Sejanus meanwhile, dazed by his extravagant prosperity and urged on too by a woman's passion, Livia now insisting on his promise of marriage, addressed a memorial to the emperor. For it was then the custom to apply to him by writing, even though he was at Rome. This petition was to the following effect:—The kindness of Augustus, the father, and then the many favourable testimonies of Tiberius, the son, had engendered the habit of confiding his hopes and wishes to the ears of emperors as readily as to those of the gods. The splendor of high distinctions he had never craved; he had rather chosen watchings and hardships, like one of the common soldiers, for the emperor's safety. But there was one most glorious honour he had won, the reputation of being worthy of an alliance with a Cæsar. This was the first motive of his ambition. As he had heard that Augustus, in marrying his daughter, had even entertained some thoughts of Roman knights, so if a husband were sought for Livia, he hoped Tiberius would bear in mind a friend who would find his reward simply in the glory of the alliance. He did not wish to rid himself of the duties imposed on him; he thought it enough for his family to be secured against the unjust displeasure of Agrippina, and this for the sake of his children. For, as for himself, enough and more than enough for him would be a life completed while such a sovereign still reigned.
