[493] Of the nineteen regiments mentioned (taking ‘Augusta Syriaca’ as the title of one ala, not two), eight are mentioned on the Syrian diploma of 157, two on the Palestine diplomata of 86 and 139, and one on the Egyptian diploma of 83. Of the remainder two have left inscriptions in the East, two seem to have come from the Danube, and only four are otherwise unknown. [494] Should probably be _equestris_, the regiment belonging to the same series as the Cohors VI Equestris which formed part of the garrison of Bithynia when Pliny was governor. Cf. Pliny, _Ep._ x. 106. The meaning of the title is obscure, unless _equestris_ simply = _equitata_. [495] Numbers II and III in this series were certainly _miliariae_, as probably all were. [496] I agree with Cichorius in distinguishing the Cohors I Sugambrorum V. E. from the Cohors I Claudia Sugambrorum. The first is probably identical with the regiment mentioned by Tacitus as being in Moesia in A.D. 26 (Tac. _Ann._ iv. 47), the second a later creation distinguished as such by its secondary title. [497] Mentioned in the _cursus honorum_ of a _praefectus_ whose service lay almost entirely in the Eastern provinces. On this ground and because Cohorts I and II of this series were certainly in the East the regiment has been assigned to Syria. This second argument applies to Cohort IV. Both regiments were in any case in existence at this period. [498] The title Ulpia is not given in these cases but presumably belonged to the whole series. [499] Or is this a cohort converted into an ala with the increase of cavalry in the fourth century? In this case it may be identical with the Cohors II Ulpia Equitata mentioned below. [500] Curiously enough the regiment appears in the Syrian diploma for 157. [501] Cagnat, however, considers that the regiment was in the province as early as 150, relying on viii. 3917, p. 955. [502] In the first inscription the regiment is commanded by a _tribunus_. [503] This inscription does not, however, prove conclusively that the regiment was stationed in Spain. [504] Suet. Fr. 278 (_Reiffer._) ‘Legio dicitur virorum electio fortium vel certus militum numerus, id est V̅ DC.’ [505] Four were at Rome, one at Lugudunum, and one at Carthage. [506] Marcus added II and III Italica to garrison Raetia and Noricum; Septimius Severus the three legiones Parthicae, of which I and III were stationed in Mesopotamia and II at Alba in Italy.
