RHIANNON pronounced [R'HEE-awn-on] is a Welsh or Cornish name that translates as "divine" or "great queen." She is a symbol of fertility, yet she is also an Otherworld and death Goddess, a weaver of dreams, and a moon deity who is symbolized by a white horse. Her father was Heveydd the Old.

Rhiannon, riding her pure white horse, appeared to her future husband Pwyll three different times before he was allowed to catch her. Though promised in marriage to Gwawl Ap Clud, a minor sun deity, she was determined to have Pwyll. He went to ask for her hand, instead was tricked into giving her to Gwawl as a matter of honor. A year and a day later Rhiannon used her magick, a bit of conspiracy, and the guise of honor, to get away from Gwawl. Gwawl followed them, but Pwyll caught him up in a bag and then tried to have him slain by telling everyone he was a badger.

In her guise as a death Goddess, Rhiannon could sing sweetly enough to lure all in hearing to their deaths, and therefore she may be related to Germanic stories of lake and river faeries who sing seductively to lure sailors and fishermen to their deaths.
