if I had written a book called The Dianetics of the Hunt in Ancient Greece prior to Mr Hubbard's little experiment with the gullibility of the human race, I don't see that that title would in any way be copyrightable

If you write the book, I'll read it. But you may not get it published under that title.

How about Diana of the Hunt in Ancient Rome?
