Voynich is encrypted ENOCH

[Radim Dobeš]

Supports the Ethiopian trace in the VM

It is possible, of course, that the Scribe who drew the VMS pictures was drawing "inspiration" from an Ethiopian book, among all the other books that we have identified as highly probable sources of "inspiration".  

But another possibility is that both the VMS artist and that Ethiopian artist drew inspiration from the same source book, possibly through multiple copying steps.  

Can we find other books, preferably European, with that same sort of imagery: ladies in tubs up to the waist, with decoration on the tubs that resembles columns and arches?

connection with the Book of Enoch

Yes, this icon and its theological background contain a strong symbolism connected with the coming of the Chosen One (Messiah/Christ). Orthodox iconography never depicts historical events in isolation, but always connects them with the prophecy of the coming of the Savior.
One of the main motifs of the Book of Enoch is the coming of the Chosen One.
The author of VMS hid the baby Jesus behind the edge of the container.
