Christina Georgina Rossetti

Fata Morgana

A blue-eyed phantom far before
  Is laughing, leaping toward the sun;
Like lead I chase it evermore,
  I pant and run.

It breaks the sunlight bound on bound;
  Goes singing as it leaps along
To sheep-bells with a dreamy sound
  A dreamy song.

I laugh, it is so brisk and gay;
  It is so far before, I weep:
I hope I shall lie down some day,
  Lie down and sleep.
