Centaurus is one of the brightest of the southern constellations. There are actually two centaurs in this constellation, Chiron and Pholus. These mythical half man half horse lived in the southern Peloponnesus. Hercules journeyed through their area and spent time with Pholus. Over dinner, Hercules opened a cask of wine which belonged to all the centaurs. Pholus tried to warn Hercules, but when the cask was opened, all centaurs stormed in and Hercules had to defend himself. Hercules fought the Centaurs who eventually fled to cower at the feet of the immortal Chiron. During the battle, Chiron was accidently hit with one of Hercules arrows. Hercules was devastated at this because Chiron was his former teacher. Chiron's wound would not heal, but he could not die. Chiron was in agony and finally Prometheus felt sorry for the centaur and took his immortality. Chiron died and was placed in the sky. Pholus was also killed accidentally when he dropped one of Hercules poisoned arrow shafts on himself. Pholus too was placed in the sky with Chiron.
