When I heard the learned 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 wandered off by myself,
In the mystical moist night air, and from time to time,
Looked up in perfect silence at the stars.
Walt Whitman, “When I Heard the Learn’d Astronomer” (1865) from Leaves of Grass
