Zodiac 101

[pjburkshire]

One thing I don't quite understand is why the Zodiac nymphs are arranged in tiers. Maybe also space constraints?

That is still one of the big mysteries but on at least two circles there are specific differences.  On f70v2, in the inner circle the nymphs are not in the baskets and in the outer circle they are all in the baskets.  On f72r1, in the inner circle the nymphs are in the baskets and in the outer circle the baskets are all gone.  So, unless we are to assume that the baskets vanished then reappeared and then vanished again, I read them as going from inner circle to outer circle.

What we have is:

For about 10 days, pair nymphs and stars and place in baskets. ( f70v2 )
Let nymphs & stars sit in baskets for about 70 days.
Remove baskets.  ( f72r1 )
Nymphs & stars are ready for their adventures.  They may want to try putting their feet on grass and wearing clothes.  ( f72r2 )  They may even get a crown.
