Superstition

In the waste places, in the dreadful night,
  When the wood whispers like a wandering mind,
  And silence sits and listens to the wind,
  Or, 'mid the rocks, to some wild torrent's flight;
  Bat-browed thou wadest with thy wisp of light
  Among black pools the moon can never find;
  Or, owlet-eyed, thou hootest to the blind
  Deep darkness from some cave or haunted height.
  He who beholds but once thy fearsome face,
  Never again shall walk alone! but wan
  And terrible attendants shall be his--
  Unutterable things that have no place
  In God or Beauty--that compel him on,
  Against all hope, where endless horror is.
