Yesterday, I posted up a low-resolution image of some Codice Olindo ciphertext: it appears to be a set of slightly-accessorized 8-directional arrows (and a few double-headed arrows, plus some additional shapes (punctuation?)). It struck me when I woke up this morning that – statistics aside – this might simply be a kind of arrow-based pigpen cipher, where the arrows point to the appropriate corner of the 3×3, and the accessorization indicates which 3×3 block to refer to.

Typically, modern-day code-breakers focus (if not over-focus) on the transcription and computer analyses. However, people are sometimes motivated by quite different things from pure security – the psychology is at least as important. Pigpen is easy because you can decrypt it very fast (an arrow-based pigpen would be at least as quick to read as a ‘proper’ one), and perhaps this is what Olindo Romano wanted. And it seems likely to me that he thought/thinks he’s cleverer than all the people around him (whether that’s true or not).

Of course, this is the kind of approach I have used when looking at the Voynich Manuscript, so it should come as no surprise that this is how I look at things. I wonder: if the Italian “mathematicians” who have deciphered this cipher plotted out the letters they have found on 3×3 arrow-pigpen grids, what would they find?
