A sonification of the stellar catalogue compiled by Greek astronomer Hipparchus of Nicaea in the second century BCE. His work, based on even more ancient observations from Assyro-Babylonian astronomers, was handed down three hundred years later by Ptolemy, in his second-century treatise known as the Almagest, 'The Greatest'.
Hipparchus's catalogue was compiled with naked-eye observations and the few instruments available at the time (gnomons, astrolabes, and armillary spheres). It lists the positions of 850 stars with a precision of less than one degree.
