Y Ddraig Goch

“In "Lludd and Llefelys," a related but distinct account, the two dragons' fighting is described as a yearly plague upon Britain, ended when King Lludd traps both dragons in a cauldron of mead at the centre of the island (Oxford) and then buries them at Dinas Emrys, the same hill later associated with Vortigern and the boy-prophet.”
