Rhiannon, Celtic Goddess of the moon and inspiration. The enchanting fairy princess who rode so swiftly that no horseman could catch her, loved and chose to marry a mortal king of Wales. Accused of murdering their infant son, Rhiannon bore her humiliating punishment with a grace and dignity that melted the hearts of her adopted countrymen.
Eventually proven innocent, Rhiannon was reunited with her husband and son and restored to her throne. Later the Celtic Goddess Rhiannon became the famous Lady of the Lake who, in the legends of Camelot, gave Arthur the magical sword called Excalibur.
Rhiannon (her name is either "Maid of Annwn" or a variant of Rigatona, "Great Queen"), a version of the horse goddess Epona and of sovereignity. She was mistress of the Singing Birds. She appeared to Pwyll lord of Dyfed, as a beautiful woman in dazzling gold on a white horse. Pwyll sent his fastest horsemen after her, but could not catch her. On the third day, he spoke and she told him she wanted to marry him instead of her espoused husband Gwawl. Pywll was to meet her in a year and a day.
He won her at the court of her father, Hefeydd the Old, by her aid. She bore Pwyll a son, who vanished. Her women killed a puppy and smeared its blood on her, to avoid blame at the child's loss. As punishment, Rhiannon spent seven years telling her story to all comers and bearing them, like a horse, to the court.
The child, meanwhile, turned up at the court of Teyrnon, whose mares foaled on May eve and lost the foals mysteriously. When Teirnon kept watch, he saved a foal from a mysterious beast and also discovered, outside the stable, a child, whom he and his wife adopted. Then child grew to young manhood in seven years, and was given the foal rescued on the night he was found. Teirnon recognised the child as the son of Pwyll and returned him to his family, where he was named Pryderi ("worry") by his mother.
Later, after Pwyll's death, Rhiannon married Manawydan, brother of Bran and Branwen and son of Llyre a great magician. One day, all of Dyfed turned into a wasteland, and only Rhiannon, Manawydan, Pryderi, and his wife Cigfa, were spared. Manawydan and Pryderi were out hunting following an enormous white boar into a caer,( caer or kaer was a royal residence during the 1st millennium AD or earlier. Caer can be loosely translated castle or palace or fort)where Pryderi saw a golden bowl; when he touched it, he was en - spelled. Rhiannon went after him and fell under the same spell the caer then vanished, taking them with it. She was rescued when Manawydan captured the wife of their enemy, Llwyd, who was taking revenge for the ill treatment of Gwawl.
