It belongs to
Cleomedes' Lectures on Astronomy (or Caelestia).
The Lunar Reconnaisance Orbiter provides this view of
Cleomedes Crater.
See, e.g., the episode recalled in Pausanias 6.9.6-8 about
Cleomedes of Astypalaea, who disappeared while seeking refuge from an angry mob in the sanctuary of Athena: "He entered a chest standing in the sanctuary and drew down the lid.
The closest be comes to answering it is the description of
Cleomedes, the fifth-century Olympic victor who miraculously escaped from a closed chest: "It is perhaps because of the exceptional nature of
Cleomedes' disappearance that he is the only one of these fabled athletes to be unambiguously called a hero" (41).
But, in its overall features the evidence suggests that Posidonius and
Cleomedes differed from their Stoic precursors on this topic.
As the astronomer
Cleomedes put it in the second century AD, `Nature likes life, and reason proves that wherever conditions allow it, earth should be inhabited by living beings'.
Between Macrobius and
Cleomedes, and continuing on toward the limb, there is a less-regular boundary with dark mare lava near the Wasatch Mountains.
Other dark halos are found in Petavius and
Cleomedes, though those in the latter crater are tiny and very difficult to detect.
