Substantially these same titles were borne by the Illustres to whom Cassiodorus (himself one of them) addressed his 'Various Letters.' The second and the sixth (the Praetorian Praefect of the Gauls, and the Master of the Horse for the Gauls) may possibly have disappeared; and yet, in view of the fact that Theodoric was during the greater part of his reign ruler of a portion of Gaul, it is not necessary to assume even this change. Into the question of the military officers I will not enter, as I confess that I do not understand the relations (whether co-ordinate or subordinated one to another) of the two pairs of officers, Nos. 4 and 5 and Nos. 12 and 13. The rank and duties of the Praetorian Praefect of Italy, the Master of the Offices, and the Quaestor have already been described in the first chapter. It will be well to say a few words as to the four remaining civil dignitaries, the Praefect of the City, the Grand Chamberlain, the Count of Sacred Largesses, and the Count of the Private Domains. [Sidenote: Praefect of the City.] (_a_) The _Praefectus Urbis Romae_ was by virtue of his office head of the Senate. He had the care of the Annona or corn-largesses to the people, the command of the City-watch, and the duty of keeping the aqueducts in proper repair. The shores and channel of the Tiber, the vast _cloacae_ which carried off the refuse of the City, the quays and warehouses of Portus at the river's mouth were also under his authority. The officer who was charged with taking the census, the officers charged with levying the duties on wine, the masters of the markets, the superintendents of the granaries, the curators of the statues, baths, theatres, and the other public buildings with which the City was adorned, all owned the supreme control of the Urban Praefect. At the beginning of the Fifth Century the _Vicarius Urbis_ (whom it is difficult not to think of as in some sort subject to the _Praefectus Urbis_), had jurisdiction over all central and southern Italy and Sicily. But if this was the arrangement then, it must have been altered before the time of Cassiodorus, who certainly appears as Praetorian Praefect to have wielded authority over the greater part of Italy. He states, however[113], that the Urban Praefect had, by an ancient law, jurisdiction, not only over Rome itself, but over all the district within 100 miles of the capital.
