[-13-] The people urged Augustus very strongly to rescind the sentence of exile passed upon his daughter, but he answered that fire would mix with water before she should be brought back. And the populace did throw a good deal of fire into the Tiber. For the time being they accomplished nothing, but later they brought such pressure to bear that she was at last moved from the island to the mainland. And later the outbreak of war with the Celtæ found Augustus worn out in body (by reason of old age and sickness) and incapable of taking the field. Yielding, then, partly to the requirements of the situation and partly to the persuasions of Julia[10] (who had already been restored from banishment) he both adopted Tiberius and sent him out[11] against the Celtæ, granting him the tribunician authority for ten years. [A.D. 4 (_a. u._ 757)] Yet suspecting that he might lose his head and fearing a possible insurrection he adopted for him also his nephew Germanicus, though Tiberius himself had a son. After this he took courage, and feeling that he had successors and supporters, he became desirous to organize the senate once more. So he nominated the ten senators whom he most honored and appointed three of them, selected by lot, to be scrutinizers. There were not many, however, who either imposed sentence on themselves beforehand,--permission being given them to do so, just as previously,--or were retired against their will. This business, then, was managed by others. The emperor himself took a census of the inhabitants of Italy possessing property valued at not less than five myriad denarii. The weaker citizens and those dwelling outside of Italy he did not compel to undergo the taking of a census, for he feared that they might be disturbed and show insubordination of some sort. And in order that he might not seem to be acting in the capacity of censor (for the reason I mentioned before) [12] he assumed proconsular powers for the purpose of completing the census and accomplishing the purification. And inasmuch as many of the young men of the senatorial class and of the equestrian, as well, had grown poor though not at fault for it themselves, he made up to most of them the required amount of property, and in the case of some eighty increased it to thirty myriads. [A.D. 4 ( _a. u._ 757) ] Since, also, many were giving unrestricted emancipation to their slaves, he directed what age the manumitter and likewise the person to be liberated by him must have reached: moreover, what regulations people in general, and the former masters, should observe toward those made freedmen.
