One more thing about John Keats

Nathaniel Hawthorne (who looks so much like Brother Enward in this famous picture) wrote a short story in 1845, called "P.'s Correspondence" which was one of the earliest works of alternative history. The story was about what Keats later life would have been like, and what poetry he would have written, had he not died so young.

I haven't read it, but it's on my list.
