Rhiannon

Rhiannon figures in the Welsh Medieval tales of teh Mabinogi, as an otherworldly figure who choses Pwyll, Prince of Dyfed (West Wales) to be her consort. She rides a magical white horse which it is impossible for Pwyll's men, or Pwyll himself to catch up with, until her addresses her in teh proper manner. Some scholars believe that Rhiannon's name was originally Rigantona, "the Great Queen", a nd that she was a goddess of Sovereignty. Horses, particularly white horses were often associated with teh sovereignty of teh land in Celtic cultures. Some associate Rhiannon with Epona, the Gaulish and Romano-Celtic Horse Goddess. Rhiannon is also associated with magical birds.
