Suetonius

Gaius Suetonius Tranquillus (c. AD 69 – after AD 122) was a Roman historian and biographer best known for his work De vita Caesarum, or The Twelve Caesars, which provides detailed and often gossipy biographies of Julius Caesar and the first eleven Roman emperors. He served under emperors Trajan and Hadrian in high administrative roles, including as secretary ab epistulis, but fell out of favor with Hadrian around 121-122 due to personal issues involving the empress. Suetonius's thematic and anecdotal style prioritized engaging narratives over strict chronology, influencing later biographers.
