SPIRIT OF THE HOUR
  Soon as the sound had ceased whose thunder filled
  The abysses of the sky and the wide earth,
  There was a change; the impalpable thin air
  And the all-circling sunlight were transformed,
  As if the sense of love, dissolved in them,
  Had folded itself round the spherèd world.
  My vision then grew clear, and I could see
  Into the mysteries of the universe.
  Dizzy as with delight I floated down;
  Winnowing the lightsome air with languid plumes,
  My coursers sought their birthplace in the sun,
  Where they henceforth will live exempt from toil,
  Pasturing flowers of vegetable fire,
  And where my moonlike car will stand within
