Gaius Suetonius Tranquillus, commonly known as Suetonius (c. 69 - after 122 AD), was a Roman historian belonging to the equestrian order who wrote during the early Imperial era of the Roman Empire. His most important surviving work is a set of biographies of twelve successive Roman rulers, from Julius Caesar to Domitian, entitled De Vita Caesarum. He recorded the earliest accounts of Julius Caesar's epileptic seizures. Other works by Suetonius concern the daily life of Rome, politics, oratory, and the lives of famous writers, including poets, historians, and grammarians. A few of these books have partially survived, but many have been lost. In the book of the last of the short-lived emperors, Suetonius briefly describes the reign of Vitellius. Suetonius says that it was the followers of Vitellius who had assassinated Otho. This book gives an unfavorable picture of Vitellius; however it should be remembered that Suetonius' father was an army officer who had fought for Otho and against Vitellius at the first Battle of Bedriacum, and that Vespasian basically controlled history when he ascended to the throne. Anything written about Vitellius during the Flavian dynasty would have to paint him in a bad light. Suetonius includes a brief description of the family history of Vitellius, and related omens. Suetonius finally describes the assassination of Vitellius. According to Suetonius, Vitellius was dragged naked by Roman subjects, tied to a post, and had animal waste thrown at him before he was killed. However, unlike the prior two emperors, it was not the next emperor who killed Vitellius. The next emperor and his followers had been waging a war against the Jews in Judaea at the time. The death of Vitellius and subsequent ascendance of his successor ended the worst year of the early principate.
