Photocopies of Ciphers of Captain Moise Ceffis of Venice. [n.d.]
(8 pages, 20 in. x 7 in.)
Scope: Photocopies of Ciphers of Captain Moise Ceffis of Venice so that the secret matters of Princes and Potentates may be
readily written and easy to be deciphered but easy only to the person to
whom the letter is sent and it would be impossible for the teacher of
this cipher to decipher that which can be written with the rules of this
cipher. The cipher is based on crosses with which an infinite number of ciphers
by changing the number of the square, writing always in this
form.
