Slowly the barge floated down the river until it had come to Westminster; and as it passed under the palace walls, it chanced that King Arthur and Queen Guenevere looked forth from a window. Marvelling much at the strange sight, together they went forth to the quay, followed by many of the knights. Then the King espied the letter clasped in the dead maiden's hand, and drew it forth gently and broke the seal. And thus the letter ran: "Most noble Knight, Sir Launcelot, I, that men called the Fair Maid of Astolat, am come hither to crave burial at thy hands for the sake of the unrequited love I gave thee. As thou art peerless knight, pray for my soul."

Then the King bade fetch Sir Launcelot, and when he was come, he showed him the letter. And Sir Launcelot, gazing on the dead maiden, was filled with sorrow. "My lord Arthur," he said, "for the death of this dear child I shall grieve my life long. Gentle she was and loving, and much was I beholden to her; but what she desired I could not give." "Yet her request now thou wilt grant, I know," said the King; "for ever thou art kind and courteous to all." "It is my desire," answered Sir Launcelot.

So the Maid of Astolat was buried in the presence of the King and Queen and of the fellowship of the Round Table, and of many a gentle lady who wept, that time, the fair child's fate. Over her grave was raised a tomb of white marble, and on it was sculptured the shield of Sir Launcelot; for, when he had heard her whole story, it was the King's will that she that in life had guarded the shield of his noblest knight, should keep it also in death.

HOW MORDRED PLOTTED AGAINST SIR LAUNCELOT

Stories from Le Morte D'Arthur and the Mabinogion — Part 80

Before Merlin passed from the world of men, imprisoned in the great stone by the evil arts of Vivien, he had uttered many marvellous prophecies, and one that boded ill to King Arthur; for he foretold that, in the days to come, a son of Arthur's sister should stir up bitter war against the King, and at last a great battle should be fought in the West, when many a brave knight should find his doom.

Now, among the nephews of Arthur, was one most dishonourable; his name was Mordred. No knightly deed had he ever done, and he hated to hear the good report of others because he himself was a coward and envious. But of all the Round Table there was none that Mordred hated more than Sir Launcelot du Lac, whom all true knights held in most honour; and not the less did Mordred hate Launcelot that he was the knight whom Queen Guenevere had in most esteem. So, at last, his jealous rage passing all bounds, he spoke evil of the Queen and of Launcelot, saying that they were traitors to the King. Now Sir Gawain and Sir Gareth, Mordred's brothers, refused to give ear to these slanders, holding that Sir Launcelot, in his knightly service of the Queen, did honour to King Arthur also; but by ill-fortune another brother, Sir Agravaine, had ill-will to the Queen, and professed to believe Mordred's evil tales. So the two went to King Arthur with their ill stories.
