The headdresses the women in the Voynich manuscript wear tell us plainly that they gathered from different areas in Europe. We know from history and genetics that Finno-Ugric peoples underwent series of migrations west.
Note that throughout all of these posts, we are still within the circled area that presents the most likely region from which the Voynich originated.
Here is a comparison of buildings in the Voynich manuscript with those found mostly around Prague, Czech Republic and accompanying waterways. For example:
Schwerin Palace gains access to the Elbe. (The map above shows this castle as Hluboka. This is an earlier, incorrect assumption.) The journey is on the whole linear but within each rosette it is non-linear, the castles acting as centers of a funnel to tributaries into the main waterways--rendezvous places for the journey.
Blatna Water Castle: the Lomnice.
Karlstejn: the Berounka.
Kokorin: also the Elbe.
Pardubice/Hrad Kunětická Hor: Elbe to Vltava (Moldau) to Danube
|A. Schwerin Palace*|
|E. Kokorin Castle|
Correction: A. is not the State Chateau of Hluboká pictured above , as previously posted,
but rather Schwerin Palace pictured at the top of the post.
