of death, the Midgard snake Iörmungandr, and the grim wolf Fenris.
“Loki begat the wolf
With Angur-boda.”
Sæmund’s Edda (Thorpe’s tr.).
Sigyn
Loki’s third marriage was with Sigyn, who proved a most loving and devoted wife, and bore him two sons, Narve and Vali, the latter a namesake of the god who avenged Balder. Sigyn was always faithful to her husband, and did not forsake him even after he had definitely been cast out of Asgard and confined in the bowels of the earth.
As Loki was the embodiment of evil in the minds of the Northern races, they entertained nothing but fear of him, built no temples to his honour, offered no sacrifices to him, and designated the most noxious weeds by his name. The quivering, overheated atmosphere of summer was supposed to betoken his presence, for the people were then wont to remark that Loki was sowing his wild oats, and when the sun appeared to be drawing water they said Loki was drinking.
The story of Loki is so inextricably woven with that of the other gods that most of the myths relating to him have already been told, and there remain but two episodes of his life to relate, one showing his better side before he had degenerated into the arch deceiver, and the other illustrating how he finally induced the gods to defile their peace-steads by wilful murder.
