f67v2 - Isidore of Seville

[RobGea]

Using Isidore of Sevilles' - "The cosmos and its parts" from a ""what's up" perspective to describe f67v2  seems like a fair intepretation.
There are 3 points i'd like to add.

1. Isidore makes no mention of the 4 things at the outer edge of the drawing ( theres varying voynichero ideas for these ).

2. Isidore says 2 portals for the Sun, there are 2 extra here , though by extension we could say that these are the 2 portals for the Moon. ( idk how valid that would be ).

3. Isidores definitions suck.  
    If we ditch "sky' entirely then we would have:
   Air -->              where the birds are.
   Firmament --> where the sun and moon are.
   Ether -->          where the stars are ( and it is sphere shaped ).  
      Then we can just replace 'Sky' for "Firmament" in your annotated diagram and we are done.
