On First Looking Into Chapman's Homer

"On First Looking Into Chapman's Homer" is a poem written by John Keats, first published in 1816. It is in the form of an Italian Sonnet. In the poem, Keats makes the mistake of claiming that it was Cortez who discovered the Pacific, when it was really Vasco Núñez de Balboa.

 On First Looking Into Chapman's Homer 
 Much have I travell'd 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-brow'd Homer ruled as his demesne;
 Yet never did I breathe its pure serene
 Till I heard Chapman speak out loud and bold.
 Then felt I like some watcher of the skies
 When a new planet swims into his ken;
 Or like stout Cortez, when with eagle eyes
 He star'd at the Pacific - and all his men
 Look'd at each other with a wild surmise -
 Silent, upon a peak in Darien.
 -- John Keats
