Voynich Authorship

[Mark Knowles]

In the VMS Rosettes, the castle walls have swallowtail merlons, while in the Barbavara insignia above, the merlons are square.

Yes, that's true, but I don't think the swallowtail merlons on the Rosettes page represent the Barbavara insignia. I think they represent the Castello di Porta Giovia and the Murata in Bellinzona(between top left and centre left rosettes) respectively. As a side note there are swallowtail merlons now at the Abbey of Saints Nazarro and Celso where Antonio Barbavara was Abbot.
