It has been found that Roman gladiators consumed a mostly vegetarian diet and drank ashes after training as a tonic. These are the findings of anthropological investigations carried out on bones of warriors discovered during excavations in the ancient city of Ephesos.
The idea of single combat in the Roman Empire immediately evokes the powerful image of the gladiator standing over a downed opponent, his gladius raised for the glory of the patron of the games, the crowds embroiled with the bloodlust so easily awakened.
