2.1 First fen dwellers
At the time when the ocean shores were mostly unpopulated, families had already taken possession of the inland waters. The nomad hunters of the Old Stone Age very often found their way barred by rivers large and small. They could halt upon the banks, fishing and pursuing the aquatic birds, but they wanted to cross the water in order to see what lay upon the other side. From Early  Palaeolithic  times  onward, therefore,  pioneers  used  tree trunks or bundles of branches for crossing wetlands.
By the Neolithic period people had command of cutting tools and of fire, and used them to hollow out the trunks of trees. Thus was born the canoe, that almost unsinkable vessel, ideal for river navigation and still used by millions in all the continents. It extended the range of settlement sites, for the family who owns and can paddle a canoe is able not only to go where he will upon most waterways but also, in case of need, to make its domicile on the islands and shores of lakes and rivers.
In 1853 the peasants owning fields alongside the lakes of Switzerland congratulated themselves upon an exceptionally dry winter; everywhere the low level of the water made it possible to encroach upon the lakes and increase the area of cultivated ground. Indeed an immemorial custom required them in such circumstances to dam the dried-up inlets and fill them with mud taken from the lake. In the spring of 1854 they set about their task, but in many places their work was impeded by strange obstacles, clusters of stakes driven into the lake bottom and forming a sort of palisade two or three hundred yards from the shore. The stakes were stout and from six to a dozen feet in length. To remove them would have taken time and required heavy toil. So they confined themselves to removing the mud between the stakes, which they wisely left alone.
They went down with their buckets, cursing the Romans for having stupidly barricaded 'their' lake. At first no one noticed that the mud contained implements of stone, wood and bone, and all were astonished when one of the workmen brought back in his pail things that looked like ornaments of bronze. Knowing that school- masters and museum officials were interested in Roman relics, the Swiss peasants informed them. Thus it came about, in March and April 1854, that the schools and municipal offices in the townships by the lakes of Zurich, Pfaffikon, Biel, Neuchatel and others were invaded by peasants who brought with them their miscellaneous collections.
Although Switzerland had no professional archaeologists at that time, some of the amateurs were quick to realize that these objects were not Roman. As Johannes Aeppli, schoolmaster at Obermeilen on Lake Zurich, declared, 'They must come from the most ancient inhabitants of our country.' Inspired by curiosity, Aeppli the schoolmaster, Ferdinand Keller, teacher of English, Friedrich Schwab, a town councillor of Biel, the notary Emanuel Muller-Haller and several other local notabilities came to inspect the newly discovered palisades. They engaged workmen to rake the bed of the lake with shovels, dredges, tongs and cramps; each clod of mud was broken to pieces. At the end of some weeks the harvest was impressive: stone and bronze axes, graving-tools, knives, daggers of hardened wood, spoons, needles, awls of horn and bone, potsherds, vestiges of cloth, of nets, of baskets and mats, the bones of wild and of domestic animals, piles of grain, nuts and apples. This was proof that the stakes driven into the mud were the supports of platforms upon which prehistoric men had built their dwellings.
The discovery caused a stir, for its magnitude exceeded that of any other collection of prehistoric finds. The Swiss lakes had provided the prehistorian with tools, arms, household utensils, skulls, bones, and had enabled the world for the first time to envisage the homes and daily life of a community in the distant past. Keller and Schwab—after the discoveries in Lake Zurich and Lake Neuchatel they had resigned their posts in order to devote themselves to prehistory—recalled that there were villages on piles in Indonesia, New Guinea and some parts of central Africa. To protect themselves, their families and their property against wild beasts and attack by enemies, the inhabitants erected platforms over water or marsh. Everything showed that the construction of the lakeside villages of Switzerland had been dictated by similar requirements.
A selection of objects taken from the Swiss lakes was placed on view in Paris during the Universal Exhibition of 1867. It gave the general public an opportunity to acquaint itself with the relics of the lakeside dwellers, as well as with flint implements, sculptures and incised drawings of the Old Stone Age, newly found in France. All Europe was agog for prehistory. True, the precise antiquity of the lakeside villages was not known, but fresh discoveries followed —remains on the shores of Lake Constance, of the Bavarian lakes, of the marshes of Swabia, in eastern France, northern Italy and Austria. By the close of the exhibition the number of recorded lakeside settlements was exactly two hundred.
Thanks to the devoted labours of the Swiss prehistorians and museum officials, scale models of these villages on piles were soon available, showing how the huts, with walls of wattle and daub or split timbers, clay floors and thatched roofs, had been erected on platforms and how the occupants had lived and worked—grinding corn, making tools and pottery, spinning, weaving, preparing animal hides, cooking. Subsequent years of drought revealed the remains of more lake villages, and in 1927 one was even reconstructed on its original site at Unteruhldingen on the German side of Lake Constance. Narrow gangways or dikes linked the settlements to the shore and its stretch of fields won from the forest, in which the lake villagers had used stone axes for cutting down the trees. They grew barley, beans, flax and wheat, and kept oxen, pigs, goats and sheep. The discovery of traces of roomy cattle pens may indicate that the livestock spent the night in the safety of the village.
The accuracy of the reconstruction has been disputed; and not all the experts agree that the dwellings were built over water, contending rather that the piles and platforms supported the huts over spits of marshy ground. Undeniably, however, the people chose a watery environment for the settlements, many of which were continuously occupied for a long period.
The culture of the lake dwellers differed essentially from that of the food-gathering hunters. The inhabitants of the lakeside villages certainly continued to hunt, and they fished in the pools and gathered wild fruits; but they were first and foremost tillers of the soil and pastoralists. They lived, not in small family groups or clans, but in large village communities; it has been estimated that there were five thousand people in the one discovered on the shores of Lake Neuchatel. Their agricultural skills enabled them to produce and store enough grain to last from one harvest to the next; their cereals and some of their domesticated animals were not native to Europe. Nor would it have been possible to build those pile-dwellings without stable, steerable boats from which to drive the stakes into the mud and in which to transport the stones used for anchoring them. And when the hunting grounds close to the settlement had no more game, a flotilla of canoes could set out for the opposite shore.
Whence did these people come? At what period did they live? A few decades after the discovery of the Swiss lake villages it became possible to answer the second question: the oldest of them dated from Neolithic times, about 3000 B.C. But those lakeside settlements met so well the requirements of a farming population surrounded by forest-dwelling hunters that many of the sites were occupied into the Bronze Age and a few into Roman times. There is evidence of successive conflagrations, whether accidental or the result of attack by hostile neighbours, and of successive rebuilding. The way of life of the lake dwellers did not alter greatly, but later generations had horses, cultivated vines and fermented the pressed grapes in terracotta vessels.
The arrival of these alien immigrants around the bigger lakes of Europe is part of the larger story of the 'Neolithic Revolution' which prehistorians and archaeologists have patiently pieced together. While the scattered populations of Europe were still at Palaeolithic or Mesolithic stages of development, in the Near East a new way of life had developed from about 7000 B.C. : farming communities living in permanent villages. Their superior stone implements, especially axes, enabled them to clear and cultivate land for growing a variety of good crops and herding domesticated animals; their improved weapons made the hunting of game more rewarding. A supply of food in excess of immediate needs furthered the development of crafts and specialist craftsmen. These farmers flourished and, seeking new territories, penetrated slowly into south-east Europe with their Neolithic culture, some by way of the Danube Valley.
Although they could hardly have offered organized resistance, the indigenous people were probably hostile to the immigrants who settled in their hunting and fishing grounds; perhaps the natives regarded domesticated cattle as 'fair game', and raided the new settlements even if they did not often openly attack. But a village built out over marsh or water would give the farmers the twofold advantage of a good defensive site and no loss of hard-won cultivable land.
In time the older peoples were displaced or absorbed as the Neolithic culture spread across the whole of Europe. In time also, by similar stages, were introduced the use of metals, the wheel, sailing ships and many other new techniques originating in the Bronze Age river-valley civilizations of Mesopotamia and Egypt.
