The Voynich Manuscript

The manuscript measures 23.5 by 16.2 by 5 centimetres (9.3 by 6.4 by 2.0 in), with hundreds of vellum pages collected into eighteen quires; depending on how some of its unusual fold-out multi-part pages are counted, approximately 240 pages in total.

The top righthand corner of each recto (righthand) page has been numbered from 1 to 116, probably by one of the manuscript's later owners. From the various numbering gaps, it seems likely that in the past the manuscript had at least 272 pages, some of which were already missing when Wilfrid Voynich acquired the manuscript in 1912.
