It is highly interesting to trace under Montelius’ guidance the development of culture as it seems to have actually taken place in southern Sweden. Beginning with the earliest periods, we find the coastal regions inhabited by a population of fishermen and hunters. At a subsequent stage coarse pottery appears with articles of bone and antler, and there is evidence that the dog has become domesticated. In the later Neolithic era perfectly polished stone hammers and exquisitely chipped flint implements occur, together with indications that cattle, horses, sheep and pigs are domesticated and that the cultivation of the soil has begun. Roughly speaking, we may assume that the culture of Scandinavia at the end of the Stone Age resembled in advancement that of the agricultural North American and Polynesian tribes as found by the first European explorers. We may assume a long period of essentially indigenous cultural growth followed towards its close by intimate relations with alien populations. Nevertheless, it was the more extensive contact of the Bronze period that rapidly raised the ancestral Swedes to a cultural position high above a primitive level, with accentuation of agriculture, the use of woolen clothing, and a knowledge of metallurgy. It was again foreign influence that later brought the knowledge of iron and in the third century of our era transformed the Scandinavians into a literary people, flooded their country with art products of the highest then existing Roman civilization, and ultimately introduced Christianity. The case of Scandinavian culture is fairly typical. We have first a long-continued course of leisurely and relatively undisturbed development, which is superseded by a tremendously rapid assimilation of cultural elements from without. Through contact with tribes possessing a higher civilization the ancient Scandinavians came to participate in its benefits and even to excel in special departments of it, such as bronze work, which from lack of material, they would have been physically incapable of developing unaided. Diffusion was the determinant of Scandinavian cultural progress from savagery to civilization. It is obvious that this insistence on contact of peoples as a condition of cultural evolution does not solve the ultimate problem of the origin of culture. The question naturally obtrudes itself: If the Scandinavians obtained their civilization from the Southeast, how did the Oriental cultures themselves originate? Nevertheless, when we examine these higher civilizations of the Old World, we are again met with indubitable evidence that one of the conditions of development is the contact of peoples and the consequent diffusion of cultural elements. This appears clearly from a consideration of the ancient civilizations of Egypt, Babylonia, and China.
