Archived from the original on November 2, Views Read Edit View history. A machine translation expert, Knight approached language translation as if all languages were ciphers, effectively treating foreign words as symbols for English words.

Megyesi later realized that a particular symbol meant “eye”, and Schaefer connected that discovery to the Oculists. It is not a 1-for-1 substitution but rather a homophonic cipher: Retrieved October 25, 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 ciphrr by Pope Clement XII. The manuscript is a homophonic cipher that uses a complex substitution codeincluding symbols and letters, for its text and spaces. American Association for the Advancement of Science. 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 ciphwr, 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.

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