In the hall of his Roman palace at London, King Uther, Pendragon of the Island of Britain, lay dying. He had been long sick with a wasting disease, and forced to lie in his bed, gnawing his beard with wrath at his weakness, while the pagan Saxons ravened up and down the fair broad lands, leaving in their tracks the smoking ruin of broken towns and desolated villages, where mothers lay dead beside their children on the hearths, fair churches stood pillaged and desecrated, and priests and nuns wandered in the wilds.

At length, when the pagans, bold and insolent, had ventured near London, the king had been able to bear his shame and anguish no longer. He had put himself, in a litter, at the head of his army, and meeting the fierce, brave pagans at Verulam (now called St. Albans) he had, in a battle day-long and stubborn, forced them at length to fly with heavy slaughter.

That was three days ago, and since then he had lain in his bed as still as if he were dead; and beside him sat the wise wizard Merlin, white with great age, and in his eyes the calmness of deep learning.

It was the third night when the king suddenly awoke from his stupor and clutched the hand of Merlin.

'I have dreamed!' he said in a low shaken voice. 'I have seen two dragons fighting--one white, the other red. First the white dragon got the mastery, and clawed with iron talons the red one's crest, and drove him hither and thither into holes and crannies of the rocks. And then the red one took heart, and with a fury that was marvellous to see, he drove and tore the white dragon full terribly, and anon the white one crawled away sore wounded. And the red dragon walked up and down in the place of his triumph, and grew proud, and fought smaller red dragons and conquered. Thus for a long time he stayed, and was secure and boastful.
