Then, turning again to the magicians, Merlin said, �Tell me now, false sycophants, what there is underneath that pool?��but they were silent. Then said he to the king, �Command this pool to be drained, and at the bottom shall be found two dragons, great and huge, which now are sleeping, but which at night awake and fight and tear each other. At their great struggle all the ground shakes and trembles, and so casts down thy towers, which, therefore, never yet could find secure foundations.�
The king was amazed at these words, but commanded the pool to be forthwith drained; and surely at the bottom of it did they presently discover the two dragons, fast asleep, as Merlin had declared.
But Vortigern sat upon the brink of the pool till night to see what else would happen.
Then those two dragons, one of which was white, the other red, rose up and came near one another, and began a sore fight, and cast forth fire with their breath. But the white dragon had the advantage, and chased the other to the end of the lake. And he, for grief at his flight, turned back upon his foe, and renewed the combat, and forced him to retire in turn. But in the end the red dragon was worsted, and the white dragon disappeared no man knew where.
