Premise: The cosmolabe was an ancient astronomical instrument resembling the astrolabe, formerly used for measuring the angles between heavenly bodies. It is also called pantacosm. Jacques Besson also uses this name, or universal instrument, for his invention described in "Le cosmolabe" (1567), which could be used for astrometry, cartography, navigation, and surveying.
Hypothesis: Le cosmolabe was published more than 100 years ago.
