When I Heard the Learn’d Astronomer

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.

Walt Whitman (1819-1892)
