In Welsh mythology, Rhiannon was a daughter of Hefeydd the Old. She was married to Pwyll and, later, Manawydan.

"Rhiannon" is a popular single released by Fleetwood Mac in 1975. The song was the first example of Stevie Nicks' prolific writing, performing and singing within the band. In later years her performing and singing would become even more important in the band's artistry.

Wales. Goddess of birds and horses. She rides a white horse. Goddess of the Underworld.
