Pietro Partenio’s second cipher in the CX1 book of 1592-93 is an unusual mix of a cifra sospetta (suspicious cipher) and a cifra non sospetta (non suspicious ci-pher), that is cryptography and steganog-raphy. The cipher has some possible roots in Trithemius’s Ave Maria, Vigenère’s and Francis Bacon’s ciphers.
