It is general but based on three works - one other MS
from the turn of the 15th/16th c. which shows the _figurae_
by themselves (ie. without circles or spheres) and
an inclunabul printed in 1488 which shows the _figurae_
each in the centre of the square horocopic diagram
giving the boundaries of the houses but no planets
(and - as you said - with the degree for which the _figura_
is represented being on the ascendent). Above is a short
divinatory phrase. But nothing VMS-like.

Yes, it is the same (the book has all of them but
the remaining ones are in not-too-good b/w reproductions).

Well, I would argue that this scheme was as unchanging
as the Zodiac itself - ie. it was equally "tropical".
The proof is the fact that all the sources quoted above,
which differ by over 200 years, as well as some even earlier
sources quoted in the book (Peter of Abano), assign the same
_figurae_ to the same degrees of the (tropical) Zodiac.
Thus they were moving away from the original constellations
to which they refered and cannot be used to date the work
where they appear - just the rough date when the system 
was "frozen".

Best regards,
