As it is impossible to attribute any longer these prehistoric monuments to the "Celts," or to "their priests, the Druids," so do others of our historical illusions vanish. M. Duruy, in his learned _Histoire de France_, states that at the dawn of history the country known as Gaul was "divided between three or four hundred tribes (_peuplades_) belonging to the three great families,--the Celts, the Iberians, and the Belgians." M. Guizot says that "in the south were Iberians or Aquitanians, Phœnicians and Greeks; in the north and northwest, Kymrians or Belgians; everywhere else, Gauls or Celts, the most numerous settlers, who had the honor of giving their name to the country." M. Salomon Reinach, in his detailed description of the monuments in the Museum of Saint-Germain-en-Laye, under the general title of _Antiquités nationales_, declines to recognize the _race celtique_; in accord with the science of anthropology he distinguishes various Gaulish types and is aware that they nowhere present themselves in a pure state. Professor Bertrand "superposes" upon his _Mégalithiques_, whose distinguishing trait in Europe is their use of polished stone, another race, numerically inferior and much less ancient; these are the "_tribus celtiques_ or _celtisées_ of the Aryan race." When they arrived in Gaul, they were already familiar with the use of metals, especially bronze, beginning to be acquainted with iron; they were pastoral and agricultural, and burned their dead. About the sixth century B.C. appeared a third group, the _tribus galatiques_, Helvetians, Kymrians, Belgians; they were wandering bands of warriors, who used iron implements only and buried their dead. "From the superposition, rather than from the fusion, of these divers elements has resulted that which is called _la nation gauloise_ or _celtique_."
