appearance promoted essentially that general Gallic homogeneity, which went there hand in hand with the Latinising. [Sidenote: Composition of the diet.] The composition of the diet, which is known to us with tolerable accuracy,[48] shows in what way the question of nationalities was treated by the government. Of the sixty, afterwards sixty-four, cantons represented at the diet, only four fall to the Iberian inhabitants of Aquitania--although this region between the Garonne and the Pyrenees was divided among a very much larger number of, as a rule, small tribes--whether it was that the others were excluded altogether from representation, or that those four represented cantons were the meeting-places of canton-unions.[49] Afterwards, probably in the time of Trajan, the Iberian district was separated from the Lyons diet, and had an independent representation given to it.[50] On the other hand, the Celtic cantons in that organisation, with which we have formerly become acquainted, were substantially all represented at the diet, and likewise the half or wholly Germanic,[51] so far as at the time of the institution of the altar they belonged to the empire. That there was no place in this cantonal representation for the capital of Gaul was a matter of course. Moreover, the Ubii do not appear at the diet of Lyons, but sacrifice at their own altar of Augustus: this was, as we saw (p. 35), a remnant, which was allowed to subsist, of the intended province of Germany.
