Cornicularius

Cornicularius the wearer of a CORNICULUM; hence in Roman armies an adjutant or aide-de-camp attached to the higher military commanders. In early times there was perhaps only one to each legion, under the orders of the tribunus militum whose turn it was to command (Frontin. Strateg. 3.14, 1; V. Max. 6.1, 11). From the time of Marius and under the empire the legatus of each legion had one cornicularius, the tribune in command another: hence two cornicularii are usually mentioned in inscriptions (C. I. L. 2.4122), though sometimes a single one occurs (C. I. L. 1681). Provincial governors had likewise their cornicularii,--two apiece, it would seem, as we find officium corniculariorum in the plural (C. I. L. 3.3543); and if the governor were of consular rank, his subordinate was cornicularius consularis (ib. 1106; cf. 3543). Other officers found with cornicularii attached to them are the praefectus praetorio (C. I. L. 3846; Orelli, 3157, 3488), perhaps the praefectus urbi, the tribunes of the praetorian (C. I. L. 2.2610, 3.2887) and urban cohorts (Orelli, 3462; Mommsen, Inscr. R. Neap. 1459), the praefectus vigilum (Orelli, 3456; Henzen, 6753, 7170), the praefectus annonae (Orelli, 3489), &c. (See fuller references to inscriptions in Marquardt, Staatsverw. 2.528-9.)
