Sallust was a well-known Roman historian and politician, a friend of Julius Caesar who made him governor of Numdia in North Africa. Sallust made a fortune there, then he returned to Rome where he became a writer of history.
Sallust concentrated in his writings on the critical stages in the decline of the Roman republic. He treated history as more than just a chronicle of events; he stated the reasons for each event. (Luther mentions Sallust in the Gospel Sermon for Oculi 3)
Major works are: 'The Jugurthine War', and 'The Cataline conspiracy'.
