Do you know what a zodiac sign is? It is the projection of the position of planets, and the Sun and the Moon on the Ecliptic at the moment of birth. There are 12 zodiac signs, and one out of the 12, contains a bow and arrow in the constellation. This zodiac sign is called a Saggitarius. Here is how the myth goes: Sagittarius or Chiron, son of the Titan Cronos was one of the many centaurs in Greek mythology. Chiron however differed from all of the other centaurs for several reasons. One main reason was that Chiron was born half man and half horse, whereas the other centaurs were born of the sun and rain clouds. One day Chiron was accidentally shot with a poisoned arrow by Hercules. Even though he was a great physician, Chiron could not heal himself. Being immortal, Chiron could not die but was pained by the poisoned arrow. To die, Chiron offered to replace Prometheus who was punished by the gods for giving fire to man. As Chiron gave up his immortality to release Prometheus from his chains, Zeus king of the gods saw the kindness of Chiron and immortalized him in the stars.
