Rhiannon is a goddess of horses and is from Welsh mythology. Rhiannon is found in the Mabinogion in the First and Third Branches. She is the mother of the hero Pryderi, king of Dyfed, and the wife of Pwyll and then, later, the wife of Manawydan. Rhiannon is one of the earliest Celtic deities. Her name comes from the ancient British name Rigantona, meaning "great queen goddess". Her name also means "white witch". She is associated with the First Branch horses and may be related to Epona. Rhiannon is a good witch, a healer. He can manifest his dreams and desires. He travels on a white horse with mysterious birds that bring healing powers. In the first branch, the Demetic king Pwyll sees Rhiannon. She is a beautiful woman dressed in silky golden brocade and rides a white horse. It takes several days for Pwyll to get his attention. She tells him that she would rather marry him than her fiancé, Gwawl ap Clud. A year later Pwyll accidentally promises Gwawl to Rhiannon. He wins her back by deceiving and dishonoring Gwawl. Pwyll and Rhiannon marry and attempt to produce an heir to the kingdom. Eventually a boy is born, and on the night of his birth he disappears while in the hands of Rhiannon's ladies-in-waiting. Rhiannon is accused of eating her son and is forced to do penance for her crime. The boy is found outside a stable by Teyron, the lord of Gwent Is Coed. He and his wife raised the child and named him Gwri Walt Euryn, meaning golden-haired Gwri because the hair on his head was the color of gold. As he grew older he grew to a superhuman pace and his resemblance to Pwyll was evident. He was reunited with Pwyll and Rhiannon and they changed his name to Pryderi, meaning "loss". Pwyll dies peacefully and Pryd... middle of paper... in all three offerings. The bishop then asked him what he wanted for the mouse's life and he replied that he wanted the release of his wife and son. He also called for the fog to be released. The bishop accepted Manawydan's requests. The bishop was actually Llwyd ap Cil Coed, the mice were his attendants, and the captured mouse was Llwyd's pregnant wife, Gwenaby. It was revealed that Llwyd was seeking revenge for Pwyll and Rhiannon's humiliation of his friend Gwawl ap Clud. The fog over Dyfed was then lifted. The Mabinogi saw Rhiannon as nothing more than a human. However, Rhiannon may be an earlier goddess of Celtic polytheism. Rhiannon derives from two archetypes of myth: a beautiful queen goddess and a wife wrongly accused of killing her only son. Some people see her as a horse goddess related to Epona due to her association with horses..
