How Gawain Put His Impertinence on Hold and Took Up an Adventure
In the days of Arthur, it was the custom at Camelot to await the onset of a marvel before sitting down to Sunday dinner. One particular Sunday in spring, when it was raining, the King had almost decided to forgo his usual custom for that day, due to dampness, when a sudden breeze penetrated the hall, slamming all the doors and nearly blowing out the candles. A single beam of piercing light entered through a high embrasure, and a sweet odor filled the air with a wonderful fragrance. Before the astonished eyes of the court, a shining cup appeared, shedding a soft radiance through the silky veil that covered it as it wafted gently over the heads of all assembled. When the ladies and gentlemen looked at one another in the strange light, each appeared as his or her best self, astonishing in grace and comeliness.
Speechless as they were, each went quietly to his or her seat, wondering at the beauty evident now in every face. None of them had ever looked so fair! Silently, as the cup passed over each of them, all of the things he or she loved best to eat and drink suddenly appeared. Once everyone had been served, a crack of thunder and a sharp blaze of lightning occurred simultaneously, and the court was momentarily blinded. When they could see again, the cup was gone, but something of its soft light still shimmered in the hall, and the odor of rare and precious flowers and elixirs lingered delightfully.
Breaking the deep and profound silence, Arthur said, well, we have seen a marvel this day, for certain. I wonder if any assembled here can explain the meaning of this thing.
The king's bard spoke up then, saying, I have heard tell of a wonderful cup from the Otherworld, a Grail of plenty, but the stories, truly, do not do it justice, from what I have just seen. It is said that when the Grail appears, it heralds the start of a great quest, and those who make it their business to seek it will have many adventures. Yet few who seek it shall ever find it. It is a high quest, but perilous.
And the purpose of this quest? Arthur asked. For if any of my people were to undertake this adventure, I would have them know to what end.
It is said, sire, that the meaning only becomes clear to the one seeking, who may then return to reveal it to others. The appearance is a rare gift and carries no obligation, except for the one called to follow the Grail.
Gawain, who sat near the king and was known for his surly and outspoken disposition, surprised them all by saying, I have a mind to seek this thing, although I do not know the reason. I have not much use for nonsense, but this Grail has moved me. It's a thing I will never forget.
You, Gawain? said the king in surprise. I would have thought Perceval, or Galahad . . . and he gestured towards these two noble knights, known for their high-minded and spiritual natures. Yet neither of them spoke.
Yes, you doubt that I am the one for the job, said Gawain. But after all, an irreverent fool may be best suited to such a strange adventure and may succeed where the pious fail.
No one doubts your courage, Sir Gawain, but I would have thought that a more tender nature . . .
It is hard to say what one may encounter on the way, said Gawain, and they all could see that he was determined to go (and many in the hall that day, though they ate and drank all the good things gladly, were happy with all their hearts that someone else undertook the quest).
Two days later, Gawain, fully appareled as befits a knight, took his leave of them. All of the deep and winding ways he traveled would be a long tale to tell, though he encountered nothing out of the way for a knight used to deeds of errantry. (Truth be told, Perceval or Galahad might have fared differently, but Gawain was notoriously level-headed, and marvels tended to stay out of his way.) At the end of two weeks' ride, which took him well beyond the borders of the king's lands, he found himself at the edge of a sea, with a storm coming on.
Strange though it seemed, he descried many lights far out across the water, though in the darkness, he could not tell what they might signify. Stepping forward into the surf, he found the beginnings of a stone causeway beneath his feet. As the moon rose, he began to see the vague outline of a castle whose many windows glimmered through the rain. Climbing onto his horse, he set off at a gallop, hoping to reach the gates before the storm broke in earnest.
In that, however, he was disappointed, since no matter how hard he rode, the castle never seemed to draw nearer. On and on he went, with the rain in his eyes and the wind in his hair, with huge waves crashing across the causeway, almost as if they would wash it away before his eyes. Yet he rode on, never stinting, and after what seemed endless hours on the causeway in the howling storm, he at last discerned the gates. As he slowed his horse to a walk, he noticed a faint glimmer in the churning sea on either side. Looking down, it seemed to him that there were faces in the water, though, he thought, it might have been the merest fancy.
If Galahad were here, he said to himself, he would doubtless believe he had seen mermaids and mermen and even a selkie. I am not so sure that it isn't some type of sea creature, because, for certain, the light is bad, and being a landsman, the sea is strange to me. Perhaps it is what they call dolphins or some other fish.
Riding up to the gate, he gave it a hard knock with his fist, whereupon the metal grate rose and the wooden doors swung inward into a spacious forecourt with columns, hanging greenery, and a plashing fountain. The doors closed behind him immediately, shutting out the sounds of the storm. He might have been, he thought, at any richly endowed castle in Logres or Brittany. A squire came forward to take his horse, and Gawain climbed a set of wide carpeted steps toward a lighted doorway.
