In the consulship of Marcus Silanus and Lucius Norbanus, Germanicus set out for Egypt to study its antiquities. His ostensible motive however was solicitude for the province. He reduced the price of corn by opening the granaries, and adopted many practices pleasing to the multitude. He would go about without soldiers, with sandalled feet, and apparelled after the Greek fashion, in imitation of Publius Scipio, who, it is said, habitually did the same in Sicily, even when the war with Carthage was still raging. Tiberius having gently expressed disapproval of his dress and manners, pronounced a very sharp censure on his visit to Alexandria without the emperor's leave, contrary to the regulations of Augustus. That prince, among other secrets of imperial policy, had forbidden senators and Roman knights of the higher rank to enter Egypt except by permission, and he had specially reserved the country, from a fear that any one who held a province containing the key of the land and of the sea, with ever so small a force against the mightiest army, might distress Italy by famine.
