Lif and Lifthrasir (also spelled Life and Leifthrasir), in Norse mythology,
two people designated to be the sole human survivors after Ragnarok, the
battle at the end of the world. In the battle of Ragnarok, all the gods were
doomed to be destroyed, but the forces of evil would also be killed. The
woman Lif and the man Lifthrasir would survive the cataclysm, according to
the 'Prose (or Younger) Edda', by hiding in a place called Hoddmimir's Holt
(a small thicket of trees) while a great fire burned up the world. Their
only food would be the morning dew. After the gods and the monsters and giants
were all vanquished, Lif and Lifthrasir would worship the god Balder, son
of Odin, who would rise up from the dead after Ragnarok to rule in a new
heaven. Their progeny would repopulate the reborn Earth.
