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. Titus was the elder son of Vespasian, and second emperor of the Flavian dynasty. As Suetonius writes: "The delight and darling of the human race." Titus was raised in the imperial court, having grown up with Britannicus. The two of them were told a prophesy pertaining to their future where Britannicus was told that he would never succeed his father and that Titus would. The two were so close that when Britannicus was poisoned Titus who was present tasted it and was nearly killed. "When Titus came of age, the beauty and talents that had distinguished him as a child grew even more remarkable." Titus was extremely adept at the arts of "war and peace." He made a name for himself as a colonel in Germany and Britain; however, he really flourished as a commander under his father in Judea and when he took over the siege of Jerusalem. Titus' near six-month siege of Jerusalem ended with the destruction of the Herod's Temple and the expulsion of Jews from Jerusalem. The resulting period is known as the Jewish diaspora (roughly from 70 till 1948). Titus had a love affair with the Jewish Queen Berenice, whom he brought briefly to Rome. As Emperor he tried to be magnanimous and always heard petitions with an open-mind. And after going through a day having not granted any favors he commented that "I have wasted a day." During his reign he finished what would be the most enduring reminder of his family, the Flavian Amphitheater. His reign was tainted by the eruption of Mt. Vesuvius, a great fire in Rome, and one of the worst plagues "that had ever been known." These catastrophes did not destroy him, rather, as Suetonius remarks, he rose up like a father caring for his children. And although he was deified, his reign was short. He died from poison (possibly by his brother, Domitian), having only reigned for "two years, two months and twenty days." At the time of his death he "[drew] back the curtains, gazed up at the sky, and complained bitterly that life was being undeservedly taken from him-since only a single sin lay on his conscience."
