The Song of Rhiannon The Third Branch of the Mabinogion

In the wake of the tragedy that befell the Children of LLyr, Prince Pryderi of Dyved returns to his realm with Manawyddan, the last survivor of the family. There Pryderi is reunited with his wife Cigfa and Manawydan marries Pryderi's mother Rhiannon. An enchantment descends on the land, leaving it a wasteland empty of all domesticated animals and humans apart from the four protagonists. They support themselves by hunting at first, then move to the larger realm of Llogres where they make a living making saddles, shields and shoes. Their work is of such quality that the local craftsmen cannot compete, and drive them from town to town.
