There was a knight of Arthur’s band Who did great deeds by strength of hand But no wise would he be content Till Guinevere lay in his tent. Disloyalty was his downfall Without which he had had else all. “If only I had Guinevere” Quoth he, “There’s nought else I hold dear.” But all men know how that turned out In Caxton’s book of Arthur’s Morte. If Lancelot had not been false Then things had not come to this pass. But even in the courts of kings Man’s fatal defect evil brings And that’s why we can’t have nice things.
