Here’s something a bit unexpected: a teen novel built around school rivalries, DNA testing, the Voynich Manuscript and the Phaistos Disc. Due to come out in February 2010, could “That’s Life, Samara Brooks” be the first properly crossover Voynich-themed book to add to the Cipher Mysteries Big Fat List? I’ll be sure to get a copy along the way… and will let you know. 🙂

Incidentally, Google Books also returns a hit for “Voynich” in Frank Portman’s (2009) similarly-genred children’s book “Andromeda Klein“, but I suspect that the VMs will turn out to be less central to the plot there. Just in case there are any completist Voynich teen novel collectors out there. 🙂

Next Sunday (8th November 2009), $99 should get you into a one-day mini-conference in LA focusing on “hidden history, signs, symbols, and secrets”, hosted by Simon Cox, author of the brand new book “Decoding The Lost Symbol”…

OK, I’m sure you’ve rumbled the secret already: that it’s basically a one-day press launch for Simon Cox’s book, with a load of sort-of-relevant speakers doing their thing (and not a cipher mystery in sight, as far as I could see). I’m sure there are plenty of people who would enjoy this, but I personally won’t be red-eyeing over to the West Coast for this. (But please leave a comment here if you do happen to go.)

All of which does raise the question of whether I should organize my own proper cipher mysteries / secret histories conference (not to promote a book, but just to have some fun) and where. After all, there are plenty of nicely evocative places in Ye Quainte Olde Londonne Towne that I could hire for the day at less than staggering expense, and finding places to put speakers up should be straightforward. The kind of stuff I’d expect it to cover should come as no big surprise:-

  • The Voynich Manuscript
  • The Rohonc Codex
  • John Dee’s secret history (a perennial favourite!)
  • Rosicrucianism and Alchemy
  • Historical code-breaking – a practical guide
  • Armchair treasure-hunting / Treasure maps / The greatest (real) treasures never found
  • Panel: “Renaissance Symbolism – True or False?”
  • The Secret History of Renaissance Astrology
  • The Phaistos Disc (possibly)
  • (…and so on)

Would that be your idea of a perfect day out? Feel free to tell me what’s missing from the agenda!

I’m getting a bit cheesed off with the Internet: every time I do a search for anything Cipher Mysteries-ish, it seems that half Google’s hits are for ghastly sites listing “Top 10 Unsolved Mysteries” or “10 Most Bizarre Uncracked Codes“. Still, perhaps I should be more grateful to the GooglePlex that I’m not getting “Top 10 Paris Hilton Modesty Tips” and its tawdry ilk.

Realistically, there is only one uncracked code/cipher listing on the web from which all the rest get cut-and-pasted: Elonka’s list of famous unsolved codes and ciphers. But Elonka Dunin has long since moved on (coincidentally, she went from cryptography into computer game production at about the same time that I made the reverse journey), which is perhaps why all of these lists look a bit dated. Perhaps I should do my own list soon (maybe, if I had the time).

Happily, Elonka did manage to nail most of the usual suspects: the Beale Papers, the Voynich Manuscript, Dorabella, Zodiac Killer, d’Agapeyeff, Phaistos Disk, and so on… each typically a piece of ciphertext which we would like to decipher in order to crack a historical mystery. However, one of the items on her list stands out as something of an exception.

For John F. Byrne’s 1918 “Chaocipher”, we have a description of his device (the prototype fitted in a cigar box, and allegedly contained two wheels with scrambled letters), and a fair few examples of both Chaocipher ciphertext and the matching plaintext. So, the mystery isn’t so much a whodunnit as a howdunnit. Though a small number of people are in on the secret mechanism (Lou Kruh, for one), Byrne himself is long dead: and the details of how his box of tricks worked have never been released into the public domain.

Was Byrne’s Chaocipher truly as unbreakable as he believed, or was it no more than the grand delusion of an inspired cryptographic outsider? This, really, is the mystery here – the everything-or-nothing “hero-or-zero” dramatic tension that makes it a good story. Yet hardly anybody knows about it: whereas “Voynich” gets 242,000 hits, “Chaocipher” only merits 546 hits (i.e. 0.0022% as much).

Well, now you know as well: and if you want to know a little more about its cryptography, I’ve added a Chaocipher page here. But the real site to go to is Moshe Rubin’s “The Chaocipher Clearing House“, which is so new that even Google hasn’t yet found it (Moshe emailed me to tell me about it, thanks!) Exemplary, fascinating, splendid – highly recommended. 🙂

OK, enough of the raw factuality, time for the obligatory historical riff. 🙂

I’m struck by the parallels between John Byrne’s device and Leon Battista Alberti’s cipher wheel. Both men seem to have caught the leading edge of a wave and tried to harness its power for cryptography, and made high-falutin’ claims as to their respective cipher systems’ unbreakability: whereas Alberti’s wave was mathematical abstraction, Byrne’s wave was (very probably) algorithmic computing.

Circa 1920, this was very much in the air: when J. Lyons & Co. hired the mathematician J.R.M. Simmons in 1923, the company was thinking about machines, systems, and operational management: mathematical calculators were absolutely de rigeur for them. The first Enigma machines were constructed in the early 1920s (and used in a commercial environment), and there were doubtless many other broadly similar machines being invented at the same time.

Do I think that there was anything unbreakable in Byrne’s box? No, not really: the real magic in there was most likely a programmatic mindset that was cutting-edge in 1918, but might well look somewhat simplistic nearly a century later. But I could be wrong! 😉

A few days ago, chess-playing crypto guy Tony Gaffney emailed Cipher Mysteries about “The Subtelty Of Witches” in the British Library: I also blogged about his attempted solution to the Dorabella Cipher and the (not-very-)Ancient Cryptography forum where he often posts on historical ciphers. Since then, the copy of his 2005 book “The Agony Column Codes & Ciphers” (which he wrote under the byline “Jean Palmer”) I ordered has arrived… but is it any good?

(Incidentally, “agony columns”  in Victorian newspapers were originally for readers to post personal announcements and messages about/for missing friends and relatives: while “advice columns” (which became popular in the 1950s) were actually a continuation of an eighteenth century newspaper feature known as “letters to the lovelorn“, as well as the advice column in popular magazine “The Lady’s Monthly Museum”. All of which means that the phrase “agony aunt” is a kind of uneasy linguistic marriage between two quite different types of newspaper column.)

People liked the ability to leave messages in agony columns: but some,  wishing to remain anonymous, submitted their messages in code, in cipher, or in some other cryptic manner. Tony’s book collects together 1000 of these (simultaneously public and private) messages.

On the one hand, I can well appreciate the compositional agony of transcribing so many ciphertexts (which themselves may well have been scrambled by harried typesetters) and then trying to decipher them (which may not always be possible). I can also appreciate that a collection of these could well offer a nice commuter alternative to the sheer maddening pointlessness of Sudoku (oh look, all the numbers add up… and here’s my station).

On the other hand, who (apart from cipher history junkies such as me) would really connect with the content of such a project? Stripped of background, context, and outcome, the results are – if you go through your own agony of deciphering them – typically no more than fleeting half-scenes from lost Victorian soap operas, full of thwarted & hopeful love and clandestine meetings.

Structurally, the book comprises a series of dated cipher fragments sorted into chapters according to the newspaper in which they appeared (The Times, The Morning Chronicle/Observer, etc) and sorted by date, with a cipher key listed at the end for most (but not all) of the enciphered ones. All very logical and sequential as a reference work: but does it really work as a piece of cipher solving entertainment?

With my historical cryptography hat on, I’d say yes: the reader is presented with a cleaned up set of cipher transcriptions, with exactly as much information as a curious newspaper reader of the day would have had. It’s straightforward and clear, a nice little slice of cipher history.

But with my publisher hat on, I’d say no: as an editor, I would have discarded the merely cryptic, and rearranged the same material as a series of enciphered threads graded by difficulty, so that a commuter could engage with it as if it were a cipher puzzle-book. I’d also have opted for a larger page size, and included pre-printed solving grids and a sorted frequency count for all monoalphabetic ciphers.

(A fine example of this kind of cipher puzzle book is Elonka Dunin’s (2006) “The Mammoth Book of Secret Codes and Cryptograms”, which also briefly describes the Voynich Manuscript on pp. 489-493, as well as the Beale Papers, the Dorabella Cipher, the Zodiac Ciphers, and the Phaistos Disk).

I would also have moved all the (currently) unsolved ciphers to an end chapter, together with brief failed solving notes.

On balance, then, I’d say that the cipher historian side of me enjoyed the book, but the cipher puzzler side of me felt frustrated by its structure. However, because I would guess that cipher puzzlers outnumber cipher historians 100:1, perhaps it might be an idea for Tony to revisit this project, to Elonka-ify it?

The Voynich Manuscript belongs to an elite club of mysterious and as-yet-unread historical artefacts. But might this club be about to lose a member?

An article in the July-August 2008 edition of the archaeology journal Minerva (as reported by the Times) declares that the Phaistos Disc may well be a hoax. Having already debunked a number of questionable artefacts in the past, Jerome Eisenberg is well-placed to spot fakes: he now suggests that the Italian archaeologist Luigi Pernier did not discover it in 1908 in the Minoan palace of Phaistos on Crete, so much as plant it there, to try to keep up with the stream of Cretan discoveries being made at the time by Sir Arthur Evans and Federico Halbherr.

As evidence for a hoax, Eisenberg points to the (implausibly) perfect uniformity of the “pancake” with its (implausibly) cleanly cut edge, together with the (implausible) movable-type-style stamping.

As evidence against, other people point to similarities between the Phaistos Disc and the marks on the Arkalochori Axe, as well as the subtle similarities between Phaistosese and Linear A.

It’s a Gordian knot, one which only a sharpened knife can untie satisfactorily: best of all would be a non-destructive thermoluminescence test, to determine when the object was fired – and if it was fired circa 1908, that would be the end of that.

What do I think? Having been to Crete for my own close look at the Phaistos Disc in the museum (and yes, I bought a reproduction home, it’s a bit touristy but what the hey), I have to say I’m far from convinced it’s a hoax. What particularly intrigued me was the place where the reproduction and the original differed – around the rim. You see, if you look really closely at the rim, you can see traces of marks that appear to have been worn away – yet (as far as I know) these marks have not been transcribed or reproduced anywhere.

At the time, this seemed to me to be the topmost portion of an entire iceberg of detail. In the same way that you can often learn more from the marginalia than the text, here I suspect that you can learn more about the Phaistos Disc from its rim than from its stamped letters. What seem to be unique features may well turn out to be improvised solutions to problems specific to the particular function that the disc performed. But that’s another story!

For more discussion (including some comments from Jerome Eisenberg himself), there’s a useful page here. You might also be interested to see this wonderful page full of (mostly) mad Phaistos Disc / Phaistos Disk theories, which rather puts my list of Voynich theories to shame. Oh well!

For a while, I’ve been wondering about what “the new Kahn” (i.e. what the updated, 2007 equivalent of David Kahn’s “The Codebreakers) would be. On a whim, I recently bought a couple of plausible-looking cryptography history books, just in case one of them might be that book…

Codes, Ciphers, Secrets and Cryptic Communication” by Fred B. Wrixon is quite cool. In its 704 pages of cryptographic and cryptologic fun, it bounces along at a fair old rate, not only discussing plenty of different historical ciphers but also describing ways of cracking them – both making and breaking. It has two brief pages on the VMs (pp.555-556). Its weakness (in my opinion) is that it is somewhat fragmented (in an encyclopaedic kind of way), possibly because it was formed by merging two earlier books by the same author into a single larger book. Good if you want a quicky book to tell you how to break historical ciphers. But not Kahn.

Codebreaker: The history of secret communication” by Stephen Pincock and Mark Frary is OK, but didn’t really work for me. Consistently misspelling Trithemius as Trimethius (even in the index) didn’t help in this regard: but the book has other merits, such as the glorious colour photograph of the Phaistos disk on page 5. It’s a well-illustrated piece of popular science journalism, with three colourful pages on the VMs (pp.49-51, showing f11r, f56r, and f67r1-2, though labelling them “Nature and alchemy” might be a little be off the mark). Random House obviously thought there was a need (in these post-Da Vinci Code days) for a colourful cryptography / history / journalism thing: I’m not so sure. I suspect the authors would have been better off telling a historical story than what they produced: beautifully produced, but not really enough of any substance, nor large enough to be a proper coffee table book. (Sorry!)

Which leads me back to David Kahn. If you are serious about reading up on the history of cryptography, I’d suggest searching on BookFinder.com for a copy of the unabridged (1136 page!) version of “The Codebreakers”. For now, Kahn is still king! 😮
