- In Celtic myth the son of Penard’un by her first marriage, and stepbrother of Brân, King of Britain, and Branwen. By spite he caused the hatred between them and Matholwch, and later, when a reconciliation was on the point of being arranged, he burnt his nephew Gwern, the son of Branwen and Matholwch, to death, and killed himself by jumping into Llassar’s Cauldron of Rebirth. In another version he received the cauldron from Brân and proceeded with it to Ireland as an emissary. There he allied himself with Mathlwch and slew his stepbrother in the ensuing war. The story of the embittered hatred of the displaced heir to the throne, for his stepbrother, the King of Britain, and his stepsister, the Queen of Ireland, has within it a tragic element of historical truth.
