and the last figure is especially interesting, showing the diplomatic cipher of one Francesco Tanchredino. I can't remember this discussed in the forum.
Note how:
a) the ciphertext symbols are designed: a base shape is prepended with a prefix or appended with a suffix
b) same plaintext letters can be encrypted with more that one symbol
c) plaintext letter pairs receive their own ciphertext symbols
d) some text is enciphered on a word-basis (so, partly a nomenclator solution)
