Chiron Sightings

Argonautica by Valerius Flaccus 1BC - 100
The wise centaur mentors young Jason in this epic poem.
Inferno by Dante 1308 - 1321
In the seventh circle of Hell, Chiron leads a bunch of other centaurs as they fire arrows at any damned soul trying to escape from the Phlegethon. How kind.
Percy Jackson and the Olympians Series by Rick Riordan 2005
Chiron is rightly given the role of head teacher at Camp Halfblood in the Percy Jackson series. Rick Riordan knew his stuff.
The Lightning Thief 2010
Chiron hits the big screen in the film version of the first book of the Percy Jackson series. Pierce Brosnan pretty much nails it.
