The functions also of the governors were practically restricted. The superintendence of the administration of justice and the administrative control of the communities remained in their hands; but their command was paralyzed by the new supreme command in Rome and its adjutants associated with the governor,(84) and the raising of the taxes was probably even now committed in the provinces substantially to imperial officials,(85) so that the governor was thenceforward surrounded with an auxiliary staff which was absolutely dependent on the Imperator in virtue either of the laws of the military hierarchy or of the still stricter laws of domestic discipline.

While hitherto the proconsul and his quaestor had appeared as if they were members of a gang of robbers despatched to levy contributions, the magistrates of Caesar were present to protect the weak against the strong; and, instead of the previous worse than useless control of the equestrian or senatorian tribunals, they had to answer for themselves at the bar of a just and unyielding monarch. The law as to exactions, the enactments of which Caesar had already in his first consulate made more stringent, was applied by him against the chief commandants in the provinces with an inexorable severity going even beyond its letter; and the tax-officers, if indeed they ventured to indulge in an injustice, atoned for it to their master, as slaves and freedmen according to the cruel domestic law of that time were wont to atone.
