"Look, Jessica, see how the floor of heaven
Is thick inlaid with patines of bright gold!
There's not the smallest orb that thou behold'st
But in his motion like an angel sings,
Still quiring to the young-eyed cherubim;
Such harmony is in immortal souls!
But whilst this muddy vesture of decay
Doth grossly close it in, we cannot hear it." 

    The Merchant of Venice  William Shakespeare
