2.3 Notions about wetlands
Since Mesolithic times man had made his home, seasonally or permanently, by lakes which, besides fresh water, provided fish and waterfowl for food and reeds for thatching. Permanent villages of huts built on piles driven into the shallows were established, and their remains have been found by the edges of lakes or former lakes in northern Italy, southern Germany, Switzerland and elsewhere. But the quaking ground of marshes and bogs must always have been feared and avoided. The eeriness of such an environment can still be felt: the croaking of frogs and the calls of unidentifiable creatures, drifting patches of mist, and especially at night the elusive and mysterious lights of will o' the wisp (now generally attributed to the rise and combustion of marsh gas from the decomposition of organic matter) and the phosphorescent glow of certain fungi. Hence, and not surprisingly, the long-standing belief in ghosts, lost spirits, 'burning souls' and other preternatural beings haunting the dreaded ground and giving rise to many legends.
In A.D. 98 the historian Tacitus made a study of the various European races living beyond the frontiers of the Roman Empire. To this work, De origine, situ, moribus ac populis Germanorum, better known as De Germania, we turn as our earliest source for the history of northern and eastern Europe. Its information, however, is not always reliable. Tacitus, for whom the Empire from Augustus to Domitian represented all that is most degraded and degrading in human life, sketched a picture intended to provide his contemporaries less with a faithful image of Germania and its people than with a pattern of moral virtue and simplicity. In the eyes of Tacitus the ancient Germans were free, healthy and straightforward men living close to nature, the embodiment of virtues whose absence he regretted in his fellow-countrymen.
De Germania is nevertheless of first importance for the study of the protohistory of Europe; it contains much information about the way of life and beliefs of people of Celtic Iron Age culture, upon which few details are to be found elsewhere. Tacitus is the first historian to have described the part played by marshes in the religion and the jurisprudence of Germania.
According to Tacitus, every year the tribes living in what are now Denmark and north Germany made sacrifices of servants or slaves to Nerthus, goddess of spring and fertility; after cleaning the statue and chariot of the divinity the fettered victims were plunged into the waters of a marsh or lake. In other contexts Germanic law laid down two kinds of capital punishment: hanging for traitors and deserters, and drowning for those guilty of cowardice, rape or unnatural practices. Corpses found lately in bogs of northern and central Europe seem to confirm these particulars.
It is likely that similar discoveries have been made for centuries by those working the peat bogs. Not knowing the period at which death had occurred they would notify the priest or pastor, who would give Christian burial to the bodies. In 1835 human remains exhumed from the peat caught the attention of the prehistorians for the first time; it was realized that these remains had been preserved because the presence of tannic acid and exclusion of oxygen had prevented putrefaction.
Up to the present about one hundred and fifty corpses have been taken from the peat bogs of what was once Germania and from areas formerly populated by Celts and Baits. These anonymous victims had all met a violent end; most are naked, shackled and wearing a sort of garotte round the neck; sometimes the throat has been cut or the skull broken with some blunt weapon. A girl of about fourteen found in a bog in Schleswig-Holstein was wearing a bandage over her eyes and the left side of the head had been shaven; not far off lay a man, strangled with a twig of hazel. The most complete body was that of a man found in 1950 in the Tollund peat bog in Denmark; a leather noose was round his neck and he wore a leather cap and belt. His head has been carefully preserved, and examination of the body revealed the last meal of this Iron Age man to have been entirely vegetarian.
Specialists have long puzzled over these primitive killings, but no satisfactory explanation has yet been provided. Probably they are, as Tacitus reports, of executed criminals or victims sacrificed to the goddess Nerthus. Among other female bodies is that of a clothed woman fixed to the bottom with stakes; she was taken from a bog in Jutland.
It may readily be imagined that these places of execution filled later generations with terror, and it was only a few centuries ago that man began, very timidly at first, to turn marshes and bogs to account, to drain and clear and plant them. Such cultivation brought the settlers no more than momentary rewards. In various times and countries marshes have had a dubious reputation; vagabonds, delinquents, prisoners and others whom authority wished to segregate were sent there to hard labour.
In 1765 an edict of Frederick the Great declared the marshes of East Frisia a Prussian possession. Special commissioners installed there in the following decades twenty thousand paupers and 'social misfits'. These raw colonists were supposed to burn the vegetation, dig the ground and plant cereals. The experiment ended in fiasco. We know today that such a result was inevitable and that the practice of clearing land by burning brings with it the destruction of the soil. The wretched colonists entrusted with the clearance of the East Frisian marshes were forced, in order to survive, to become brigands and beggars. Only at the beginning of the nineteenth century was an end put to this disastrous situation.
At all periods sphagnum moss has been dried and used as fuel in areas devoid of timber, but it was not until the thirteenth and fourteenth centuries that a small country, poor in wood but rich in bog, marsh and lake, revealed to the world a large- scale technique of peat-cutting and its possible results. The Netherlands, formed very largely of river deltas, has much low-lying land and from remote times the coastal areas have been constantly threatened by the sea. From the twelfth to the fifteenth century the Dutch lost in this way one fifth of their territory. At all times the Dutch have been forced to struggle obstinately in order to conquer and then to hold their fields. Thus they achieved a rare mastery of agriculture, horticulture and the regeneration of waterlogged ground. They defended themselves by building dikes and embankments and by digging canals to facilitate the outflow of salt or brackish water, so injurious to cultivation. The water was raised by pumps worked by hand and then, from the seventeenth century, by the windmills whose outlines have become a part of the landscape. The Dutch took advantage also of their 'amphibian' situation, and became a nation of fishermen, sailors and traders. And as the resources of their country were limited, despite such efforts, they sought in the East and West Indies the riches which Holland could not provide.
But those measures did not suffice to replace the agricultural land lost to the sea, and so the peasants looked toward the moors. They cut the turf and sold it to the townsfolk for fuel, thereby increasing the danger; for the trenches and pits filled and created new stretches of standing water which could not drain away.
In the north-east they grappled with the problem differently. The floods of 1287 had claimed 50,000 victims in the area between the mouth of the Ems and the Zuider Zee; those of 1421 twice as many. So two centuries before Dutch overseas trade and colonization reached their zenith the people of Groningen 'occupied' their neighbouring wastelands. They excavated canals allowing ships access to the peat bogs, and as they had no desire to create new lakes and ponds but wanted, on the contrary, agricultural land, they linked together the extraction of the peat, land drainage and the growing of crops. First they made an intricate canal system, after which they could take up the peat without causing the trenches to fill with water. Then, when the layer of peat had been removed, the ground was divided among the settlers—with the obligation to develop it. The rules were strict: nothing might be burned, and it was compulsory to till and manure the soil, to keep the canals and runnels clean, and to plant hedges and trees as wind-breaks. The general adoption of such methods gradually changed the face of Holland.
The example of Groningen was copied by other districts with peat bogs to exploit. Villages grew up in the newly fertile areas. Sale of the turf provided the settlers with the capital needed for increasing the network of canals; ships plied upon the watercourses, fetching manures and taking away the dried peat and the produce of the harvests. The success stimulated similar undertakings in other districts.
The achievements of Dutch engineers in reclaiming their inundated coastal areas need no emphasis. But it is easy to forget that many of the prosperous, clean, attractive Dutch towns and villages, the green pasture lands with their cattle, the fields of tulips, the bright parks, have been largely won back from the former marshes. Rehabilitation of the waterlogged soil made the fortune and the cultural notions of this little country which has fought so valiantly and successfully against the encroachment of river and sea.
