Gaius Suetonius Tranquillus (69-122 AD) was the author of the biographies of "The Twelve Caesars," rulers of Rome from Julius Caesar to Domitian, one of the most important sources for Roman history of the 1st Century AD. Suetonius was born at Hippo Reggia (in modern Algeria). He became a close friend of Pliny the Younger and, through him, came into favour first with Trajan, and then with Hadrian. In 119 AD, however, Hadrian dismissed him because of an adulterous affair with the Empress Vibia Sabina.
