Abstract:
Susanne M. Hoffmann reconstructed the not preserved celestial globe
(and star catalogue) of ancient Hipparchus of Nicaea digitally. She
investigated the data (celestial coordinates) on this globe and traced
their sources. By means of error analysis, visualizing, mapping, and
correlation plots she examined the potential origin of the Hipparchian
star coordinates (or some of them) in observations of earlier Greek or
Babylonian data. As preserved by Ptolemy (Almagest) and Pliny the
Elder, Hipparchus is famous for his exact observations but he does, of
course, also rely on older data - e.g. especially elaborated by
Ptolemy's discussion of precession.
Description:
Reconstruction of the lost star catalogue of Hipparchus of Nicaea (2nd
century BCE). This is the data underlaying the visualisations in the
book (2017hihi.book.....H 2017hihi.book.....H). Data given in three formats.
