from THE TEMPEST
act I scene II

Ariel: 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 do ring his knell:
                                                           (Burden: ding-dong.
Hark! now I hear them. - ding-dong, bell.
