[split] Diplomatic ciphers

[MarcoP]

MarcoP & JKP:

I can share with you my complete scans of the 2 volumes of "La diplomazia sforzesca nella seconda metà del Quattrocento e i suoi cifrari segreti" by Lydia Cerioni

I can give you links where you can download

"Die Anfänge der modernen diplomatischen Geheimschrift. Beiträge zur Geschichte der italienischen Kryptographie des XV. Jahrhunderts" by Aloys Meister

and

"Die Geheimschrift im Dienste der Päpstlichen Kurie von Ihren Anfängen bis zum Ende des XVI. Jahrhunderts" by Aloys Meister

I have more ontop of that, of course, but that is a pretty good place to start with diplomatic ciphers of the time.

Thank you, Mark!
At the moment I don't intend to start with diplomatic ciphers: nothing as serious as that. I am just curious to see actual XV century ciphered texts. I can't read German, but I browsed through "Die Anfänge..." and I didn't see any actual ciphered texts (but I might have missed them). 

In You are not allowed to view links. Register or Login to view. I have just found this example, which is already closer to what I am interested in (but much too short and too simple).
   

I would like to see scans of manuscripts that use one of those ciphers in which a single plain-text symbol is mapped into multiple cipher-symbols. I am curious to see how scribes handled the different options. If you can point out to specific pages in Meister's books with examples of this kind that you found interesting, I will check them out.

If Cerioni's books reproduce actual ciphered documents and you feel like sharing them, her Italian certainly is more accessible to me than German Thank you, again! 

Since I don't intend to actually study the whole books, if it's more convenient for you, you could just share a few pages here.
