I made a substantial enlargement in:
"French Ciphers during the Reign of Henry IV of France"
With the addition of about thirty reconstructed ciphers, it is like a wholly new article.
As a byproduct, I made some additions to:
"French ciphers during the Reign of Henry III of France"
and other related articles.
I still have some leads to work on, and hope to make further additions in near future.
I found the original of the cipher between Henry IV and the Landgrave of Hesse-Cassel reconstructed by Rommel in the 19th century. I found the catalogue entry "Clef du chiffre employe avec le landgrave de Hesse-Cassel" some years ago, but could not locate it in the pdf because of my poor network condition at the time.
