Cairns, and Barrows in which such objects are found, were conceived to have been partly places of sacrifice, partly temples and seats of justice. But when amidst the vast mass of antiquities of stone which had been gradually collected, several shewed obvious marks of having been much used and worn, doubts began to be entertained whether they really had been employed as instruments of sacrifice. At length attention was directed to the fact that even at the present day, in several of the islands of the South seas and in other parts, there exist races of savages who, without knowing the use of metals, employ implements of stone which have the same shape and adaptation as those which are discovered in the earth in such quantities in Denmark, and further, it was shewn in what manner those savages made use of such simple and apparently such useless implements. No one after this could longer remain in doubt that our antiquities of stone were also actually used as tools in times when metals were either unknown, or were so rare and costly, that they were only in the possession of very few individuals. That this could not have been the case in this country while inhabited by our forefathers the Goths, is evident from all historical records, we must therefore seek for the origin of the antiquities of stone in an earlier time, in fact, as we shall soon perceive, among the first inhabitants of our native land.
As soon as it was once pointed out that the whole of these antiquities could by no means be referred to one and the same period, people began to see more clearly the difference between them. We are now enabled to pronounce with certainty, that our antiquities belonging to the times of paganism may be referred to three chief classes, referable to three distinct periods. The first class includes all antiquarian objects formed of stone, respecting which we must assume that they appertain to the stone-period, as it is called, that is, to a period when the use of metals was in a great measure unknown. The second class comprises the oldest metallic objects; these however were not as yet composed of iron, but of a peculiar
