The purpose of this essay is to study the crimes and punishments in the Roman army, how ancient authors describe this phenomenon and the differences between the authors descriptions. The results of the essay are that the authors mostly describe crimes such as mutiny and desertion. Ruffus is the only one who mentions and describes other types of crimes than mutiny and desertion, such as theft, rape and disobedience. The reason why there is a difference between Ruffus and the other authors are that Ruffus wrote a collection of laws in the Roman army but the other authors wrote biographies and histories and therefore they only mentioned the most dramatic thing that happened, such as a mutiny in the army for example..
