The Twelve Caesars
Suetonius was an equestrian who held administrative posts during the reigns of Trajan and Hadrian. "The Twelve Caesars" details a biographical history of the principate from the birth of Julius Caesar to the death of Domitian in AD 96. Like Tacitus, he drew upon the imperial archives, as well as histories by Aufidius Bassus, Marcus Cluvius Rufus, Fabius Rusticus and Augustus' own letters.
