New Atlantis as Myth

We have discussed several times how Bacon's view of myth goes back and forth.  We haven't discerned whether or not he wants us to study myth as a testimony of truths that people knew when they lived closer to nature or whether Bacon doesn't take myths seriously after all.

Given that Bacon is constantly reminding us how much work he has to do in so little time and how important it is to him that we read as much of his work as is possible before he dies, I wonder if Bacon wrote "The New Atlantis" as a contemporary myth that we the interpreters may study just as Bacon studied the Greek myths.  If so, why was it so important to him to write a myth instead of an analytic or technical piece like "Preparative?"  Is it because he does believe in the power of myth in scientific study?
