not return. Rhiannon goes to investigate and finds him clinging to a bowl, unable to speak. The same fate befalls her, and the castle disappears. Manawydan and Cigfa return to England as shoemakers, but once again the locals drive them out and they return to Dyfed. They sow three fields of wheat, but the first field is destroyed before it can be harvested. The next night the second field is destroyed. Manawydan keeps watch over the third field, and when he sees it destroyed by mice he catches their leader and decides to hang it. A scholar, a priest and a bishop in turn offer him gifts if he will spare the mouse, but he refuses. When asked what he wants in return for the mouse's life, he demands the release of Pryderi and Rhiannon, and the lifting of the enchantment over Dyfed.

The other child is raised by Gwydion, but Arianrhod tells him he will never have a name or arms unless she gives them to him, and refuses to do so. Gwydion tricks her into naming him Lleu Llaw Gyffes ("Bright, of deft hand"), and giving him arms. She then tells him he will never have a wife of any race living on Earth, so Gwydion and Math make him a wife from flowers, called Blodeuwedd (possibly "Flower face", though other
