The situation was very favorable, with loess-clad hills sloping to rich meadows, and the lake furnishing fish and a line of communication. The areas occupied by the houses and stalls were clearly marked by the dark “culture-earth” contrasting sharply with the yellow loess. The principal house was rectangular. The outer wall was composed of posts with a wattling of twigs. This was plastered with clay, mixed with chaff and straw. The inner face of the wall was smoothly finished, and then “kalsomined” reddish yellow, and still further decorated with fresco in geometrical designs. The house—5.80 metres by 5.35 metres—was divided into two rooms. The larger part of the house was occupied by the kitchen, with its floor about one metre below the surface of the ground, and entered by an inclined plane or ramp. The other chamber, the sleeping-room, was nearly a metre above the kitchen and separated from it by a partition. Benches cut out of the loess were found in both kitchen and sleeping-room. Stalls for cattle and barns or granaries were also found. Virchow, in his review of Schliz’s monograph, emphasizes the fact that apparently Grosgartach was deserted by its inhabitants and fell into decay without leaving any signs of destruction by fire or violence.
The villages of Butmir, Lengyel, Jablanica, and others in southeastern Europe show us a condition of advanced culture here also.[44] Déchelette, speaking of the culture of this region, notices “the striking analogies between these old walled villages of the Balkans and the Danube valley, and those of the Ægean villages of the Troad and Phrygia.” Primitive idols, painted pottery, frequent use of the spiral in decorative art, all these reappear here and there in the Neolithic stations of southeastern Europe, and in the eastern basin of the Mediterranean in pre-Mycenæan and Mycenæan days. Evidently houses, settlements, modes of life, and stages of culture differ greatly during the same epoch of the Neolithic period in different parts of Europe. Italy was always far in advance of Europe north of the Alps. But even in northern Europe there was great diversity. Shell-heap dwellers still remained long after a much higher culture prevailed throughout most of Denmark. The life and thought of the pioneer hunters of northern Germany, and still more of northern Russia, were very different from those of the agriculturists along the valley of the Danube and in the Balkan Peninsula. In Greece little city-states began to arise early. Even in northern Europe density of population and size of settlements varied greatly. One illustration of these differences can be seen in the occurrence of fortified villages and refuges.[45] The age of these fortifications is as great a problem as that of the remains found in a pit-dwelling. The village may be, probably usually is, much older than the surrounding wall, and an earthen wall may contain Neolithic or even perhaps Paleolithic implements. The custom of fortifying villages evidently spread rapidly during the Bronze and Iron periods. Sophus Müller tells us that all walled settlements north of the Alps are far younger than the Neolithic period.[46] This statement, often disputed or neglected, is probably an exaggeration, but may well be true of the region surrounding the Baltic. The sparse and scattered hunting and pioneer population of Scandinavia and Germany had no need of building permanent walls around their single houses or small villages. They had very little wealth to protect.
But an agricultural population inhabiting a fertile region open to attack might well surround their villages with a wall, or provide a burg, or fortified place or “refuge,” whither they might drive their cattle or transport their grain. Examples of this are Stutzheim and Urmitz, in the Rhine valley, always a great thoroughfare, and in Switzerland and along the maritime Alps villages of this sort seem to have been fairly frequent. Apparently they were still more numerous in the valley of the Danube and in the Balkan Peninsula. It is not at all surprising to find them in Thessaly, so near to the advanced civilization of Greece.
Another class of settlements usually well protected were the workshops (ateliers) and manufacturing villages, especially those where flint was mined, or where flint implements were made in large quantities and distributed by trade over wide areas.[47] During the Neolithic period these settlements would have held much the same place and importance as our centres of coal, iron, manufacturing, and business have with us to-day. Grand Pressigny and Camp de Chassey, in France, and Cissbury, in England, are single examples of a great number of such fortified mining and manufacturing villages. For a further study of these very interesting remains the reader is referred to the manuals of Déchelette and Hoernes.
Even before the close of the Paleolithic period tundra and steppe were giving place to forests, which were advancing even into Scandinavia. The forest looms large and terrible in the works of classical writers and German antiquarians. Says Tacitus: “Who would leave the softer climes of Asia, Africa, or Italy to fix his abode in Germany, where Nature offers nothing but scenes of ugliness, where the inclemency of the seasons never relents?... The face of the country, though in some parts varied, presents a cheerless scene, covered with the gloom of forests, or deformed with wide-extended marshes.” He says that the soil produces grain and is well stocked with cattle, though of small size. But grain does not grow in primeval forests, and herds of cattle need at least open glades for pasturage. It is an extreme picture tinged by the homesickness of a citizen of sunny Italy. Northern Europe was generally heavily forested until long after Tacitus’s time. The Romans began in earnest the work of deforesting France, and the work was carried on all over Europe in mediæval times. The Neolithic immigrants probably made small clearings with the aid of fire, especially where the trees were low and not too thick, as on many light-soiled areas. They could make but little impression on the heavy forest growth, though they could limit its spread. They probably did not need to make wide clearings of dense forest. There were many open stretches of country of greater or less extent awaiting occupants and culture. This was true especially of districts occupied by the loess, whose origin from dust drifted by Paleolithic wind-storms we have already noticed.
Geikie describes loess as typically a “fine-grained, yellowish, calcareous, sandy loam, consisting very largely of minute grains of quartz with some admixture of argillaceous and calcareous matter.”[48] It is for the most part a wind-blown deposit. It is widely developed over low-lying regions, but sweeps up to heights of 200 to 300 feet and more above the bottoms of the great river valleys. Again, in many places we find it heaped up under the lee of hills, the exposed windward slopes of which bear no trace of it. Wherever there is loess we are likely to find the remains of steppe plants and animals. The ancient steppe area which generally covers, and probably extends considerably beyond, the loess district, is the region occupied by most of the primitive settlements. Even to-day it is less wooded than the rest of northern Europe. Such steppe regions in the North German plain are the great diluvial river terraces, especially the terraces of the Saale and Elbe and the eastern edge of the Harz Mountains; in South Germany the lower Alpine “Vorland” from Switzerland to lower Austria, the uplands of Suabia and Franconia, the valleys of the Main and Neckar, and much of northern Bohemia. These steppe regions of Germany, northern Austria, and Switzerland extended southeastward in a zone following the Danube, widening out in the great Hungarian plain into the vast steppe region extending eastward from the Black Sea or Pontus. From this Pontic steppe a band of more or less open country extended northward along the Carpathians until it almost or quite joined the open regions of the Elbe and along the Harz. A farther extension of this same band seems to have opened the way from the Harz region through northwest Germany into Belgium and northern France, and very probably into Brittany. We see at once the importance of these long lines of open or thinly forested country to the immigrations and settlement of Neolithic peoples. Periodical floods or other conditions kept open many river valleys, whose importance we shall estimate in a later chapter. All this land, except the uplands of Suabia and Franconia, and some similar areas, was comparatively fertile, the loess areas particularly so, and suited to a primitive agriculture.
In England the valleys of the Thames and other rivers were heavily wooded and not populated until much later. But the long lines of chalk-downs and oolitic uplands were far less favorable to forest growth. In Norfolk and Suffolk there were apparently open spaces. Yorkshire and Derbyshire had very similar landscapes. The forest was held back wherever the porous chalk formation made a large outcrop. In these places man could settle and find pasturage for his flocks and attempt a poor sort of agriculture, even in Neolithic days. Hence we find these regions dotted with Neolithic settlements. The immigrants who came in during the Bronze period settled in the same regions. Here again clearing of the forest on any large scale was apparently not attempted until Roman times, but along its boundaries, where the forest growth was not too heavy, these primitive agriculturists may well have cut off the lighter growth for fuel and buildings, and thus have gradually appreciably extended the arable area.
