A match for the containers? 16th-17th century ivory vases

[JoJo_Jost]

A person who is creating a genuine work in their time mostly knows there time, their discipline, their language, has their style from their era

Yes, and a great deal has been accomplished in this regard over the past year, particularly with the VMS, partly because more and more books from that period are being digitized.

Thanks to these comparisons, it’s now becoming increasingly possible to narrow down the location where the manuscript must have been written, and we can also link specific objects to more and more books from that period that the scribe seemed to be familiar with.

I think that’s precisely one reason why it must have been written in the 15th century,  because Voynich clearly did not yet have access to these comparisons with other books or to the knowledge of that era.
