If we look at the numerous local, national, and individual names of the Belgæ, we find that they agree so closely in form with those of the undoubted Gauls, as to be wholly undistinguishable. The towns end in -_acum_, -_briva_, -_magus_, -_dunum_, and -_durum_, and begin with _Ver_-, _Cær_-, _Con_-, and _Tre_-, just like those of Central Gallia; so that we have--to go no farther than the common maps--Viriovi-_acum_, Minori-_acum_, Origi-_acum_, Turn-_acum_, Bag-_acum_, Camar-_acum_, Nemet-_acum_, Catusi-_acum_, Gemini-_acum_, Blari-_acum_, Mederi-_acum_, Tolbi-_acum_; Samaro-_briva_; Novio-_magus_, Moso-_magus_; Vero-_dunum_; Marco-_durum_, Theo-_durum_; _Ver_-omandui; _Cær_-asi; _Con_-drusi; _Tre_-viri--all Gallic compounds on Belgian ground, and all forms either wholly foreign to any German area, or else exceedingly rare. Now it is no objection to this remarkable and exclusive preponderance of Gallic names in Belgian geography, to say that there is no proof of the designations in question being native; and that, although they existed in the language of Cæsar's informants, who were Gauls, they were strange to the Belgæ, even as the word _Welsh_ is strange to a Cambro-Briton--being the name by which he is known to an Englishman, but not the true and native denomination. I say that all argument of this kind, valid as it is in so many other cases where it is never applied, has no place here; since Cæsar's informants about the Belgic populations were the Belgæ themselves, and it is inconceivable that they should have used nothing but Gallic terms when they spoke of themselves, if they had not been Gauls. The names of the individual Belgic chiefs are as Gallic as those of the towns and nations, _e.g._, _Commius_ and _Divitiacus_, and so are those of such Britons as _Cassibelaunus_. I submit that this is, as far as it goes, a reason for limiting rather than extending all such statements as the ones in question. And it is by no means a solitary one. A statement of Strabo confirms it:--"The Aquitanians are wholly different" (_i.e._, from the other Gauls) "not only in language, but in their bodies,--wherein they are more like the Iberians than the Gauls. The rest are Gallic in look; but not all alike in language. Some differ _a little_. Their politics, too, and manners of life differ _a little_."--Lib. iv. c. 1. With the external evidence, then, of Strabo, coinciding with the internal evidence derived from the geographical, national, and individual names, it seems illegitimate to infer from the text of Cæsar more than has been suggested.
