No text, but a visual code

[Antonio García Jiménez]

I doubt that in the Middle Ages it was known that twinkling is atmospheric disturbance. Putting that modern concept on a medieval man is an anachronism.
  Yes, in very certain circumstances Venus can also twinkle, but claiming that reminds me of the Spanish saying looking for the three feet to the cat, which has no English translation. It is something like to split hairs.

Now seriously, I am quite convinced that the Rosette folio is a representation of the Ptolemaic universe, with the spheres and the stars emitting their virtues on the Earth. It is an iconographic reading that is coherent with the whole book, which forms a unit.

If someone has a better unified theory and defends it with solid arguments, I might change my mind. I am a librarian at the Nacional Libray of Spain, where bibliographic treasures are kept. I believe that the Voynich is a great treasure of human culture and trying to understand it is the only thing that matters.
