Numerarii.
(6) The Numerarii (whose exact number is not stated in the 'Notitia'[158]) were the cashiers of the Praefect's office. Though frequently mentioned in the Theodosian Code, and though persons exercising this function must always have existed in a great Court of Justice like the Praefect's, we hear but little of them from Cassiodorus[159]; and Lydus' notices of the διαψηφισται, who seem to correspond to the Numerarii[160], are scanty and imperfect. Our German commentator has collected the passages of the Theodosian Code which relate to this class of officers, and has shown that on account of their rapacity and extortion their office was subjected to a continual process of degradation. All the Numerarii, except those of the two highest classes of judges[161], were degraded into Tabularii, a name which had previously indicated the cashiers of a municipality as distinguished from those in the Imperial service; and the Numerarii, even of the Praetorian Praefect himself, were made subject to examination by torture. This was not only to be dreaded on account of the bodily suffering which it inflicted, but was also a mark of the humble condition of those to whom it was applied.
Scriniarius Curae Militaris.
We may perhaps see in the Scriniarius Curae Militaris of Cassiodorus[162] one of these Numerarii detailed for service as paymaster to the soldiers who waited upon the orders of the Praefect.
Subadjuvae.
(7) The Subadjuvae. This is probably a somewhat vague term, like Adjutores, and indicates a second and lower class of cashiers who acted as deputies for the regular Numerarii.
Cura Epistolarum.
(8) Cura Epistolarum. The officer who bore this title appears to have had the duty of copying out all letters relating to fiscal matters[163]. This theory as to his office is confirmed by the words of Cassiodorus (Var. [xi. 23]): 'Let Constantinian on his promotion receive the care of the letters relating to the land-tax' (Hic itaque epistolarum canonicarum curam provectus accipiat).
Regerendarius, or Regendarius.
(9) Regerendarius, or Regendarius[164]. This officer had the charge of all contracts relating to the very important department of the Cursus Publicus, or Imperial Mail Service. At the time of the compilation of the 'Notitia' only one person appears to have acted in this capacity under each Praefect. When Lydus wrote, there were two Regendarii in each Praefecture, but, owing to the increasing influence of the Magister Officiorum over the Cursus Publicus[165], their office had become apparently little more than an ill-paid sinecure. As we hear nothing of similar changes in the West, the Cursus Publicus was probably a part of the public service which was directly under the control of Cassiodorus when Praetorian Praefect, and was administered at his bidding by one or more Regendarii.
