11. When Valentinian saw this, his confidence increased; he adorned his son with a crown and with the robes befitting his now supreme rank, and kissed him; and then thus addressed him, brilliant as he appeared, and giving careful attention to all his words:—
12. "You wear now," said he, "my Gratian, the imperial robe, as we have all desired, which has been conferred on you with favourable auspices by my will and that of our comrades. Therefore now, considering the weight of the affairs which press upon us, gird yourself up as the colleague of your father and your uncle; and accustom yourself to pass fearlessly with the infantry over the Danube and the Rhine, which are made passable by the frost, to keep close to your soldiers, to devote your blood and your very life with all skill and deliberation for the safety of those under your command; to think nothing unworthy of your attention which concerns any portion of the Roman empire.
13. "This is enough by way of admonition to you at the present moment, at other times I will not fail to give further advice. Now you who remain, the defenders of the state, I entreat, I beseech you to preserve with a steady affection and loyalty your youthful emperor thus intrusted to your fidelity."
14. These words of the emperor were accepted and ratified with all possible solemnity; Eupraxius, a native of Mauritania Cæsariensis, at that time master of the records, led the way by the exclamation, "The family of Gratian deserves this." And being at once promoted to be quæstor, he set an example of judicious confidence worthy of being imitated by all wise men; especially as he in no wise departed from the habits of his fearless nature, but was at all times a man of consistency and obedient to the laws, which, as we have remarked, speak to all men with one and the same voice under the most varied circumstances. He at this time was the more steady in adhering to the side of justice which he always espoused, because on one occasion when he had given good advice, the emperor had attacked him with violence and threats.
15. After this, the whole assembly broke out into praises of both emperors, the elder and the new one; and especially of the boy, whose brilliant eyes, engaging countenance and person, and apparent sweetness of disposition, recommended him to their favour. And these qualities would have rendered him an emperor worthy to be compared to the most excellent princes of former times, if fate had permitted, and his relations who even then began to overshadow his virtue, before it was firmly rooted, with their own wicked actions.
16. But in this affair, Valentinian went beyond the custom which had been established for several generations, in making his brother and his son, not Cæsar, but emperors; acting indeed in this respect with great kindness. Nor had any one yet ever created a colleague with powers equal to his own, except the emperor Marcus Aurelius, who made his adopted brother Verus his colleague in the empire without any inferiority of power.

§ 1. After these transactions had been thus settled to the delight both of the prince and of the soldiers, but a few days intervened; and then Avitianus, who had been deputy, accused Mamertinus, the prefect of the prætorium, of peculation, on his return from the city whither he had gone to correct some abuses.
