This looks in style similar to the picture "horse-riding boy with planets" ...
Both objects are addressed with "illustration d'un traité d'astrologie"
I could imagine, that both pictures are from the same source.
Added: Maybe it's just a general style in German astrology books.
Re: The Sun
92The same picture with colors . The bottom line Nationale de France Allemande points to a German origin.
This has something to do with it, but I get no content.
