Cipher Mysteries

For a decade, I've wondered whether any of the Voynich Manuscript's circular drawings depict astronomical instruments - for before satnav there was celnav ("celestial navigation"). Here's a brief guide to three key instrument types from the VMs' timeframe, and my current thoughts on the enigmatic circular diagram on f57v... * * * * * * * A key navigational problem of the 15th ...

Following a trail of breadcrumbs from my recent post on Johann Adam Schall von Bell, I'm returning to the issue of whether the VMs could ever have had a Far Eastern origin. To recap, Jacques Guy originally proposed Chinese as a kind of linguistic fou-merde joke on the Voynich research community, only to be unhappily surprised when people started ...

Once again, it's time to roll out and dust off the Cipher Mysteries crystal skull crystal ball (no, I didn't buy it on eBay, nor did I nick it from the British Museum) to peer dimly ahead to 2010. What will it bring us all? Of course, 2009's big news was the radiocarbon dating of four slivers of the Voynich Manuscript's ...

When is Easter? A simple question, but one with quite a tricky answer: following the decision of the First Council of Nicaea in 325AD, it is the first Sunday after the full moon after the Spring Equinox (which is simplified to be 21st March): hence, Easter can fall anywhere between 22nd March and 25th April. A moment's reflection should be ample to reveal what ...

Further to the recent (and much-commented-upon) post on Godefridus Aloysius Kinner's correspondence, I had a snoop around to see what other early modern correspondence roadkill I could scrape off the infobahn's oh-so-narrow historical lane. The most useful page I found was from the Warburg's Scaliger Research Project (kindly established by Professor Anthony Grafton): this contained a long-ish list ...

If you accept the basic notion that the Voynich Manuscript is both (a) very probably a genuine (if perhaps rather convoluted) cipher, and (b) mostly rational, then you run into the issue of what kind of sensible stuff lies beneath - in other words, its "secrets". All the same, how sure are we that our modern notion of "secrets" is anything like the Early Modern / ...

I just saw (via H-ITALY) an announcement for an online peer-reviewed journal from Stanford: We are delighted to announce the publication of a new digital journal, Republics of Letters. This peer-reviewed, open-access publication is dedicated to the study of knowledge, politics, and the arts, from Antiquity to the present, with an emphasis on the early-modern period. Its first issue has ...

For the recent Hungarian Voynich summer camp, I offered to do a couple of IM sessions over Skype, both of which seemed to go down very well. I thought many Cipher Mysteries readers might enjoy going over the transcript, so here it is (lightly edited for house style, as usual, and with after-the-event section dividers to make it not quite so unwieldy). ...

In a comment to a recent post on Alberti & Averlino, 'infinitii' asks what my recommendations would be for a Voynich Manuscript reading list... a deceptively hard question. Apart from the direct literature on the subject (Mary D'Imperio's "An Elegant Enigma", my "The Curse of the Voynich", and perhaps even Kennedy & Churchill's "The Voynich Manuscript"), probably the best first ...

Following on from my September 2008 article in History Today, I've just posted up an online Juan Roget bibliography listing the current set of primary, secondary, and tertiary references to Girolamo Sirtori's claim to have met the "first inventor" of the telescope in Gerona. While my article received a lot of positive attention from the Spanish media (which was nice, ...
