concerning hidden beauty

                                              ...macro detail of a frozen waterfall deep in  the winter woods of Maine

(The stars) then, though unbeheld in deep of night,

Shine not in vain; nor think, though men were none,

That Heaven would want spectators,  God want praise;

Millions of spiritual Creatures walk the Earth

Unseen, both when we wake, and when we sleep;

All these with ceaseless praise his works behold

Both day and night:  how often from the steep

Of echoing Hill or Thicket have we heard

Celestial voices to the midnight air,

Sole, or responsive each to other's note,

Singing their great Creator ?....

John Milton,   Paradise Lost  Book 4
