I do not recall if it has previously been noted, but for the
record there are two suns that appear in the corners of the 9-rosette
(f85/f86) foldout folios, one in the top left corner and one in the bottom
right hand corner. Only a few remnants of the sun drawn in the bottom
right hand corner appear in the Copyflo.
(Thanks to Petr Kazil for these online references)
Top left (North West): (shown here "upside down" in reference to Copyflo,
at the bottom right corner in this URL)
Bottom right (South East): (also shown here upside down at top left
corner)
At the bottom left and top right corners are the spherical objects
(clock?) 'contrived' by human hands.
Other volvelles that may be of interest:
