"On First Looking into Chapman's Homer," by John Keats

Much have I traveled in the realms of gold
And many goodly states and kingdoms seen;
Round many western islands have I been
Which bards in fealty to Apollo hold.
Oft of one wide expanse had I been told
That deep-browed Homer ruled as his demesne;
Yet never did I breathe its pure serene
Till I heard Chapman speak out loud and bold:
Then I felt like some watcher of the skies
When a new planet swims into his ken;
Or like stout Cortez* when with eagle eyes
He stared at the Pacific—and all his men
Looked at each other with a wild surmise—
Silent, upon a peak in Darien.

* I always loved the footnote in my Norton Anthology of English Literature on this line -- that it was Balboa, not Cortez, who first saw the Pacific "matters to history but not to poetry."
