Regarding the provenance of the 'Leipzig' pattern for the cosmos, there is a bit of interesting information in the article in Post #54. In Fig. 2 there are three cosmic diagrams, from early printings of Sacrobosco's text. They are [Date, Publisher, Location] from left to right: 1) 1485, Ratdolt, Venice; 2) 1488, Santritter, Venice; and 3) 1488, Landsberg, Leipzig.
While the interior artwork on the four elements differs in detail, the two Venetian examples are quite similar while the Leipzig diagram is quite different, as is noted in the paragraph below the illustrations. Both Venetian diagrams represent the planets with their astrological signs arranged in a vertical stack. Both are encircled by an outer ring with the astrological signs of the zodiac. The 1488 Leipzig diagram is much different, Instead of astrological signs for the planets, each sphere is named for its planet. There is also a moon, a sun and five stars to represent the occupant of each of the spheres. There is no circle of zodiac signs. And the central earth is now a blank circle with two words indicating it as the "sphere of elements".
The diagram 1488, Landsberg, Leipzig has no astrological or zodiac symbols. Both the planetary symbols and the pictorial representation of the Earth's four elements have been converted to linguistic designations. A similar example of a code shift appears in the investigation of the VMs cosmos.
Now compare 1488, Landsberg, Leipzig with the diagram 1494, Landsberg, Leipzig from Post #6. The new diagram retains the linguistic elements from the earlier illustration, and it adds an outer ring of zodiac symbols. Even more, each of the planets is found in its sphere represented by its astrological symbol and most of these are located in the respective area of their primary zodiac sign. And they are arranged to give the 4-1-1-1 pattern relevant to VMs investigation.
Somewhere between 1488 and 1494, this significant development took place. From the article, it appears this could be due to the influences of Wenzel Faber. Could it be that the 'creation and composition' of the VMs is closer to 1500 than it is to 1450??
