Sol is a deity in Norse Mythology. She represents the personification of the Sun in. Her name indeed means "sun".
Few sources testify to a personification of the sun. Some sources evoke the goddess Sunna. In Scandinavian poetry, the sun is only definitely personified in the Vafþrúðnismál, where the giant Vafþrúðnir indicates that Mundilfœri is the father of Mani and Sol, who must turn every day in the sky.
From a stanza and the Grímnismál, Snorri Sturluson evokes in more detail the character of Sol, whom he counts among the goddesses. The Gylfaginning reports that a man named Mundilfœri had two children, so beautiful that he named them, one Mani (Moon), the other Sol (Sun), whom he had married to Glenr.
Annoyed by this claim, the gods placed the brother and sister in the sky, where Sol drives the horses Arvak and Alsvid, which pull the sun's chariot, and where Mani controls the course of the Moon. Sol is pursued by the wolf Skoll, who eventually catches her at Ragnarok.
Sol has a daughter who is as beautiful as her mother. She continues her mother's task of driving the sun across the sky after her mother's death.
Another tradition in Norse mythology, however, concerns the horse Skinfaxe, who draws the sun across the sky.
Sunday is an ancient Norse and Germanic day of the week named after the sun. In the runic alphabet, the rune of the sun is represented by Sowilo.
