Sól is referenced in the "Prose Edda" book "Gylfaginning", where she is introduced in chapter 8 in a quote from stanza 5 of "Völuspá". In chapter 11 of "Gylfaginning", Gangleri (described as King Gylfi in disguise) asks the enthroned figure of High how the Sun and Moon are steered. High describes that Sól is one of the two children of Mundilfari, and states that the children were so beautiful they were named after the Sun (Sól) and the Moon (Máni). Mundilfari has Sól married to a man named Glenr.
