Ptolemy’s 1,022 Stars

“The great quest of medieval science was for a perfect copy of Ptolemy’s Almagest, written in Egypt in 147 AD. It was known to have thirteen sections, with the most accurate analysis of star and planetary paths ever achieved, alongside a catalogue of 1,022 starts listed on a scale of magnitude from 1 to 6. It was a key that threatened to unlock the secrets of the heavens.”
