Arthur vs dragon

"My good sire, I truly carry a great sorrow because a serpent has carried off a friend of mine in such rough fashion that I fear he is dead."
"Damsel, where is this serpent?" And she showed him the direction it had flown off to. The Knight of the Parrot went in this direction, but did not continue long when he saw the most horrible serpent ever seen any-where, carrying in its mouth an armed knight who, because of his armor's protection, was still not dead. Then the Knight of the Parrot set his horse at a gallop and hastened to strike the serpent a blow on its chest with his lance, which penetrated right through its heart, so that the serpent, upon feeling the blow, let the knight fall down; then it rolled over again and again, and lashed its great winding tail, so that it seemed to be very much like a devil. It so thrashed its tail about, because of the death it felt gripping it, that, by mischance, it hit the Knight of the Parrot, striking him so hard that both he and his mount were thrown into some wide and deep water, and were it not for this lake, he would have been mortally wounded. Nonetheless, he was grievously wounded and totally poisoned by the serpent, which had stung him, and would have been in great peril, were it not for God's help.
When, with great difficulty, he finally came out of the water, he rode off in the direction he believed to be the best. He had scarcely continued for a league beyond the lake when he fainted from the effect of the poison coursing through him, and so he fell onto the ground, almost back into the water, and he was in such painful straits that he felt numb all over. When the knight whom the serpent had dropped from its mouth saw the snake dead, he went up to his damsel and asked her what had become of the knight who had killed it; she told him how she had met the other knight and how he had gladly accepted to go to his rescue.
