This is the ship of pearl, which, poets feign,
  Sails the unshadowed main, --
  The venturous bark that flings
On the sweet summer wind its purpled wings
In gulfs enchanted, where the Siren sings,
  And coral reefs lie bare,
Where the cold sea-maids rise to sun their streaming hair.

Its webs of living gauze no more unfurl;
  Wrecked is the ship of pearl!
  And every chambered cell,
Where its dim dreaming life was wont to dwell,
As the frail tenant shaped his growing shell,
  Before thee lies revealed, --
Its irised ceiling rent, its sunless crypt unsealed!

Year after year beheld the silent toil
  That spread his lustrous coil;
  Still, as the spiral grew,
He left the past year's dwelling for the new,
Stole with soft step its shining archway through,
  Built up its idle door,
Stretched in his last-found home, and knew the old no more.

Thanks for the heavenly message brought by thee,
  Child of the wandering sea,
  Cast from her lap, forlorn!
From thy dead lips a clearer note is born
Than ever Triton blew from wreathèd horn!
  While on mine ear it rings,
Through the deep caves of thought I hear a voice that sings: --
