When we look up at the night sky, we are often struck by the beauty of the stars that adorn the darkness. One of the most fascinating constellations that can be observed from Earth is Sagittarius
The Mythology of Sagittarius
The constellation Sagittarius is typically associated with a centaur, a half-man half-horse mythical creature from Greek mythology. The centaur in Sagittarius is commonly known as Chiron, who was a wise and knowledgeable teacher to many Greek heroes, such as Achilles and Hercules. Chiron was known as the ‘Wounded Healer’, as he was accidentally wounded by an arrow while trying to save his friend. This resulted in him becoming immortal but with constant pain. To lessen his suffering, Chiron decided to give up his immortality and trade it for the freedom of Prometheus, the god who gave fire to humans and was then punished by Zeus for it. After sacrificing himself, Chiron was taken up to the heavens and immortalized as the constellation Sagittarius.
