How many people penned the main Voynichese text?

[Jorge_Stolfi]

However, when writing in a new unfamiliar script, it's expected that the handwriting will evolve and writing habits change as the hand adapts to the script.

Indeed, and we can see the scribe's gradual evolution and learning in the style of the nymphs and diagrams along the Zodiac section.  His Voynichese handwriting too probably changed just as much with practice and age.

All the best, --stolfi
