The 'Chinese' Theory: For and Against

[Jorge_Stolfi]

Not to mention it is naturally quicker and easier to write in a system you have learnt and used and practised your entire life.

That is a good argument ... against all the other theories.  

Why did the Author invent a new script, instead of using Latin letters?  

If the text was a known language in a simple substitution cipher, one could say that he invented a new alphabet to make the encryption safer.  But it is not a simple substitution cipher; if it is cipher, it is one that put the NSA to shame.  Then using Latin letters instead of that original script would have not made it any easier to crack.

If the goal was to produce a fake "Bacon Cipher Manuscript" to defraud an Emperor, which would be more likely to succeed: one written in the Latin letters that Bacon used and which looked like they could be deciphered one day, or in a script never seen before, which looked like an alien language that no one would ever be able to read?  If the intention instead was to make it look like a book from "Egypt or some other Oriental parts", why would the forger blow the ruse away by drawing people with European dresses and hats, European Zodiac icons, European-looking castles, etc? 

In fact, the Chinese Origin Theory seems to be the only one that can offer a plausible explanation for why the book uses an original script, and why the script looks that way.  Namely, for the same reason that people have invented new alphabets: to make it easier to write down a language whose sounds would not easily map to the alphabet they used themselves... 

All the best, --stolfi
