Sallust (86–c. 35 bc) is the earliest Roman historian of whom complete works survive, a senator of the Roman Republic and younger contemporary of Cicero, Pompey and Julius Caesar. His Catiline’s War tells of the conspiracy in 63 bc led by L. Sergius Catilina, who plotted to assassinate numerous senators and take control of the government, but was thwarted by Cicero. Sallust’s vivid account of Roman public life shows a Republic in decline, prey to moral corruption and internal strife. In The Jugurthine War he describes Rome’s fight in Africa against the king of the Numidians from 111 to 105 bc, and provides a damning picture of the Roman aristocracy. Also included in this volume are the major surviving extracts from Sallust’s now fragmentary Histories, depicting Rome after the death of the dictator Sulla.
A literal translation. According to Wikipedia: "Gaius Sallustius Crispus, usually anglicised as Sallust (86 BC – c. 35 BC) was a Roman historian, politician, and novus homo from a provincial plebeian family. Sallust was born at Amiternum in the country of the Sabines and was a popularis, opposer of the old Roman aristocracy throughout his career, and later a partisan of Julius Caesar. Sallust is the earliest known Roman historian with surviving works to his name, of which we have Catiline's War (about the conspiracy in 63 BC of L. Sergius Catilina), The Jugurthine War (about Rome's war against the Numidians from 111 to 105 BC), and the Histories (of which only fragments survive). Sallust was primarily influenced by the Greek historian Thucydides and amassed great (and ill-gotten) wealth from his governorship of Africa."
