Six onion-roof towers supporting heavens

[Jorge_Stolfi]

That's nothing more than a theory, your theory.

Practically every claim about the VMS is nothing more than a theory, somebody's theory.  Basically, the only things we can treat as "facts" are the digital images and the C14 date for the vellum.

The fact is that certain things on different pages can be found on others.

Not really.  Some drawings on some pages have varying degrees of similarity to drawings on other pages.  Whether they represent the same object or concept is "nothing more than a theory".

Where? I don't see any such thing.

Distortions in astrology. Nymphs in astrology.

The same Scribe produced Cosmo, Zodiac, and Bio, in that order.  We can see the evolution of his "artistic skills".  His first nymphs were abysmally crude, but at some point after Taurus he learned to draw a passable naked woman, and used that same drawing to the end of Bio. (But of course this too is nothing more than a theory...)

it's one ‘manuscript’ in one (or two) ciphers.

That the VMS is in cipher is also nothing more than a theory. A theory born of desperation, from the nothing-more-than-a-theory that the language is "European" and the fact that the words don't look at all like "European" words...
