Rhiannon is a goddess of horses and belongs to 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 later, the wife of Manawydan. Rhiannon is one of the first Celtic deities. Her name derives from the early British form Rigantona, meaning "great queen goddess". Her name also means “white witch”. She is associated with horses of the First Branch and may be related to Epona. Rhiannon is a good witch, a healer. She can manifest her dreams and desires. She travels on a white horse with mysterious birds with healing powers. In the First Branch, the Demetian King Pwyll sees Rhiannon. She is a beautiful woman dressed in silky golden brocade and she rides a white horse. It takes several days before Pwyll attracts 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 outwitting and disgracing 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 into the hands of Rhiannon's ladies-in-waiting. Rhiannon is accused of eating her own 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 gold in color. As he grew older, he reached a superhuman pace and his resemblance to Pwyll was noticeable. He reunited with Pwyll and Rhiannon and they changed his name to Pryderi, meaning "loss".

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 demanded the release of the mist. The bishop granted Manawydan's requests. The bishop was actually Llwyd ap Cil Coed, the mice were his servants, and the captured mouse was Llwyd's pregnant wife, Gwenaby. It had turned out that Llwyd was seeking revenge for the humiliation of his friend Gwawl ap Clud by Pwyll and Rhiannon. The fog over Dyfed was then lifted. The Mabinogi no longer saw Rhiannon as anything more than human. Nevertheless, Rhiannon may be an earlier goddess of Celtic polytheism. Rhiannon comes from two archetypes of myth: a beautiful goddess queen and a wife wrongly accused of killing her only son.
