"Codes and Ciphers through The Middle Ages"...

I happened upon the following post a few days ago here, and thought I ought to reproduce it here for anyone that's interested (the cryptography history lane tends to be filled with caravans, and as a result is somewhat slow-moving). When the volume finally appears (in 2009?), I'll be just as interested in the paper on the Voynich Manuscript as the rest of it. Having said that, I'm a bit concerned that Kahn is not only misspelt but a little bit misrepresented (for instance, Kahn discusses medieval Arabic cryptology on pp.89-99) in the blurb.

Oh, and they're not interested in publishing two papers on the VMs in the same volume. Just so you know not to offer them one (like I did, *sigh*).

Call for contributions for a volume of collected essays:

Codes and Ciphers through The Middle Ages

This call is designed to expand and enhance an essay collection that is based on two panels entitled “Codes and Ciphers through The Middle Ages,” which took place at the International Congress on Medieval Studies, Kalamazoo MI, in 2006 and 2007.
It seeks to fill a major gap in the study of codes and ciphers in the medieval world. The codes and ciphers of the Middle Ages have received little or no modern scholarly attention. David Khan’s 1181-page volume _The Code-Breakers: The Comprehensive History of Secret Communication from Ancient Times to the Internet_, for example, devotes a mere thirty-four pages to the ancient and classical world, and little more than one sentence to the Middle Ages, claiming that “ciphers, of course, had been used by monks throughout the Middle Ages for scribal amusement” (106). But the construction and use of codes, ciphers, secret languages and mathematical secrets in the Middle Ages were much more than amusement: they were central to intellectual culture as modes of concealing dangerous, magical or secret information, and as a means of connecting oneself to the divine. As such, they appear in the writings of major figures ranging from Isidore of Seville to Hrabanus Maurus, Alcuin and Hildegard of Bingen. They also figure in the manuscripts of lesser known students of magic in Heidelberg, and numerous anonymous texts and manuscripts including Anglo-Saxon riddles, Old Norse literature and runes, and the computus. Clearly, codes and ciphers were a multilingual, cross-period, inter-cultural phenomenon in the Middle Ages; they warrant more scholarly attention. Given current emphases on “security,” and the proliferation of forms of encryption on the internet, fostering scholarly discussion of history of cryptography seems especially relevant to the 21st century. Current contributions address the uses of codes, ciphers, secret languages and mathematics in the writings of Hildegard, the Voynich Manuscript, Anglo-Saxon riddles, Hrabanus Maurus’ _In honorem sanctae crucis_, the Pseudo-Bedan _Propositiones_ and the _Propositiones ad Acuendos Juvenes_ attributed to Alcuin. While we welcome contributions on any aspect of codes and ciphers in any period of the Middle Ages, we are especially interested in essays that will widen the scope and increase the depth of the collection.

Please submit detailed abstracts or drafts of essays (style: CMS 14th edition) by 1 July 2008 to: Sharon M. Rowley at srowley@cnu.edu or rowley_sharon@hotmail.com

And the new Kahn is... Kahn?

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! :-o
