The size of the auxiliary cohorts is a matter of even greater difficulty. Hyginus states, and there seems no reason to doubt his statement, that a _cohors miliaria_ was divided into ten centuries, a _cohors quingenaria_ into six.[52] Archaeological evidence supports this statement and suggests further that the centuries were in each case of the same size, since the centurial barracks in the fort at Housesteads, in Northumberland, which was occupied by a _cohors miliaria_, offer almost precisely the same accommodation as those in the Scottish fort at Newstead, which are clearly designed to accommodate two _cohortes quingenariae_. The question to be decided is whether these centuries contained 80 or 100 men each. In either case, one of the titles must be a misnomer, since six centuries of 100 would make a _cohors quingenaria_ consist of 600 men, while ten centuries of 80 would only give 800 men for a _cohors miliaria_. On the whole, although Hyginus suggests the higher figure, the lower is probably to be preferred. Certainly the Coptos inscription cited above, which is probably the most valuable evidence which we possess, clearly indicates centuries of 80. The most important evidence on the other side is that of Josephus, who describes some cohorts which belonged to the Syrian army in 67 A.D. as containing ἀνὰ χιλίους πεζούς.[53] His succeeding statement, however, that other cohorts, by which _cohortes equitatae quingenariae_ are apparently meant, contained 600 infantry and 120 cavalry, suggests that he may be basing his reckoning simply on the number of centuries. Few would defend his calculation in the second instance, and he may be equally wrong in the first. On the whole, therefore, it seems safer to assume establishments of 480 and 800 men for _cohortes quingenariae_ and _miliariae_ respectively, although it remains, of course, possible that the size of the cohorts was altered between the Jewish war of 66-70 and the period of the erection of those frontier forts upon which we have been relying for our evidence.
