I was particularly enthralled by one of the middle paintings. It was the one in which Galahad had encountered the three women. I believe them to have been trying to stop him from getting to the grail by distracting him with magic and what not. The older women, or the head "damsel" I would presume reminded me a lot of Morgan La Fay. She was on a horse wore a red cloak, and carried the kings head in her arms. And the other women reminded me of myself, though of course, it was not.
But Galahad, as we know was so truthful and pure of a man. He resisted all the temptation he had encountered--ultimately finding the grail in later paintings and becoming a king himself. I can give credit where it is due--well done Galahad!
