"Codes, Ciphers, and Secret Languages" by Fred B. Wrixon

Perfect for word lovers and puzzlers, this comprehensive, illustrated volume includes Indian sign language, Morse code, Jefferson's cipher wheel and more, presented in an informative and historical manner.

Advances in cryptology were definitely hindered by its close association with mysticism. In the presence of the expansion of religion, especially Catholicism, secret writing was at first banned, and then outlawed in many places.
Presents Indian sign language, Morse code, Jefferson's cipher wheel and other European and American codes and ciphers from ancient times to the present, in their historical context
