About Hipparchus star catalog
The Hipparchus star catalog is a list of at least 850 stars that also contained coordinates of stellar positions in the sky, based on celestial equatorial latitude and longitude. According to British classicist Thomas Heath, Hipparchus was the first to employ such a method to map the stars, at least in the West. Hipparchus is also credited with creating a celestial globe, although this object is not known to be extant. The catalog was lost to history, until parts of it were rediscovered in 2022 in the Codex Climaci Rescriptus, an ancient palimpsest found in Saint Catherine's Monastery on Mount Sinai.
