Oh, I forgot:

Adrian Mitchell was voted in some poll or other as the poet whose work people would most prefer to be sent out into space to represent humanity. I believe I read that in one of the obits somewhere.

I love that sonnet of Mitchell's because it's oh so poignant without being overtly blasphemous or disrespectful of the person of Jesus. I essentially tried to do much the same thing in a villanelle I posted here about Christ's crucifixion, which Don Jones and others ably realized.

Yo Don, where are ya!

You're thinking of Bishop's great "Visits to St. Elizabeths" I think, which is kind of a cumulative form, which I think was modeled after a Mother Goose rhyme that I can't think of right now. (I keep thinking Jack & The Beanstalk, but that isn't right).

As for the form, I don't know the name of either (Bishop or Mitchell) but they do seem a little bit similar.

eta: The House That Jack Built (google is my friend).
