Anotations

Scope note:

Refers to maps of the heavens, including the constitution, relative positions, and motions of the heavenly bodies, which are all the bodies in the material universe outside of the Earth, as well as of the Earth itself relative to them. The earliest examples were often decorated with fantastic figures depicting the constellations and recognizable groupings of bright stars, and were primarily used as aids to navigation.
