Note 59 — Chapter IV · THE MYTHOLOGY AND COSMOGONY OF THE NORSEMEN.
Reading edition
Jörmungand is the world serpent, Midgard’s serpent, the son of Loki.
“Angrboda was a Jötun woman in Jötunheimar. Loki begat three children by her: Fenrir wolf, Jörmungand, or Midgardsorm, the serpent, and Hel. When the gods knew that these three children were brought up in Jötunheimar, they had foretellings that great misfortune and loss would be caused by them, and all thought much evil must be expected from them, first on account of their mother, and still more of their father. Allfödr (Odin) sent the gods to take and bring them to him. When they came to him he threw the serpent (Midgardsorm) into the deep sea that lies round all lands, and it grew so much that it lies in the middle of the sea round all lands and bites its tail” (Later Edda, c. 34).
