"The Argument of the Frontispiece" from the fifth edition of The Anatomy of Melancholy

This is "The Argument of the Frontispiece" from the fifth edition of The Anatomy of Melancholy (1638). I obtained the image here: http://books.google.com/books?id=cPgveWnCdRcC&printsec=frontcover#v=onepage&q&f=false
(I made the image of the page less faded.)

It is a poem about the images in the frontispiece. I suspect the poem contains clues leading to the decipherment of the message revealing the true author of The Anatomy of Melancholy. If there are clues in the poem, I have not figured them out. I think I have the right overlay solution--the author is Bacon--but it would be good to have confirmation from the poem for my solution.

I should be noted that the symbols of Saturn in the frontispiece, which I used in my solution, are mentioned in the poem. The lines of the poem "Ten distinct Squares here seene apart, Are joyn'd in one by Cutters art" may be part of a clue to "join" or overlay the Saturn symbols, as I did in my solution, but I am not sure of this.
