Three-section orbs

[Mark Knowles]

Yellow cells share the same type of stars, which are not such a strong link as they are quite basic shapes.

I think it is a mistake to label the * as stars. There are clearly stars drawn on some pages, but these are not the same as the * . The word "star" suggests that they represent a celestial body i.e. a "sun" from outside the solar system. The term * or asterisk doesn't give an interpretation to them. On the Rosettes folio the * can be found in every rosette except the top left and centre right, do they represent stars in all those locations? And if you think they do, then how to you justify that interpretation in each of those instances?

Also, what precisely do mean by the word "bubble"?
