[Footnote 128: Ib. iii. 22-24.] 'Now that, if I am not mistaken, we have described all the various official grades, it is meet to set forth the history of the Cornicularius, the venerable head of the Civil Service, the man who, as beginning and ending, sums up in himself the complete history of the whole official order. The mere antiquity of his office is sufficient to establish his credit, seeing that he was the leader of his troop for 1,300 years, and made his appearance in the world at the same time with the sacred City of Rome itself: for the Cornicularius was, from the first, attendant on the Master of the Horse, and the Master of the Horse on the King, and thus the Cornicularius, if he retained nothing of his office but the name, would still be connected with the very beginnings of the Roman State. 'But from the time when Domitian appointed Fuscus to the office of Praefect of the Praetorians (an office which had been instituted by Augustus), and abolished the rank of Master of the Horse, taking upon himself the command of the army[129], everything was changed. Henceforward, therefore, all affairs that were transacted in the office of the Praefect were arranged by the Cornicularius alone, and he received the revenues arising from them for his own refreshment. This usage, which prevailed from the days of Domitian to our own Theodosius, was then changed, on account of the usurpation of Rufinus. For the Emperor Arcadius, fearing the overgrown power of the Praefectoral office, passed a law that the Princeps of the Magister [Officiorum]'s staff[130] ... should appear in the highest courts, and should busy himself with part of the Praefect's duties, and especially should enquire into the principle upon which orders for the Imperial post-horses ([Greek: synthemata]; _evectiones_) were granted[131].... This order of Arcadius was inscribed in the earlier editions of the Theodosian Code, but has been omitted in the later as superfluous. [Footnote 129: This seems to be the meaning of Lydus, but it is not clearly expressed.] [Footnote 130: There is something wanting in the text here.] [Footnote 131: See Cod. Theod. vi. 29. 8, which looks rather like the law alluded to by Lydus, notwithstanding his remark about its omission.]
