Beli the Great, the son of Manogan, had three sons, Lludd, and Caswallawn, and Nynyaw; and according to the story he had a fourth son called Llevelys.  And after the death of Beli, the kingdom of the Island of Britain fell into the hands of Llud his eldest son; and Lludd 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 kingdoms 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 Lludd, and at last Caer London.  And after the stranger-race came there, it was called London, or Lwndrys.

Lludd loved Llevelys best of all his brothers, because he was a wise and discreet man.  Having heard that the king of France had died, leaving no heir except a daughter, and that he had left all his possessions in her hands, he came to Lludd his brother, to beseech his counsel and aid.  And that not so much for his own welfare, as to seek to add to the glory and honour and dignity of his kindred, if he might go to France to woo the maiden for his wife.  And forthwith his brother conferred with him, and this counsel was pleasing unto him.

So he prepared ships and filled them with armed knights, and set forth towards France.  And as soon as they had landed, they sent messengers to show the nobles of France the cause of the embassy.  And by the joint counsel of the nobles of France and of the princes, the maiden was given to Llevelys, and the crown of the kingdom with her.  And thenceforth he ruled the land discreetly, and wisely, and happily, as long as his life lasted.

After a space of time had passed, three plagues fell on the Island of Britain, such as none in the islands had ever seen the like of.  The first was a certain race that came, and was called the 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.  And through this they could not be injured. [4]

The second plague was a shriek which came on every May-eve, over every hearth in the Island of Britain.  And this went through people’s hearts, and so scared them, that the men lost their hue and their strength, and the women their children, and the young men and the maidens lost their senses, and all the animals and trees and the earth and the waters, were left barren.

The third plague was, that however much of provisions 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 in the first night.  And two of these plagues, no one ever knew their cause, therefore was there better hope of being freed from the first than from the second and third.

And thereupon King Lludd felt great sorrow and care, because that he knew not how he might be freed from these plagues.  And he called to him all the nobles of his kingdom, and asked counsel of them what they should do against these afflictions.  And by the common counsel of the nobles, Lludd the son of Beli went to Llevelys his brother, king of France, for he was a man great of counsel and wisdom, to seek his advice.

And they made ready a fleet, and that in secret and in silence, lest that race should know the cause of their errand, or any besides the king and his counsellors.  And when they were made ready, they went into their ships, Lludd and those whom he chose with him.  And they began to cleave the seas towards France.

And when these tidings came to Llevelys, seeing that he knew not the cause of his brother’s ships, he came on the other side to meet him, and with him was a fleet vast of size.  And when Lludd saw this, he left all the ships out upon the sea except one only; and in that one he came to meet his brother, and he likewise with a single ship came to meet him.  And when they were come together, each put his arms about the other’s neck, and they welcomed each other with brotherly love.

After that Lludd had shown his brother the cause of his errand, Llevelys said that he himself knew the cause of the coming to those lands.  And they took counsel together to discourse on the matter otherwise than thus, in order that the wind might not catch their words, nor the Coranians know what they might say.  Then Llevelys caused a long horn to be made of brass, and through this horn they discoursed.  But whatsoever words they spoke through this horn, one to the other, neither of them could hear any other but harsh and hostile words.  And when Llevelys saw this, and that there was a demon thwarting them and disturbing through this horn, he caused wine to be put therein to wash it.  And through the virtue of the wine the demon was driven out of the horn.  And when their discourse was unobstructed, Llevelys told his brother that he would give him some insects whereof he should keep some to breed, lest by chance the like affliction might come a second time.  And other of these insects he should take and bruise in water.  And he assured him that it would have power to destroy the race of the Coranians.  That is to say, that when he came home to his kingdom he should call together all the people both of his own race and of the race of the Coranians............
