The Voynich manuscript, now MS 408 of the Beinecke library at Yale University, appears
to be a late mediaeval scientific compendium written in an unknown cipher script. It has been
dated to the fifteenth or sixteenth centuries by experienced palaeographers.
Most cipher texts of this period have easily yielded to modern cryptanalysis,
but this one has defied experts for nearly 100 years.
This is a page where I post occasional thoughts on the problem.
It is not intended as an introduction to the subject but as a noticeboard for interested
parties.
I am not myself a cryptanalyst, but my doctoral thesis concerned mediaeval German and Latin and I have a fair idea of what a convincing solution should look like. I have also worked in computational linguistics. My observations on the Voynich manuscript focus on the 'biological' section, ff. 78r to 84v, because it is a self-contained piece of text thought to represent the work of a single scribe in a single one of the two apparent languages of the manuscript. I make use of existing work by other researchers and of the transcriptions made available by the admirable European Voynich Manuscript Transcription project, to all of whom thanks and credit are due. Occasional criticisms of views I do not share is not intended as disrespect for their authors. For comprehensive information on the manuscript, follow the links at the foot of this page.
