Suppose there were an alternate history Earth, very much like ours, but with one difference. In this world, Shakespeare decided to pursue a career as a merchant, instead of a poet. Many phrases that Shakespeare invented never entered the language. Nobody says “hoist by your own petard”, for example.
Most creative works that reference Shakespeare still were written, but reference other works instead. The Star Trek episode The Conscience of the King was instead named Badger By Owl-Light, and the actors perform The Duchess Of Malfi, instead of Hamlet.
Other than that, everything is the same. All the events that happened in our world happened in theirs, too. History books from both worlds are identical, except for a different phrase here and there. Lists of who won or lost various sporting events are identical.
Now, suppose a copy of Shakespeare were to fall through a space warp from our world to theirs, and should by chance arrive at the desk of a great professor of literature. He reads it.
What are the chances that he would be impressed?
If he were to publish it, would the public notice, or like it?
If he were to mount a production of Hamlet, with the world’s greatest actors, the world’s greatest director, the best set and costume designers, would anyone want to see it?
