Pair of planetaria
A different way of representing the alternative planetary systems from the armillary spheres on the top shelf. On the left is the Ptolemaic system, on the right the Copernican, and viewing them from above would have been a particularly effective way of comparing the two. The planets are represented by symbols mounted on the appropriate rings.
