Zodiac Construction

[Koen G]

If you imagine all the nymphs lined up in a single line (or circle, if you want a cycle), then it makes sense to read from the inner circles to the outer ones. 

• In Pisces, the inner circle is unique with horizontal barrels
  
• The outer circle of Pisces and the entirety of both Aries maintain figures sitting in patterned barrels.
  
• In the first Taurus, the only really elaborate barrel is on the inner ring.
  
• Second Taurus switches to walking nymphs in the outer ring.
  
• Gemini is a bit weird: there are nymphs standing on stuff in the bottom left outer ring, as well as one in the top row.
  
• Cancer to Sagittarius is plain nymphs all the way through.
  
• BUT in the top (third ring) row of Sagittarius, something like one or two horizontal tubes can be observed. A transition to something in the missing pages, which evolves to the horizontal barrels of Pisces inner ring? (Pure speculation).
  

No idea where the rings should start. Clockwise reading seems suggested by preferential walking direction.
