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