HOW SWEET THE MOONLIGHT

How sweet the moonlight sleeps upon this bank!

Here will we sit and let the sounds of music

Creep in our ears; soft stillness and the night

Become the touches of sweet harmony.

Sit, Jessica. 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-ey'd cherubins;

Such harmony is in immortal souls,

But whilst this muddy vesture of decay

Doth grossly close it in, we cannot hear it
