[split] Early 15thC German Herbal & Bestiary (Augsburg, Cod. II.1.2° 109)

The mermaid's tail seems to be a match for that of the VMS:
Is the mermaid in the VMS also holding... fish?

This is a very good match too.

Yes, in VM, it seems to be a fish devouring a woman (who is strangely careless about it) so my bet was it was inspired by the Bibiblical prophet Jonah:
   

But the shape of this mermaid fits very well, even the part of fish mouth could be originally, well ... something else 
   

For me these are very strong links, comparable to Taccola!
I would risk saying that the Voynich artist saw Cod. II.1.2° 109 or its close "brother".
