A Treatise On The Art Of Deciphering, And Of Writing In Cypher: With An Harmonic Alphabet is a book written by Philip Thicknesse and published in 1772. The book is focused on the art of secret writing and decoding messages, commonly known as cryptography. It provides a comprehensive guide to creating and breaking codes, as well as an introduction to an innovative harmonic alphabet system. The harmonic alphabet is a unique method of encoding messages that uses musical notes to represent letters, making it difficult for unauthorized parties to decipher the message. The book also includes examples of different types of ciphers and codes, and provides practical advice on how to create and use them effectively. This book is a valuable resource for anyone interested in cryptography, secret writing, or the history of communication technology.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
