The Twelve Caesars

The Twelve Caesars, probably written in Hadrian’s time, is a collective biography of the Roman Empire’s first leaders, Julius Caesar (the first few chapters are missing), Augustus, Tiberius, Caligula, Claudius, Nero, Galba, Otho, Vitellius, Vespasian, Titus and Domitian. The book was dedicated to a friend Gaius Septicius Clarus, a prefect of the Praetorian Guard in 119.
The work tells the tale of each Caesar’s life according to a set formula: the descriptions of appearance, omens, family history, quotes, and then a history are given in a consistent order for each Caesar.
