The place names just below the moons have been laid out on a map, and the lines drawn between them create a pentagram:
The path of the solar eclipse from f67r1 has been added. It crosses over Vienna, which the pentagram’s main line (the one with 6 places) passes over.
It is also noted that two lines cross at 50N, 10E. I don’t yet know what significance this has, if any.
Here is the same overlay on a modern map: The projections are slightly different, so they don’t match exactly.
