The manuscript is a homophonic cipher that uses a complex substitution codeincluding symbols copixle letters, for its text and spaces. In addition, some ciphertext characters stand for several characters or even a word. The Copiale cipher is an encrypted manuscript consisting of 75, handwritten characters filling pages in a bound volume.

The Copiale cipher

It is not a 1-for-1 substitution but rather a homophonic cipher: For example, all the unaccented Roman characters encode a space. Archived from the original on November 2, The Copiale cipher includes abstract symbols, as well as letters from Greek and most of the Roman alphabet.

The only plain text in the book is cipyer 3″ at the end and “Philipp ” on the flyleaf. His approach, which tasked an expectation-maximization algorithm with generating every possible match of foreign and English words, enabled the algorithm to figure out a few words with each pass.

The Philipp Copiales 3 document, however, appears to suggest that the Oculists, or at least Count Veltheim, were a group of Freemasons who created the Oculist society in order to pass along the Masonic rites [7] [12] which had recently been banned by Pope Clement XII. Seven ciphertext characters encode the single letter “e”. Retrieved from ” https: From Wikipedia, the free encyclopedia.

Knight then used a combination of intuition and computing techniques to decipher most of the code in a few weeks.

A machine translation expert, Knight approached language translation as if all languages were ciphers, effectively treating foreign words as symbols for English words.

Copiale cipher

Philipp is thought to have been an owner of the manuscript. The manuscript portrays, among other things, an initiation ritual in which the candidate is asked to read a blank piece of paper and, on confessing inability to do so, is given eyeglasses and asked to try again, and then again after washing the eyes with a cloth, followed by an “operation” in which a single eyebrow hair is plucked.

Previously examined by scientists at the German Academy of Sciences at Berlin in the s, the cipner was thought to date from between and A comparison with 80 languages confirmed that the original language was likely German, which the researchers had guessed based on the word “Philipp,” a German spelling.
