The illustrations are probably copied from a Late Antique version of Germanicus' treatise; the subjects modeled in a "lively, illusionistic" manner typical of ancient painting. The missing constellations, Virgo Centaurus with Lupus and Corona Australis can be found in a different tenth-century copy of the Leiden Aratea located in the municipal library of Boulogne-ser-Mer. After the thirty six images of the constellations, there are two images which represent the five known planets at the time. Four male heads and one female head that are detached represent these five planets and they are described as "wandering stars" that "follow a different law." The five planets are Saturn, Mercury, Venus, Jupiter, and Mars. On a different page, four female heads represent the four changing seasons.
