The Story of Sagittarius

What can the centaur Chiron teach us about the human condition?

Updated July 24, 2025 | Reviewed by Kaja Perina

In Greek mythology, after his unusual death, Zeus fixed the centaur Chiron into the firmament as the constellation Sagittarius. But who was the deeply philosophical Chiron, and why should you care about him?

Fated to be overthrown by one of his children, Cronus, the godhead of the Titans, devoured them all upon their birth. In desperation, his wife Rhea hid their sixth child, Zeus, on the island of Crete.

As Cronus searched earth and sky for Zeus, he came upon the Oceanid Philyra, after whom he lusted. To hide from Rhea, he took the form of a stallion and mounted Philyra.

In due course, Philyra gave birth, with great pain, to a child named Chiron, with the upper body of a man and the lower body of a horse. Seized with shame and disgust at the sight of this monster, she abandoned him on Mount Pelion in Thessaly.

Thus, Chiron was an illegitimate, half-man, half-horse, son of Cronus, and a half-brother to Zeus.

How Chiron was saved, and what he became

Fortunately, Chiron was found and reared by the god Apollo, who taught him the healing arts, music, and prophecy, while Apollo’s twin sister Artemis taught him archery and hunting. Chiron excelled in every field. It is sometimes said that he invented pharmacy, medicine, and surgery.

For his learning and temperament, he was highly sought after as a tutor. His pupils included many of the greatest heroes, including Perseus, Theseus, Jason, Ajax, Patroclus, and, of course, Achilles. Chiron had a special bond with Achilles, having advised Peleus, his father, how to win over his mother Thetis.

Wounded in the thigh by one of Paris’ arrows, Eurypylus, leader of the Thessalians in the Trojan War, cried out to Patroclus:

I want you to cut out this arrow from my thigh, wash off the blood with warm water and spread soothing ointment on the wound. They say you have some excellent prescriptions that you learnt from Achilles, who was taught by Chiron…

Whereas other centaurs were notorious for their unbridled lust and violence, Chiron, the foster child of Apollo, was all culture and restraint. Unlike other centaurs, he was often depicted clothed rather than naked, and with human rather than equine legs. As half-brother to Zeus, he came from a completely different line from the other centaurs, who were born of Ixion and Nephele.

During his fourth labour to capture the Erymanthian boar, Hercules visited the centaur Pholus in his cave. When Pholus opened a bottle of wine that had been gifted by Dionysus, the intense bouquet attracted the other centaurs and drove them into a frenzy. Hercules defended the cave by firing arrows dipped in the blood of the Lernaean hydra, which he had killed on his second labour. One of the arrows struck Chiron, who, although friendly with Hercules, had been caught in the mêlée.

For all his knowledge and skill Chiron was unable to heal his wound, which became insufferable. But being the immortal son of Cronus, neither was he able to die.

In the end, he struck a bargain with Zeus, whereby he would exchange his immortality for the freedom of Prometheus, who had been bound for all eternity to a rock for stealing fire from the gods and delivering it to humankind.

Interpretation of the myth: The first wound

Chiron is twice-wounded: once at birth, and again towards the end of his life.

The first wound is a deep emotional wound that comes from being a child of rape who is rejected by both his parents. He is quite literally a monster, and now also an orphan and an outcast.

Being half-man, half-animal, Chiron embodies the conflict in all of us between the animal instincts and reason or divinity, between the Dionysian wildness of the other centaurs and the Apollonian light and order of his foster father. Yet, he falls firmly on the Apollonian side, and in many respects outshines the god of light, mastering and even furthering the arts in an attempt to compensate for his early rejection and prove, both to himself and to others, that he too is worthy of love and acceptance.

Chiron turns in particular to the healing arts as a means of healing himself, and not only himself but others too. He shines the light, giving to others that which he himself most needs or needed. Rather than allowing the original wound to fester, he finds within it a source of motivation , even of inspiration, that leads him to great insight and achievement. This in turn invites, or rather imposes, a sense of purpose and service that ennobles and enriches his life in ways that the other centaurs could not even begin to imagine.

Interpretation of the myth: The second wound

Chiron’s second wound is caused by the superego, represented by Hercules, battling against the id, represented by the centaurs riled up by the Dionysian wine. Instead of reconciling himself with the dark side, Hercules desperately fights against it, potentially hurting himself and others in the process—as he does his friend Chiron.

Chiron’s stoical decision to die in the face of unbearable and incurable pain, especially in light of his immortality, raises profound, and surprisingly modern, ethical questions about euthanasia and the desirability of immortality, questions that have never been more pertinent than today.

Chiron is a rare if not unique instance of a god who dies, and, more than that, chooses to die (unlike, say, Jesus). But even in dying, he gives himself up to another. Just like he sublimed his life into wisdom , art, and love, so he sublimed his death into an act of service and sacrifice.

And it is fitting that Chiron's sacrifice is to Prometheus, a god so similar to himself: a great friend of humankind, and wounded for it, wounded, like we all are, for bridging the divide between the mortal and the divine. This is the second wound, the wound in our mortal body, the wound that will not heal.

And so the story of Chiron is the story of how we might be able to cope with the psychological distress and ineluctable physical defeat that is part and parcel of the human condition.
