No text, but a visual code

[Linda]

Linda, don't you think that it is contradictory to maintain that the images of de Voynich are symbolic and those of the Tratado de Astrologia are a simple embellishment?

No, not really. I see the vms imagery as visual mnemonics, the Tratado imagery as decoration. I don't see anything in the Tratado designs that would make me think it refers to the tables or illustrations they surround. With the vms since we cannot read the text it is hard to say whether they go together but i will assume that they do, however i cannot see the vms imagery as simply decoration of the text since i see cohesive meaning in it without the text support. It may well stand alone. If you took the scientific parts away from the Tratado, i don't think it would be anything but pretty.

In the Tratado we see this illustration: a castle in an astronomical diagram as in the Rosette folio

Ok so there is a castle. I assume you are attempting to equate it with the rosettes central castle. But castles are in lots of manuscripts. I do not see any interaction between the castle and the embellishments that would somehow equate them to the two superficially similar icons in the rosettes, other than whatever resemblance there is visually. Not sure what is going on with the page, can you explain what you think is going on here? What is this meant to symbolize and what does it stand for in relation to that quarter and with the scale numbers? I tend to doubt it has anything to do with either of the castles in the rosettes, but i would need to understand the page better to be able to speak directly to that. The drawing style is certainly different.

And we also see this image

Two tubes coming out of the star-studded celestial globe. They are the same tubes that we see in the Rosette folio.

In how many manuscripts have you seen those heavenly tubes?

I don't catalog heavenly tubes since i think the tubes in the vms are more earthly in nature, so i don't know if i have seen any manuscripts of that ilk. But with regard to this example, i see them as a spit on which the heavens turn, not tubes, per se, in this instance. Nothing is meant to go through them. This diagram i think i understand. The tubes in question mark the first points of Libra and Aries respectively, where the celestial equator crosses the ecliptic. The latter defines the ecliptic coordinate of 0,0 and is considered the prime meridian from which right ascension is calculated. If i wanted to show the glyphs are not text but some sort of astral coordinates, i would work more along those lines than regarding those points as heavenly tubes. So we disagree.
