[split] Diplomatic ciphers

[Mark Knowles]

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.
