Coral

Full fathom five thy father lies;
Of his bones are coral made;
Those are pearls that were his eyes:
Nothing of him that doth fade,
But doth suffer a sea-change
Into something rich and strange.
Sea-nymphs hourly ring his knell:
                                             Ding-dong.
Hark! now I hear them,—ding-dong, bell.

From William Shakespeare's The Tempest
