I have read Pratt's book. JB Porter is certainly J. B. Porta,
Ioan. Baptista Porta, Giovanni Baptista Porta, della Porta, etc.
His book, De furtivis literarum notis, was published in 1563 in
Naples, and again, under the title De occultis literarum notis in
1590 and 1603. See Kahn for a discussion of Porta's place in the
history of cryptography and Galland for a discussion of the various
(many) editions. I don't know of an English translation, but one
might think of Wilkin's Mercury of the Secret and Swift Messenger
(1680 or so, London) as a kind of near-contemporary rephrasing of
Porta's book.

There was a facsimile reprint edition of the 1593 Montbeliard
edition privately printed in 1996, handed out as a party favor
at the 1996 Eurocrypt conference in Zaragoza
