The first point to notice in this list is the smallness of the contingent from the senatorial provinces. So small is it that Mommsen desired to see here evidence of a constitutional principle.[179] The auxilia were ‘gewissermassen eine Hausmacht des Kaisers’ and as such raised only in the provinces governed by his _legati_. Such instances as were then known of regiments raised in senatorial provinces were, he thought, susceptible of explanation. The alae Vocontiorum, for instance, represented a _civitas foederata_ which was not, strictly speaking, a part of the senatorial province of Narbonensis. It does not, however, seem possible to maintain this theory. The Cohors I Cretum[180] is a certain case of a regiment from a senatorial province, nor can it be really doubted that contingents were also drawn from Cyprus[181] and Cyrene.[182] Indeed, it is difficult to see what legal or political obstacle should prevent Augustus and his successors from utilizing the military material available in the senatorial provinces. Even if Mommsen is right in believing that conscription, as opposed to the enrolment of volunteers, could only take place in a senatorial province with the authority of the Senate (and this theory is questioned by both Gardthausen and Liebenam),[183] there is no reason why levies should not have been made for the auxilia under these conditions when they certainly were made for the legions.[184] In no case did any military power remain in the hands of the Senate, since the recruits would immediately be marched away to garrison imperial provinces. As a matter of fact, the reason for the smallness of the senatorial contingent seems to have been a practical one. Few auxilia were raised from Narbonensis and Baetica, because the greater part of the inhabitants of these provinces had received the franchise and were consequently eligible for service in the legions. Achaia, Asia, and to a certain extent Macedonia, were treated as being on the same footing, partly because Greeks did actually serve in the Eastern legions, partly because of the Philhellenic policy of the imperial government, which would not deny to the Greek states, although they were technically unenfranchised, the privileges enjoyed by the enfranchised urban communities of the West. Also no doubt the Greek of the period was not rated highly as a fighting man. On the other hand, from Cyrenaica, Crete, Cyprus, parts of Macedonia, and Africa[185] useful troops could be and were obtained. The way in which the system worked is shown by the case of Noricum, which, although an imperial province, included many enfranchised communities and contributed recruits to the Rhine legions in the middle of the first century.[186] Its contribution of auxilia in consequence is limited to one ala and one cohort, as against the eighteen regiments furnished by the neighbouring province of Raetia.
