内容简介：
Alone at some distance from the wasting walls of a disused abbey I found half sunken in the grass the grey and goggle-eyed visage of one of those graven monsters that made the ornamental water-spouts in the cathedrals of the Middle Ages. It lay there, scoured by ancient rains or striped by recent fungus, but still looking like the head of some huge dragon slain by a primeval hero. And as I looked at it, I thought of the meaning of the grotesque, and passed into some symbolic reverie of the three great stages of art. - G.K. Chesterton
