In a way, MaryAnn.

But on the other hand-- I'm no historian, but I believe the equivalents of The New Criterion (let's say, those who considered themselves defenders of old, solidly traditional values) loathed Keats, treated him as a practitioner of "cockney poetry," a somewhat ludicrous follower of the leftist overturner Leigh Hunt. Shakespeare was an "upstart" practicing a low, vulgar art form, not a darling of learned reactionaries. And Milton was a revolutionary.

None of those three writers set out to make poems entirely in an old manner or according to old rules.

And though I make many mistakes, I believe that all three could get a sonnet published in Slate.

(Along with competent young writers in pentameter and rhyme (sometimes) like Mr. Campion, or Gunn and Walcott before him.)
