A few more thoughts on the subject of how accurate we should be when we write poetry:
A few days ago, I had cause to look up Keats’ On First Looking into Chapman’s Homer, and I read the Wikipedia page. (The poem appears there, too.)
Despite what it says in the poem, it wasn’t “stout Cortez” who stood “Silent upon a peak in Darien”, but Nuñez de Balboa. But although the error was identified, apparently
“Keats chose to leave it in, presumably because historical accuracy would have necessitated an unwanted extra syllable in the line.”
