 The inscription around the moon phase indicator says "sphericus archetypum globus hic monstrat microcosmum", which translates as "This spherical globe here shows the archetypal microcosm".Howgrave-Graham suggests that the scribe erroneously put "microcosmum", when "macrocosmum" is the more obvious word.Opposite the moon circle is a weighted pivoted disc, containing a small painting of Phoebe, representing the moon.
