In the Ancient Greek myth, Cheiron was the wise king of the centaurs. He tutored Heracles but was later mistakenly shot with a poisoned arrow by his former pupil during a conflict with a group of drunken centaurs. Cheiron was semi-divine and could not die so he writhed in agony until Zeus took pity and placed him as Sagittarius in the stars. Sterling silver pendant on a 20 inch (50 cm).
