Then Gangleri said, ‘How does he steer the course of the sun and the moon?’
High said: ‘There was a man named Mundilfari who had two children. They were so fair and beautiful that he called one Moon [Mani] and the other, a daughter, he called Sun [Sol], marrying her to the man named Glen. But the gods were angered by this arrogance, and they took the brother and sister and placed them up in the heavens. There they made Sun drive the horses that drew the chariot of the sun, which the gods, in order to illuminate the worlds, had created from burning embers flying from Muspellsheim. The horses are called Arvak and Alsvinn. In order to cool them, the gods placed two bellows under their shoulders; according to some lore, the bellows are called Isarnkol. Mani guides the path of the moon and controls its waxing and waning. He took from the earth two children named Bil and Hjuki. They had been walking from the well called Byrgir, carrying between them on their shoulders the pole called Simul with the pail called Soeg. Vidfinn was the name of their father. These children follow Mani, as can be seen from the earth.’
