I, Claudius by Robert Graves
I, Claudius deals sympathetically with the life of the Roman Emperor Claudius and cynically with the history of the Julio-Claudian Dynasty and Roman Empire, from Julius Caesar's assassination in 44 BC to Caligula's assassination in AD 41. Graves's interpretation of the story owes much to the histories of Tacitus, Plutarch, and (especially) Suetonius.
