Virgo - Star in the hand?

[Gioynich]

Please let me know if this has been discussed before.
Can the star in Virgo's hand give us some hints?
In another thread, I presented a programmatic way to compute similarity between zodiacs.
Having a star in the hand is a pretty rare characteristic, observed in just 3 zodiacs out of the 100 I looked at:

1. Mantova Lat. 209 (1470, Lombardy, Italy)
   
2. Berlin Regimen Sanitatis Ms.germ.fol.1191 (1450-1460, Freiburg, Germany)
   
3. BNF Arabe 5036 (1436, Samarkand)
   

It's interesting how the bottom two are similar to each other (full constellation, left hand pinching the vest, etc.), despite being from very distant regions.
