Cryptographists just deciphered one of the famous indecipherable texts of the 18th century. Kevin Knight of USC Viterbi School of Engineering, Beáta Megyesi and Christiane Schäfer of University of Uppsala and others did the job – with science! Excellent coverage, pictures and excerpts courtesy of the University, also Golem.de.
The “Copiale Cipher” is a 105 pages manuscript containing all in all around 75 000 characters. Beautifully bound in green and gold brocade paper, written on high quality paper with two different watermarks, the manuscript can be dated back to 1760-1780. Apart from what is obviously an owner’s mark (“Philipp 1866”) and a note in the end of the last page (“Copiales 3”), the manuscript is completely encoded. The cipher employed consists of 90 different characters, comprising all from Roman and Greek letters, to diacritics and abstract symbols. Catchwords (preview fragments) of one to three or four characters are written at the bottom of left–hand pages.
Here is the transcript (for complete transcript, click here).
Transcription, transliteration and decipherment brought to light a German text obviously related to an 18th century secret society, namely the “oculist order”. A parallel manuscript is located at the Niedersächsisches Landesarchiv, Staatsarchiv Wolfenbüttel.

This is pretty cool. Congratulations to the team! What’s next?
