Pryderi

In Welsh mythology, King Pryderi of Dyfed was the son of Pwyll and Rhiannon.

On the night of his birth, he disappeared while in the care of six of Rhiannon's ladies-in-waiting. To avoid the blame, they smeared blood from a puppy on Rhiannon, who was asleep, and claimed that she had eaten the boy.

Teyrnon, Lord of Gwent Is Coed, had a mare who gave birth each year but whose foals had all disappeared. Teyrnon watched his stables and saw a mysterious clawed beast coming to take the foal; Teyrnon cut off the beast's arm and found the child outside the stable. He and his wife adopted the boy, naming him Gwri Wallt Euryn (Gwri of the golden hair). The child grew to adulthood in only seven years and was given the foal which had led Teyrnon to the stable. Teyrnon realized who the child was and returned him to Pwyll and Rhiannon, who named him Pryderi (worry).

Pryderi married Cigva and became King of Dyfed after his father died. He then invited Manawydan to live with him in Dyfed. Soon, Dyfed turned into a barren wasteland and only Rhiannon, Pryderi, Cigva and Manawydan lived. Manaywdan and Pryderi, while out hunting, saw a white boar which they followed. Pryderi and his mother, Rhiannon, touched a golden bowl that the boar led them to and became enchanted. Manawydan and Cigva were unable to help them until they captured a mouse which was actually the wife of Llwyd, Rhiannon's enemy, and the spell was lifted.

Later, Pryderi had his pigs stolen by Gwydion, thus starting a war between Pryderi and Math ap Mathonwy.
