Old handwriting is hard to read. Crypto-people often find deciphering a ciphertext is easier than reading its decipherment.
Now, I added my decipherment of an enciphered passage from a letter from French ambassador Vivonne to King Henry III dated 17 September 1586 (BnF fr.16045, f.244) in "French ciphers during the Reign of Henry III of France". The letter is printed in a scholarly article, but the transcription of the ciphertext from the decipherment in the margin is incomplete. My decipherment from the ciphertext complements the reading (albeit yet not complete).
By the way, I'm glad to find that my transcription of cipher symbols can be used to read actual ciphertext.
