Let us stress again that the Folsom and Eden chipping reached a perfection unknown in Europe until neolithic man brought in agriculture. Indeed, if the paleolithic Solutrean points had never been found, _all_ American archaeologists—instead of just one or two—might unhesitatingly have called Folsom and Eden neolithic, even though they were found with extinct animals. In the history of Europe’s Old Stone Age—and in Africa’s, too, for that matter—we have no more than one hint of such work. It was only the men of the Solutrean culture—thrust between the late Aurignacian and the early Magdalenian—who took much true advantage of pressure flaking, and who made spear points with Sandia-like shoulders. (While the flint chipping of the Solutreans is fine, it is not so minute or so perfect as the work of the men who made Folsom and Eden points.) With the disappearance of the Solutreans, the art of fine flint knapping and point making faded away in the Old World, not to appear again with any vigor until neolithic times. The Solutreans are not a part of the flow and development of prehistoric European culture. They seem to come as invaders, and then fade out after 500 years, or, at the most, 10,000. Where they came from is uncertain. Because crude points called Proto-Solutrean are much more plentiful along the Danube than they are in France—where the finest Solutrean work is found—it has long been argued that the people who made them came from western Asia. Lately, flint work of the Solutrean type has been discovered in Morocco and also in Egypt;[7] and, since it is intermixed with the products of a much older culture, the Mousterian, it may be argued that the Solutreans came from Africa. The theory of an eastern origin remains strong, however; for among the African flints are shouldered points, and shouldered points were not developed until the end of the Solutrean period in Europe. We do not know the date of the Mousterian in Africa; it may have been late. If the Solutreans did, in fact, originate in Asia, can we believe that an Asiatic people with an unusual flair for flint knapping fathered both the Solutreans and the men who made the Sandia and the far finer Folsom and Eden points? Did this parent stock send a group of migrants across Bering Strait and down into the High Plains to give us Folsom, Sandia, and Eden points? Did it throw off toward the west a group that practiced the Solutrean arts in Europe? Even after archaeologists have dug Siberia thoroughly we may never know how much earlier or later the American offshoot appeared on the High Plains than the Solutreans in Europe.
