As for the shriek, Llevelys explained it to be raised by a dragon. This monster was the Red Dragon of Britain, and it raised the shriek because it was being attacked by the White Dragon of the Saxons, which was trying to overcome and destroy it. The French king told his brother to measure the length and breadth of Britain, and, when he had found the exact centre of the island, to cause a pit to be dug there. In this pit was to be placed a vessel containing the best mead that could be made, with a covering of satin over it to hide it. Lludd was then to watch from some safe place. The dragons would appear and fight in the air until they were exhausted, then they would fall together on to the top of the satin cloth, and so draw it down with them into the vessel full of mead. Naturally they would drink the mead, and, equally naturally, they would then sleep. As soon as Lludd was sure that they were helpless, he was to go to the pit, wrap the satin cloth round both of them, and bury them together in a stone coffin in the strongest place in Britain. If this were safely done, there would be no more heard of the shriek. And the disappearance of the food was caused by “a mighty man of magic”, who put everyone to sleep by charms before he removed the king’s provisions. Lludd was to watch for him, sitting by the side of a cauldron full of cold water. As often as he felt the approach of drowsiness, he was to plunge into the cauldron. Thus he would be able to keep awake and frustrate the thief. So Lludd came back to Britain. He pounded the insects in the water, and then summoned both the men of Britain and the Coranians to a meeting. In the midst of it, he sprinkled the water over everyone alike. The natives took no harm from this mythological “beetle powder”, but the Coranians died. Lludd was then ready to deal with the dragons. His careful measurements proved that the centre of the island of Britain was at Oxford, and there he caused the pit to be dug, with the vessel of mead in it, hidden by the satin covering. Having made everything ready, he watched, and soon saw the dragons appear. For a long time they fought desperately in the air; then they fell down together on to the satin cloth, and, drawing it after them, subsided into the mead. Lludd waited till they were quite silent, and then pulled them out, folded them carefully in the wrapping, and took them to the district of Snowdon, where he buried them in the strong fortress whose remains, near Beddgelert, are still called “Dinas Emrys”. After this the terrible shriek was not heard again until Merlin had them dug up, five hundred years later, when they recommenced fighting, and the red dragon drove the white one out of Britain.
