When I Heard the Learned Astronomer

Walt Whitman, 1819 - 1892
When I heard the learn'd astronomer, 
When the proofs, the figures, were ranged in columns before me, 
When I was shown the charts and diagrams, to add, divide, 
   and measure them,
When I sitting heard the astronomer where he lectured with
   much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander'd off by myself,
In the mystical moist night-air, and from time to time, 
Look'd up in perfect silence at the stars.

poem
Out of the cradle endlessly rocking,
Out of the mocking-bird's throat, the musical shuttle,
Out of the Ninth-month midnight,
Over the sterile sands and the fields beyond, where the child 
   leaving his bed wander'd alone, bareheaded, barefoot,
Down from the shower'd halo,
Up from the mystic play of shadows
poem
Spontaneous me, Nature,   
The loving day, the mounting sun, the friend I am happy with,   
The arm of my friend hanging idly over my shoulder,   
The hill-side whiten’d with blossoms of the mountain ash,   
The same, late in autumn—the hues of red, yellow, drab, purple, and light and dark green,
The rich
poem
On the beach at night alone,	 
As the old mother sways her to and fro, singing her husky song,	
As I watch the bright stars shining, I think a thought of the clef of the universes, and of the future.	 
  
A vast similitude interlocks all,	 
All spheres, grown, ungrown, small, large, suns, moons, planets	
All
