Was Hartmann Schedel in possession of the VMS? I think so.

[Jorge_Stolfi]

The problem is the regional differences in spelling, which leads directly to a deep exegesis in every attempt at deciphering if you apply Voynich as a simple cipher in Bavarian.

I am not surprised.  It is a more specific version of the same fundamental mistake every expert makes when attacking the VMS.  "The drawings look {European|Bavarian}, so the language must be {European|Bavarian}.  But since a simple alphabet change does not work, it must be some sophisticated cipher."

All the best, --stolfi
