Gaius Suetonius Tranquillus (Latin: [ˈɡaːiʊs sweːˈtoːniʊs traŋˈkᶣɪlːʊs]), commonly referred to as Suetonius (swih-TOH-nee-əs; c. AD 69 – after AD 122), was a Roman historian who wrote during the early Imperial era of the Roman Empire. His most important surviving work is De vita Caesarum, commonly known in English as The Twelve Caesars, a set of biographies of 12 successive Roman rulers from Julius Caesar to Domitian. Other works by Suetonius concerned the daily life of Rome, politics, oratory, and the lives of famous writers, including poets, historians, and grammarians. A few of these books have partially survived, but many have been lost.
Life
Gaius Suetonius Tranquillus was probably born about AD 69, a date deduced from his remarks describing himself as being about 57 years after Nero's death. His place of birth is disputed, but most scholars place it in Hippo Regius (the modern Annaba), at the time a small north African town in Numidia, in modern-day Algeria. It is certain that Suetonius came from a family of moderate social position, that his father, Suetonius Laetus, was a tribune belonging to the equestrian order (tribunus angusticlavius) in Legio XIII Gemina, and that Suetonius was educated when schools of rhetoric flourished in Rome.
Suetonius was a close friend of senator and letter-writer Pliny the Younger. Pliny describes him as "quiet and studious, a man dedicated to writing". Pliny helped him buy a small property and interceded with the Emperor Trajan (not Hadrian) to grant Suetonius tax immunities usually granted to a father of three, the ius trium liberorum, because he was childless even though he was married; such tax immunities were also granted to thousands of inhabitants of Italy who were part of the empire at the time of Suetonius and Trajan and at the time...the population of Rome is estimated to have been more than 600,000 people. Through Pliny, Suetonius came into favour with Trajan and Hadrian. Suetonius may have served on Pliny's staff when Pliny was imperial governor (legatus Augusti pro praetore) of Bithynia and Pontus (northern Asia Minor) between 110 and 112. Under Trajan he served as secretary of studies (a studiis (precise functions are uncertain)) and director of Imperial archives (a bibliotecis); while under Hadrian, Suetonius became the emperor's secretary (ab epistulis).
