[47: For the _arca Galliarum_, the freedman of the three Gauls (Henzen, 6393), the _adlector arcae Galliarum_, _inquisitor Galliarum_, _iudex arcae Galliarum_, no other province, so far as I know, furnishes analogies; and of these institutions, had they been general, the inscriptions elsewhere would certainly have preserved traces. These arrangements appear to point to a self-administering and self-taxing body (the _adlector_, the meaning of which term is not clear, occurs as an official in _collegia_, _C. I. L._ vi. 355; Orelli, 2406); probably this chest defrayed the doubtless not inconsiderable expenditure for the temple-buildings and for the annual festival. The _arca Galliarum_ was not a state-chest.] [48: As the total number of the communities recorded on the altar at Lyons, Strabo (iv. 3, 2, p. 192) specifies sixty, and as the number of the Aquitanian communities in the Celtic portion north of the Garonne fourteen (iv. 1, 1, p. 177). Tacitus (_Ann._ iii. 44) names as the total number of the Gallic cantons sixty-four, and so does, although in an incorrect connection, the scholiast on the _Aeneid_, i. 286. A like total number is pointed to by the list given in Ptolemy from the second century, which adduces for Aquitania seventeen, for the Lugudunensis twenty-five, for the Belgica twenty-two cantons. Of his Aquitanian cantons thirteen fall to the region between the Loire and Garonne, four to that between the Garonne and the Pyrenees. In the later one from the fifth century, which is well known under the name of _Notitia Galliarum_, twenty-six fall to Aquitania, twenty-four to the Lugudunensis (exclusive of Lyons), twenty-seven to Belgica. All these numbers are presumably correct, each for its time. Between the erection of the altar in 742 {12.} and the time of Tacitus (for to this his statement is doubtless to be referred), four cantons may have been added, just as the shifting of the numbers from the second to the fifth century may be referred to individual changes still in good part demonstrable.
