Ancient Roman tastes may have run toward the violent and perverse (and the violently perverse), but the modern concept of Roman gladiators as chattel-like grist for the mill of the Roman entertainment complex is somewhat exaggerated. Successful gladiators were popular with the Roman public, and anthropological records suggest they were most likely treated accordingly, often having long careers and being attended to by trainers and doctors.
