No text, but a visual code

In reality, the planets do not appear to play any role in Voynich astrology. Only the Sun, the Moon, and the fixed stars.

  The clearest thing I see, as I have already mentioned, is the relationship between the groups of three lines on the small volvelle and the corresponding groups of three lines extending from the central rosette toward the rosettes on either side. To me, it is a clear allusion to movement and the passage of time.

But you claimed that the Rosettes are planets. Perhaps it would be worth naming which planet corresponds to which Rosette?
I’m not against the interpretation that Rosettes is a vivid illustration of space, not involving any computational complexity. But it would be good to try to identify the other planets...
