The discovery of these piles excited general interest, an interest that was redoubled when similar discoveries revealed that all the lakes of Switzerland were dotted with stations that had been built long centuries before in the midst of the waters. Twenty such stations were made out on Lake Bienne, twenty-four on the Lake of Geneva, thirty on Lake Constance, forty-nine on that of Neuchâtel, and others, though not so many, on Lakes Sempach, Morat, Mooseedorf, and Pfeffikon. In fact more than two hundred Lake Stations are now known in Switzerland; and how many more may have completely disappeared?
There is really nothing to surprise us in the fact of buildings rising from the midst of waters. They are known in historic times; Herodotus relates that the inhabitants of pile dwellings on Lake Prasias successfully repelled the attacks of the Persians commanded by Megabasus. Alonzo de Ojeda, the companion of Amerigo Vespucci, speaks of a village consisting of twenty large houses built on piles in the midst of a lake, to which he gave the name of Venezuela in honor of Venice, his native town. We meet with pile dwellings in our own day in the Celebes, in New Guinea, in Java, at Mindanao, and in the Caroline Islands. Sir Richard Burton saw pile dwellings at Dahomey, Captain Cameron on the lakes of Central Africa, and the Bishop of Labuan tells us that the houses of the Dayaks are built on lofty platforms on the shores of rivers. The accounts of historians and travellers help us to understand alike the anode of construction of the Lake Stations and the kind of life led by their inhabitants.
The Lake dwellings of Switzerland may be assigned to three different periods. That of Chavannes, on Lake Bienne, belongs to the earliest type. The hatchets found are small, scarcely polished, and always of native rock, such as serpentine, diorite, or saussurite; the pottery is coarse, mixed with grains of sand or bits of quartz; the bottoms of the vases are thick, and no traces of ornamentation can be made out. The pile-dwellings of the second period, such as those of Locras and Latringen, show considerable progress; the hatchets, some of which are very large, are well made. Several of them are of nephrite, chloromelanite, and jade; and their number, as compared with those in minerals native to Switzerland, varies from five to eight per cent. Here and there in rare instances we find a few copper or bronze lamellae amongst the piles. The pottery is now of finer clay, better kneaded; and ornamentation, including chevrons, wolves’ teeth, and mammillated designs, is more common. The handle, however, is still a mere projection. The third period, which we may date from the transition from stone to bronze, is largely represented; copper weapons and tools are already numerous, and bronze is beginning to occur. The stone hatchets and hammers are skilfully pierced, and wooden or horn implements are often found. The vases are of various shapes, all provided with handles, and are covered with ornaments, some made with the fingers of the potter, others with the help of a twig or some fine string. On the other hand, there are no hatchets of foreign rock; commerce and intercourse with people at a distance had ceased, or at least become rarer. The tools are fixed into handles of stag horn, which are found in every stage of manufacture. The personal property of the Lake Dwellers included bead necklaces, pendants, buttons, needles, and horn combs. The teeth of animals served as amulets, and the bones that were of denser material than born were used as javelin- or arrow-heads. The arrows were generally of triangular shape and not barbed.[11]
The distance from the shore of the most ancient of the Lake dwellings varies from 131 to 298 feet. Gradually men began to take greater and greater precautions against danger, and the most recent stations are 656 to 984 feet from the banks of the lake. The piles of the Stone age are from eleven to twelve inches in diameter; those of the later epochs are smaller. They are pointed at the ends, and hardened by fire. When the piles had been driven into the bottom of the lake, a platform was laid on them solid enough to bear the weight of the buts. This platform was made of beams laid down horizontally, and bound together by interlaced branches. Two modes of construction can easily be distinguished. In one the platforms were upheld by numerous piles, ten yards long, firmly driven into the mud. This is how the Pfahlbauten, Palafittes, or pile dwellings situated in shallow waters were generally put together. In other cases it seemed easier to raise the soil round the piles, than to drive them into the hard rock which formed the bed of the lake. Care was then taken to consolidate them, and keep them in position with blocks of stone, clay, and tiers of piles. Keller gives to these latter the name of Packwerbauten, and other German archæologists call them Steinbergen.
The mean depth of the waters in those parts of the lakes formerly occupied by the pile dwellings is from thirteen to sixteen feet, and we can still make out the piles when the water is calm and clear. Worn though they may be, their tops still emerge at a height varying from one to three feet above the mud at the bottom of the lake. Their number was originally considerable, and it is estimated that there were forty thousand at Wangen, and a hundred thousand at Robenhausen. The area occupied by the stations varies considerably; according to Troyon, that at Wangen was seven hundred paces long by one hundred and twenty broad. Baron von Mayenfisch explored seventeen sites in the Lake of Constance, the area of which varies from three to four acres. At Inkwyl is a little artificial island about forty-eight feet in diameter. The Lake dwelling of Morges, which was still inhabited in the Bronze age, covers an area of twelve hundred feet long by a mean width of one hundred and fifty. It is, however, useless to enumerate the various calculations that have been made, as they are founded on nothing but more or less probable guesswork.
Excavations show that the buts that rose from the platforms were made of wattle and hurdle-work. In different places calcined and agglutinated fragments have been picked up, and pieces of clay which had served as facing. The house to which they had belonged had been destroyed by fire, and the clay, hardened in the flames, had resisted the disintegrating action of the water. On one side this clay is smooth, and on the other it still retains the marks of the interlaced branches, which had helped to form the inner walls. Some of these marks are so clear and regular that Troyon, noticing the way they curve, was able to assert that the buts were circular, and that they varied in diameter from ten to fifteen feet.
A recent discovery at Schussenreid (Wurtemberg) gives completeness to our knowledge of the Swiss Lake dwellings. In the midst of a peat-bog rises a but known as a Knüppelbau, which is supposed to date from the Stone age. It is of rectangular form, and is divided into two compartments communicating with each other by a foot-bridge consisting of three beams laid side by side. The floors of this but are made of rounded wood, and the walls of piles split in half. Excavations have brought to light several floors, one above the other, and divided by thick layers of clay. The rising of the level of the peat doubtless compelled the Lake Dweller to add by degrees to the height of his house.
The Proto-Helvetian race were well-developed men, and the bones that have been collected show that they were not at all wanting in symmetry of form or in cranial capacity. The crania found are distinctly dolichocephalous, and their owners had evidently attained to no small degree of culture and of technical skill. Judging from the length of the femora found, though it must be added that they are mostly those of women, the ancient Lake Dwellers were not so tall as the present inhabitants of Europe. The smallness of the handles of their weapons and tools points to the same conclusion.[12]
Though the importance and number of the discoveries made in Switzerland render it the classic land of Lake Stations, it is not the only country in which they have been found. They have been made out in the Lago Maggiore and in the lakes of Varèse, Peschiera, and Garda in Lombardy; in Lake Salpi in the Capitanata, and in other parts of Italy. Judging from the objects recovered from these stations, they belonged partly to the Stone and partly to the Bronze age.
The pile dwelling of Lagozza is one of the most interesting known to us. It forms a long square, facing due east, and covers an area of two thousand six hundred yards, now completely overgrown with peat six and a half feet thick. Amongst the posts still standing can be made out a number of half-burnt planks, which are probably the remains of the platform. One of the posts was still covered with bark, and it was easy to recognize the silver birch (Betula alba). Other posts consisted of the trunks of resinous trees, such as the Pinus picea, the Pinus sylvestris, and the larch, which now only grow in the lofty Alpine valleys. Amongst the industrial objects found in the Lagozza pile dwelling were polished stone hatchets, hammers, polishers of hard stone, knife-blades, flint scrapers, and seven or eight arrows with transverse cutting edges, a form rare in Italy.
