Antonio Francesco Gori

[ReneZ]

Undoubtedly from someone's theory published somewhere in the depths of the internet.

It reminds me of one theory by Diane O'Donovan, related to an Italian book dealer, but that was a different name, which doesn't spring to mind right now.
It will probably come just after I hit 'Post Reply', in which case I will edit this post.

Edit:
the person's name I could not think of just before is Guglielmo Libri.
