When I Heard the Learn'd Astronomer

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 the 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.
