Mundilfari. She is married to Glen. Sol rides through the sky in a chariot pulled by the horses Alsvid ("all swift") and Arvak ("early riser"). Below their shoulder-blades the gods inserted iron-cold bellows to keep them cool.
She is chased during the daytime by the wolf Skoll who tries to devour her, just like her brother Mani is chased by the wolf Hati at night. It was believed that during solar eclipses the sun was in danger of being eaten by Skoll. Both wolves are the offspring of the giantess Hrodvitnir who lives in the Iron Wood. Eventually, the wolf will catch her. The goddess Svalin stands in front of the sun and shields the earth from the full intensity of its heat.
The Vikings believed that when the two wolves caught up with the sun and moon, they would swallow them and all the stars would disappear from the sky. It would be a signal that Ragnarok, the battle between the forces of good and the forces of evil, was about to begin, and that the end of the world was at hand.
