It is a common saying that anything may happen behind our backs: transcendentally considered, the thing has an eerie truth about it. Eden may be behind our backs, or Fairyland. But this mystery of the human back has, again, its other side in the strange impression produced on those behind: to walk behind anyone along a lane is a thing that, properly speaking, touches the oldest nerve of awe. Watts has realised this as no one in art or letters has realised it in the whole history of the world; it has made him great. There is one possible exception to his monopoly of this magnificent craze. Two thousand years before, in the dark scriptures of a nomad people, it had been said that their prophet saw the immense Creator of all things, but only saw Him from behind.
'G. F. Watts.'
