The only thing for which he can fairly be censured was his love of money. For not content with reviving the imposts which had been repealed under Galba, he added new and heavy burdens, increasing the amount of tribute paid by the provinces, in some cases actually doubling it, and quite openly carrying on traffic which would be shameful even for a man in private life; for he would buy up certain commodities merely in order to distribute them at a profit. He made no bones of selling offices to candidates and acquittals to men under prosecution, whether innocent or guilty. He is even believed to have had the habit of designedly advancing the most rapacious of his procurators to higher posts, that they might be the richer when he later condemned them ; in fact, it was common talk that he used these men as sponges, because he, so to speak, soaked them when they were dry and squeezed them when they were wet. Some say that he was naturally covetous and was taunted with it by an old herdsman of his, who on being forced to pay for the freedom for which he earnestly begged Vespasian when he became emperor, cried: “The fox changes his fur, but not his nature.’ Others on the contrary believe that he was driven by necessity to raise money by spoliation and robbery because of the desperate state of the treasury and the privy purse; to which he bore witness at the very beginning of his reign by declaring that forty thousand millions were needed to set the State upright. This latter view seems the more probable, since he made the best use of his gains, ill-gotten though they were.
