A Florentine Polyalphabetic Cipher from the 1480s

I learned in a paper by Marco Vito that the instruction for a Florentine cipher from the 1480s prescribes its use as a polyalphabetic cipher. This is the only actual example of a polyalphabetic cipher before 1560 (not counting the treatises by Alberti and Trithemius as actual examples).
This induced me to collect specimens of polyalphabetic ciphers known to me as a new article, "Polyalphabetic Ciphers before 1600".
