"To Chiron, near you there"

(Canto 12, line 65)

Chiron, according to an archaic myth, was the son of the Titan Cronus. He is probably the most prominent among the Centaurs, and is their leader in Dante's poem. He had a reputation for wisdom, was the teacher of Achilles and a master of healing and surgery. Immortal by birth, he gave up his immortality so that Zeus would spare the life of Prometheus. After his death, his body became the constellation Centaurus.
