It may not be unprofitable to inquire what idea Tennyson probably intended to symbolize by the “Holy Grail,” and the quest for it. Is it that of mere supernatural portent? Certainly not. The whole treatment suggests far more. I used to think it signified the mystical blood of Christ, the spirit of self-devotion, or, as Mallory defines it, “the secret of Jesus.” But it scarcely seems possible that Tennyson means precisely that, for then his ideal man Arthur would not discourage the quest. Does it not rather stand for that secret of the higher life as sought in any form of supernatural religion, involving acts of worship or asceticism, and religious contemplation? Yet Arthur deprecates not the religious life as such—rather that life in so far as it is not the auxiliary of human service. It is while pursuing the quest that Percivale (in the “Holy Grail”) finds all common life, even the most sacred relations of it, as well as the most ordinary and vulgar, turn to dust when he touches them; and to a religious fanatic that is indeed the issue—this life is less than dust to him; he exists for the future and “supernatural” only; his soul is already in another region than this homely work-a-day world of ours; and because it is another, he is only too ready to think it must be higher. What to him are our politics, our bewilderments, our fair humanities, our art and science, or schemes of social amelioration? Less than nothing. What he has to do is to save first his own soul, and then some few souls of others, if he can. But while, as Arthur himself complained, such an one waits for the beatific vision, or follows “wandering fires” of superstition, how often, for men with strength to right the wronged, will “the chance of noble deeds come and go unchallenged!” Arthur even dares to call the Holy Grail “a sign to maim this order which I made.” “Many of you, yea most, return no more.” But, as the Queen laments, “this madness has come on us for our sins.” Percivale turns monk, Galahad passes away to the spiritual city, Sir Bors meets Lancelot riding madly all abroad, and shouting, “Stay me not; I have been the sluggard, and I ride apace, for now there is a lion in the path!” Lancelot rides on the quest in order that, through the vision of the Grail, the sin of which his conscience accuses him may be rooted out of his heart. And so it was partly the sin—the infidelity to their vows—that had crept in amongst the knights, which drove the best of them to expiation, to religious fervors, whereby their sin might be purged, thus completing the disintegration of that holy human brotherhood, which had been welded together by Arthur for activities of righteous and loving endeavor after human welfare. Magnificent is the picture of the terrible, difficult quest of Lancelot, whose ineradicable sin hinders him from full enjoyment of the spiritual vision after which he longs. Nor will Arthur unduly discourage those who have thus in mortal peril half attained.
