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. Claudius (Full name Tiberius Claudius Caesar Augustus Germanicus) was the grandson of Mark Antony, brother of Germanicus, and the uncle of Caligula. He was descended from both the Julian and the Claudian clans, as was Caligula. He was about 50 years old at the time of Caligula's murder. He never held public office until late in his life, mainly due to his family's concerns as to his health and mental abilities. Suetonius has much to say about Claudius' apparent disabilities, and how the imperial family viewed them, in the "Life of Augustus." The assassination of Caligula caused great terror in the Palace and, according to Suetonius, Claudius, being frightened by the sounds of soldiers scouring the Palace for further victims, hid behind some curtains on a balcony nearby. He was convinced that he would be murdered as well because he was within direct family of Caligula, the last Emperor. A soldier checking the room noticed feet sticking out from underneath the curtains, and upon pulling back the curtains discovered a terrified Claudius. He acclaimed Claudius the new Emperor and took him to the rest of the soldiers, where they carried him out of the Palace on a litter. Claudius was taken to the Praetorian camp, where he was quickly proclaimed Emperor by the troops. We learn from Suetonius that Claudius was the first Roman commander to invade Britain since Julius Caesar a century earlier. Cassius Dio gives a more detailed account of this. He also went farther than Caesar, and made Britain subject to Roman rule. Caesar had "conquered" Britain, but left the Britons alone to rule themselves. Claudius was not as kind. The invasion of Britain was the major military campaign under his reign. According to Suetonius, Claudius suffered from ill health all of his life until he became Emperor, when his health suddenly became excellent. Nonetheless, Claudius suffered from a variety of maladies, including fits and epileptic seizures, a funny limp, as well as several personal habits like a bad stutter and excessive drooling when overexcited. Suetonius found much delectation in recounting how the pitiable Claudius was ridiculed in his imperial home due to these ailments. In his account of Caligula Suetonius also includes several letters written by Augustus to his wife, Livia, expressing concern for the imperial family's reputation should Claudius be seen with them in public. Suetonius goes on to accuse Claudius of cruelty and stupidity, assigning some of the blame to his wives and freedmen. Suetonius discusses several omens that foretold the assassination of Claudius. He mentions a comet that several Romans had seen shortly before the assassination. As mentioned earlier, comets were believed to foretell the deaths of significant people. Per Suetonius, Claudius, under suggestions from his wife Messalina, tried to shift this deadly fate from himself to others by various fictions, resulting in the execution of several Roman citizens, including some Senators and aristocrats. Suetonius paints Claudius as a ridiculous figure, belittling many of his acts and attributing his good works to the influence of others. Thus the portrait of Claudius as the weak fool, controlled by those he supposedly ruled, was preserved for the ages.
