(2) The second theory, already anticipated, sees in Gauls and Belgæ a tall, fair Celtic folk, speaking a Celtic language, and belonging to the race which stretched from Ireland to Asia Minor, from North Germany to the Po, and were masters of Teutonic tribes till they were driven by them from the region between Elbe and Rhine.[15] Some Belgic tribes claimed a Germanic ancestry,[16] but "German" was a word seldom used with precision, and in this case may not mean Teutonic. The fair hair of this people has made many suppose that they were akin to the Teutons. But fairness is relative, and the dark Romans may have called brown hair fair, while they occasionally distinguished between the "fair" Gauls and fairer Germans. Their institutions and their religions (_pace_ Professor Rh[^y]s) differed, and though they were so long in contact the names of their gods and priests are unlike.[17] Their languages, again, though of "Aryan" stock, differ more from each other than does Celtic from Italic, pointing to a long period of Italo-Celtic unity, before Italiotes and Celts separated, and Celts came in contact with Teutons.[18] The typical German differs in mental and moral qualities from the typical Celt. Contrast an east country Scot, descendant of Teutonic stock, with a West Highlander, and the difference leaps to the eyes. Celts and Germans of history differ, then, in relative fairness, character, religion, and language. The tall, blonde Teutonic type of the Row graves is dolichocephalic. Was the Celtic type (assuming that Broca's "Celts" were not true Celts) dolicho or brachy? Broca thinks the Belgæ or "Kymri" were dolichocephalic, but all must agree with him that the skulls are too few to generalise from. Celtic iron-age skulls in Britain are dolichocephalic, perhaps a recrudescence of the aboriginal type. Broca's "Kymric" skulls are mesocephalic; this he attributes to crossing with the short round-heads. The evidence is too scanty for generalisation, while the Walloons, perhaps descendants of the Belgæ, have a high index, and some Gauls of classical art are broad-headed.[19] Skulls of the British round barrows (early Celtic Bronze Age) are mainly broad, the best specimens showing affinity to Neolithic brachycephalic skulls from Grenelle (though their owners were 5 inches shorter), Selaigneaux, and Borreby.[20] Dr. Beddoe thinks that the narrow-skulled Belgæ on the whole reinforced the meso- or brachycephalic round barrow folk in Britain. Dr. Thurnam identifies the latter with the Belgæ (Broca's Kymri), and thinks that Gaulish skulls were round, with beetling brows.[21] Professors Ripley and Sergi, disregarding their difference in stature and higher cephalic index, identify them with the short Alpine race (Broca's Celts). This is negatived by Mr. Keane.[22] Might not both, however, have originally sprung from a common stock and reached Europe at different times?[23]
