11. "How doth All-father regulate the course of the sun and moon?"
asked Gangler.
"There was formerly a man," replied Har, "named Mundilfari, who had
two children so lovely and graceful that he called the male, Mani
(moon), and the female, Sol (sun), who espoused the man named Glenur.
But the gods being incensed at Mundilfari's presumption, took his
children and placed them in the heavens, and let Sol drive the horses
that draw the car of the sun, which the gods had made to give light to
the world out of the sparks that flew from Muspellheim. These horses
are called Arvak and Alsvid, and under their withers the gods placed
two skins filled with air to cool and refresh them, or, according to
some ancient traditions, a refrigerant substance called
_isarnkul_.[129] Mani was set to guide the moon in his course, and
regulate his increasing and waning aspect. One day he carried off from
the earth two children, named Bil and Hjuki, as they were returning
from the spring called Byrgir, carrying between them the bucket called
Saegr, on the pole Simul. Vidfinn was the father of these children,
who always follow Mani (the moon), as we may easily observe even from
the earth."
