"King Ludd," we are told in The Mabinogion, "ruled prosperously and rebuilt the walls of London, and encompassed it about with numberless towers. And after that he bade the citizens build houses therein, such as no houses in the kingdom could equal. And, moreover, he was a mighty warrior, and generous and liberal in giving meat and drink to all that sought them. And though he had many castles and cities, this one loved he more than any. And he dwelt therein most part of the year, and therefore was it called Caer Ludd, and at last Caer London. And after the strange race came there, it was called London." It is interesting to remember that there is still a street in London called Ludgate. Caer is the Celtic word for Castle, and is still to be found in many Welsh names, such as Carnarvon, Caerleon, and so on.

Now, although Ludd was such a wise king, three plagues fell upon the island of Britain. "The first was a certain race that came and was called Coranians, and so great was their knowledge that there was no discourse upon the face of the island, however low it might be spoken, but what, if the wind met it, it was known to them.

"The second plague was a shriek which came on every May-eve over every hearth in the island of Britain. And this went through peoples' hearts and frightened them out of their senses.

"The third plague was, however much of provision and food might be prepared in the king's courts, were there even so much as a year's provision of meat and drink, none of it could ever be found, except what was consumed upon the first night."

The story goes on to tell how good King Ludd freed the island of Britain from all three plagues and lived in peace all the days of his life.

In five of the stories of The Mabinogion, King Arthur appears. And, although these were all written in Welsh, it has been thought that some may have been brought to Wales from France.

This seems strange, but it comes about in this way. Part of France is called Brittany, as you know. Now, long long ago, before the Romans came to Britain, some of the people who lived in that part of France sailed across the sea and settled in Britain. These may have been the ancient Britons whom Caesar fought when he first came to our shore.

Later, when the Romans left our island and the Picts and Scots oppressed the Britons, many of them fled back over the sea to Brittany or Armorica, as it used to be called. Later still, when the Saxons came, the Britons were driven by degrees into the mountains of Wales and the wilds of Cornwall, while others fled again across the sea to Brittany. These took with them the stories which their minstrels told, and told them in their new home. So it came about that the stories which were told in Wales and in Cornwall were told in Brittany also.

And how were these stories brought back again to England?

Another part of France is called Normandy. The Normans and the Bretons were very different peoples, as different as the Britons and the English. But the Normans conquered part of Brittany, and a close relationship grew up between the two peoples. Conan, Duke of Brittany, and William, Duke of Normandy, were related to each other, and in a manner the Bretons owned the Duke of Normandy as overlord.
