The Twelve Caesars (Suetonius)

Twelve lives — Julius Caesar and the eleven emperors from Augustus to Domitian — written around AD 121 by a man who had held secretarial posts inside the imperial household and had seen the archives. Suetonius does not write continuous narrative. Each life is organised by category: ancestry, career, appearance, domestic habits, public works, cruelties, omens, death. The result is the source for most of what is popularly known about the early emperors, including the material about Tiberius and Caligula that later historians treat with caution.

The categorical method is exactly what makes it useful and what makes it unreliable: gossip and state documents are arranged side by side under the same headings, and Suetonius rarely indicates which is which.

Context: The list runs the Roman material as a set — Livy on the republic’s founding, Tacitus on the early empire’s politics, Suetonius on its rulers as men — and Einhard copied this book’s structure directly when he wrote Charlemagne’s life seven centuries later.
