Cribs in the Voynich MS

[Koen G]

The second one is one I proposed myself some two decades ago by now.
f67r2 shows a circle split into twelve segments. There is a good chance that these represent the twelve zodiac signs.
The second ring from the outside has short pieces of text covering 3-4 lines each.
In seven of 12 segments there is one word standing apart a bit.
There is a good chance that these are the seven planets ruling this zodiac sign.

I somehow missed this part so far, this is very interesting indeed. The 7 words do stand out. But aren't all signs supposed to be ruled by a planet? Why single out 7? If 5 of the labels were repeated, this would absolutely be a clear case. 

Have you looked for parallels?

Edit: also, looking at other occurrences of these labels, it appears that the majority of them are unique, which is at the very least unexpected.
