I, Galahad, saw the Grail,
The Holy Grail, descend upon the shrine:
I saw the fiery face as of a child
That smote itself into the bread, and went;
And hither am I come; and never yet
Hath what thy sister taught me first to see,
This Holy Thing, failed from my side, nor come
Covered, but moving with me night and day,
Fainter by day, but always in the night
Blood-red, and sliding down the           marsh
Blood-red, and on the naked mountain top
Blood-red, and in the sleeping mere below
Blood-red.
