"When I Heard the Learn'd Astronomer"

By Walt Whitman

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.
