“The system of administration was thoroughly remodelled. The Sullan proconsuls and propraetors had been in their provinces essentially sovereign and practically subject to no control; those of Caesar were the well-disciplined servants of a stern master, who from the very unity and life-tenure of his power sustained a more natural and more tolerable relation to the subjects than those numerous, annually changing, petty tyrants. The governorships were no doubt still distributed among the annually-retiring two consuls and sixteen praetors, but, as the Imperator directly nominated eight of the latter and the distribution of the provinces among the competitors depended solely on him, they were in reality bestowed by the Imperator. The functions also of the governors were practically restricted. His memory was matchless, and it was easy for him to carry on several occupations simultaneously with equal self-possession. Although a gentleman, a man of genius, and a monarch, he had still a heart. So long as he lived, he cherished the purest veneration for his worthy mother Aurelia… to his daughter Julia he devoted an honourable affection, which was not without reflex influence even on political affairs. With the ablest and most excellent men of his time, of high and of humbler rank, he maintained noble relations of mutual fidelity… As he himself never abandoned any of his partisans… but adhered to his friends--and that not merely from calculation--through good and bad times without wavering, several of these, such as Aulus Hirtius and Gaius Matius, gave, even after his death, noble testimonies of their attachment to him. 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, and the raising of the taxes was probably even now committed in the provinces substantially to imperial officials, 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.”
