Considering the importance of these arrangements, it will not be superfluous to exhibit them in detail, at least for the two western provinces. In the purely Celtic middle province the three lists given by Pliny (first century), Ptolemy (second century), and the _Notitia_ (fifth century), agree in twenty-one names: _Abrincates_--_Andecavi_ --_Aulerci Cenomani_--_Aulerci Diablintes_--_Aulerci Eburovici_ --_Baiocasses_ (_Bodiocasses_ Plin., _Vadicasii_ Ptol.--_Carnutes_ --_Coriosolites_ (beyond doubt the _Samnitae_ of Ptolemy)--_Haedui_ --_Lexovii_--_Meldae_--_Namnetes_--_Osismii_--_Parisii_-- _Redones_--_Senones_--_Tricassini_--_Turones_--_Veliocasses_ (_Rotomagenses_)--_Veneti_--_Unelli_ (_Constantia_); in three more: _Caletae_--_Segusiavi_--_Viducasses_, Pliny and Ptolemy agree, while they are wanting in the _Notitia_, because in the meanwhile the _Caletae_ were put together with the Veliocasses or the Rotomagenses, the Viducasses with the Baiocasses, and the Segusiavi were merged in Lyons. On the other hand, instead of the three that have disappeared, there appear two new ones that have arisen by division: _Aureliani_ (Orleans), a branch from the _Carnutes_ (Chartres), and _Autessiodurum_ (Auxerre), a branch from the _Senones_ (Sens). There are left in Pliny two names, _Boi_--_Atesui_; in Ptolemy one, _Arvii_; in the _Notitia_ one, _Saii_. For Celtic Aquitania the three lists agree in eleven names: _Arverni_--_Bituriges Cubi_--_Bituriges Vivisci_ (_Burdigalenses_)--_Cadurci_--_Gabales_--_Lemovici_--_Nitiobriges_ (_Aginnenses_)--_Petrucorii_--_Pictones_--_Ruteni_--_Santones_; the second and third agree in the 12th of _Vellauni_, which must have dropped out in Pliny; Pliny alone has (apart from the problematic _Aquitani_) two names more, _Ambilatri_ and _Anagnutes_; Ptolemy one otherwise unknown, _Datii_; perhaps Strabo's number of fourteen is to be made up by two of these. The _Notitia_ has, besides these eleven, other two, based on splitting up the _Albigenses_ (Albi on the Tarn), and the _Ecolismenses_ (Angoulême). The lists of the eastern cantons stand related in a similar way. Although subordinate differences emerge, which cannot be here discussed, the character and the continuity of the Gallic cantonal division are clearly apparent.] [49: The four represented tribes were the Tarbelli, Vasates, Auscii, and Convenae. Besides these Pliny enumerates in southern Aquitania no less than twenty-five tribes--most of them otherwise unknown--as standing on a legal equality with those four.] [50: Pliny and, presumably here too following older sources of information, Ptolemy know nothing of this division; but we still possess the uncouth verses of the Gascon farmer (Borghesi, _Opp._ viii. 544), who effected this change in Rome, beyond doubt in company with a number of his countrymen, although he has preferred not to add that it was so:--
