Playing with 68r2

[Anton]

The fact that some stars are unlabeled in f68r2 is something worth thinking about explanations. And not only that, but it also features the "belt" of (unlabeled) stars on the circumference (which f68r1 does not).

Given that 68r1 and 68r2, judging by their similar framework, very likely present two "complementary" entities (day/night, east/west, north/south, summer/winter etc.), what would it mean that some stars are unlabeled in 68r2? One explanation is that the set of 68r2 is in a certain way "less explored", "less known" or "less developed" - such that it is known that there are objects in this set, but not all of those objects are known. In this perspective, the belt of stars may be just an embellishment introduced to stress this point. Another interesting speculation is that the total number of labeled plus unlabeled stars, belt excluded (as just the embellishment), would be essential (otherwise, why would unlabaled stars be needed elsewhere outside of the belt itself).

I once tried to match the exact numbers of objects in 68r1 and 68r2 to something known in the history of science and art, but to no avail.
