Now at that time there was a very wise and learned physician in the camp of King Arthur, and one day Sir Gawaine sent for this learned man to come to him. When that wise man stood before Sir Gawaine, Sir Gawaine said to him this, “Sir, can you not produce for me a lotion that shall render me free from all wounds of any sort?”
The wise man provides medicine for Sir Gawaine.
Quoth the wise man, “Sir, this is impossible. But I can give to you a medicine of this sort, that if you take it, you will, from the ninth hour of morning until the prime of noon, have the strength in your limbs and in your arms as of ten men.” Sir Gawaine laughed, and said, “Provide me then with that medicine.”
So the wise man prepared that medicine and gave it to Sir Gawaine, and so it was for him as that physician had promised. For from the ninth hour of the morning until the prime of noon, Sir Gawaine was uplifted in arm and body to the strength of ten men.
Sir Gawaine giveth challenge against Sir Launcelot.
So the next day after this medicine had been delivered to him, Sir Gawaine went to the walls of the castle and he paraded under the walls of the castle, and he called out, “Sir Launcelot, come forth and do me battle. For this satisfaction thou owest to me for slaying my kindred.” But Sir Launcelot would not come forth to do him battle. For Sir Launcelot still loved Sir Gawaine and he loved King Arthur; both for the sake of those times that were past and gone, when they had joy and pleasure together. So because that the one was Sir Gawaine and the other was King Arthur, he would not come forth to do battle. Nay, because of his love for those two, Sir Launcelot would not fight in that part of the battle where Sir Gawaine or King Arthur was, but would do battle at other parts.
But when the next day had come, Sir Gawaine came again and the strength of ten men was in his arms and his body. And he paraded back and forth under the walls of the castle, and ever as he paraded he cried out aloud, “Sir Launcelot, thou caitiff knight! Come forth and do me battle! For thy doom is upon thee, and thou shalt die in this war; wherefore, come and do me battle, or else announce that thou art afraid of me.”
But still Sir Launcelot would not go forth against him, but he sat in the castle and groaned for sorrow and bitterness of spirit. Then Sir Ector came to Sir Launcelot, and he said, “Kinsman, suffer me that I go forth and do battle in thy behalf; for this man sharneth us by this challenge.”
Then Sir Launcelot wept, and he said, “Thou shalt not go, for wit you that I loved this man better than mine own blood. And if he should be slain, then will my heart be filled with grief such as can never vacate it again. And if thou art killed, then will I be without my brother, and must take it upon me to fight Sir Gawaine upon the behalf of thy death. Wherefore, I pray thee go not forth to meet him.”
But ever Sir Ector besought Sir Launcelot saying, “Brother, suffer me to go!” And at last Sir Launcelot said, “Well go, and may God be with thee!”
