De vita Caesarum, known as The Twelve Caesars, is a set of twelve biographies, each about one of the Roman emperors, including one on Julius Caesar. It was written by Gaius Suetonius Tranquillus, commonly referred to as Suetonius, in 121. Considered highly significant in antiquity, The Twelve Caesars has remained a major source of Roman history.
Gaius Suetonius Tranquillus was probably born in AD69 - the famous 'year of the four Emperors'. From the letters of Suetonius' close friend Pliny the Younger we learn that he practiced briefly at the bar, avoided political life, and became chief secretary to the Emperor Hadrian (AD117-38). Suetonius seems to have lived to a good age and probably died around the year AD140.
