[86] Tac. _Hist._ ii. 89 ‘Quattuor legionum aquilae per frontem totidemque circa e legionibus aliis vexilla, mox duodecim alarum signa et post peditum ordines eques; dein quattuor et triginta cohortes, ut nomina gentium aut species armorum forent, discretae’.
[87] On one of the inscriptions which mentions this officer, iii. 3256, he is ranked among the mounted men of a _cohors equitata_.
[88] For the position of these officers cf. viii. 21567.
[91] viii. 2094 ‘… C. Iulius Dexter vet(eranus), mil(itavit) in ala eq(ues), cur(ator) turmae, armor(um) custos, signifer tur(mae) …’.
[97] iii. 11811. There were of course several of these, and also of the preceding officers.
[99] vi. 225. vi. 2408 also shows seven _equites_ preceding the _signifer turmae_.
[100] vi. 3179, 32797. Both appear also among the _equites cohortales_, iii. 3352, 10589.
[103] ii. 2553; cf. _A. E._ 1910. 4. A detachment of the Cohors I Celtiberorum in Lusitania is under the charge of a centurion of the Cohors I Gallica, a _beneficiarius_ of the procurator, an _imaginifer_ of Legio VII Gemina, and a _tesserarius_ of the Cohors I Celtiberorum.
[109] iii. 1808. We should perhaps add to this group the _capsarius_, _A. E._ 1906. 110.
[112] iii. 8522. In xiii. 6503 the musicians are described collectively as _aeneatores_.
[114] vii. 690. He served in the Cohors I Tungrorum.
[116] xi. 3007. His cognomen is uncertain.
[117] xiii. 6621. One might add M. Mucius Hegetor medicus of the Cohors XXXII Voluntariorum in Pannonia, iii. 10854.
[118] Lucian mentions a doctor of an auxiliary cohort who wrote a history of the Parthian war of Marcus and Verus and must have been a man of some education. Lucian, _de hist. conscrib._ 24.
[120] The record of the career of C. Iulius Dexter quoted above is quite exceptional. Usually only one post is mentioned.
[121] iii. 11213 gives the sequence _eques-optio-decurio_, and 8762 that of _eques-vexillarius-decurio_, but such details are rare.
[122] The _principales_ would be the _vexillarius alae_, the _optio singularium_, and a _duplicarius_ and _sesquiplicarius_ to each _turma_. Of the _immunes_ each _turma_ has its _signifer_, _custos armorum_, and _curator_. The total number of the _beneficiarii_, &c., we do not know, but the inscription of the Equites Singulares quoted above suggests an average of three to a _turma_. In a _cohors quingenaria_ with only 6 commissioned officers and 19 _principales_ (the _imaginifer cohortis_ and the _signifer_, _optio_, and _tesserarius_ of each century) the chances of promotion would be less. This is another reason for the popularity of the cavalry and the desire of cohorts to become _equitata_. Cf. Tac. _Hist._ iv. 19.
