Ciphers from Louis XIII's time

I uploaded a new article: "French Ciphers during the Reign of Louis XIII".
I pointed out in 2019 that code elements with figures with diacritics used early in the reign of Louis XIV (1661, 1675, 1676) had already been in use during Henry IV's time. Most of the specimens of ciphers from Louis III's time presented in the present article follow this pattern.
