For example, Hero of Alexandria (mid-1st century ce) asserted, purely for philosophical reasons, that an object and its mirror image must make equal angles to a mirror. He also applied fundamental theorems in spherical trigonometry (apparently discovered half a century earlier by Menelaus of Alexandria) to the solution of many basic astronomical problems.
