It is now generally recognised by archæologists that all people who have advanced to a certain degree of civilisation have passed through three periods of development, which according to the material of which their implements, weapons, and utensils were made, have been named the stone, the bronze, and the iron age. We have very abundant evidence that the people of the North passed through these three stages, and indeed had reached the iron age before they came within the ken of history. Beginning with the stone age, let us see what we can learn of the civilisation of the North from the various articles which were in use during the three stages.

The finds in the North have been classified under the name “grave,” “bog,” and “earthfinds; that is, objects found in graves, bogs, or in the ground. In the latter case they are often hidden under stones, in obedience to the injunctions of Odin. Those of the iron age are found as far as 69° North latitude.

The custom of burying different objects with the dead, and also that of throwing objects and weapons into springs or bogs, or of hiding them in the ground, has helped in a most remarkable manner to give us an idea of the industries and daily life of the people there at a remote period.

In the earliest age the use of metal was unknown, the weapons were made of stone, horn, and bone,[[110]] and towards the close of this age pottery was made.

The first traces of man in some parts of the present Scandinavia are the kjökkenmöddinger (kitchen refuse heaps), consisting of oyster and mussel shells, bones of fish, birds, and mammals, such as the deer, bear, boar, beaver, seal, ure-ox, wolf, fox, &c., &c., with remains of clay vessels. Among and near these heaps of refuse are found a great number of rude implements and weapons made of flint, bone, horn, and broken flint chips, also fireplaces made of a few stones roughly put together, thus showing that the inhabitants lived in a very primitive state.

No graves of the earliest period of the stone age have thus far been found in the North. Towards the latter part of this age we see a great improvement in the making of weapons and tools; the latter were beautifully polished, and graceful in form. Domestic animals had also been introduced, as shown by the bones of cattle, horses, sheep, pigs, and dogs, that have been found in the graves. Beads of amber and bone were worn as ornaments. The graves of the stone age discovered in the present Scandinavia and on the islands and shores of the Baltic may be classified in four groups: the cromlech or dolmen; the passage or gallery graves; the free-standing stone coffins; and the stone coffins covered by a mound.[[111]]

The cromlechs consist of from three to five large stones standing upright, and so placed as to form a ring, with a large block or boulder on the top. These were intended for a single body, buried in a sitting position, with flint implements and weapons. The walls of the chamber were made by large stones, smooth inside, and the floor consisted of sand or gravel. Certain marks on the tops of stones seem to indicate that sacrifices to the dead were prevalent; holes about 2 inches in width are found on the roofs of some cromlechs and passage graves. These cromlechs always occur near the sea, seldom more than seven miles from the coast. The other graves of the stone age are often found far inland, but they are almost always near a lake or river having connection with the sea.
