In your opinion, did the writing of the VM start closer to 1412 or closer to 1440?

Why the Council of Basel and not the Council of Constance?
The years are close together. There must be a reason.

Because the Council of Constance was in Konstanz and the Council of Basel was in Basel. Basel fits neatly as the final destination in my map analysis, but Konstanz does not. Konstanz is actually marked on my map, but not as the final destination. Also the Council of Constance was from 1414 to 1418 and Abbot Antonio Barbavara was not at the Abbey of Saints Nazzaro and Celso then and too young to have been involved in the writing of the Voynich. Basically the Council of Basel fits neatly with my analysis, but the Council of Constance does not.
