Mythology & History

In Greek mythology, Centaurus represents Chiron, the wisest and most just of all centaurs. Unlike other centaurs, Chiron was civilized, learned in medicine and music, and tutored heroes like Achilles, Jason, and Asclepius. When accidentally wounded by a poisoned arrow, he gave up his immortality and was placed among the stars by Zeus.
