In the same year the Tiber, swollen by continuous rains, flooded the level portions of the city. Its subsidence was followed by a destruction of buildings and of life. Thereupon Asinius Gallus proposed to consult the Sibylline books. Tiberius refused, veiling in obscurity the divine as well as the human. However, the devising of means to confine the river was intrusted to Ateius Capito and Lucius Arruntius. Achaia and Macedonia, on complaining of their burdens, were, it was decided, to be relieved for a time from pro-consular government and to be transferred to the emperor. Drusus presided over a show of gladiators which he gave in his own name and in that of his brother Germanicus, for he gloated intensely over bloodshed, however cheap its victims. This was alarming to the populace, and his father had, it was said, rebuked him. Why Tiberius kept away from the spectacle was variously explained. According to some, it was his loathing of a crowd, according to others, his gloomy temper, and a fear of contrast with the gracious presence of Augustus. I cannot believe that he deliberately gave his son the opportunity of displaying his ferocity and provoking the people's disgust, though even this was said.
