Editors’ Preface

      To man, caves are the original shelters, sought since Palaeolithic times hundreds of thousands of years ago. To the adventurous amongst us, they are challenges to be explored, dark passages leading to unknown underground palaces and waterways, sometimes of amazing beauty. To the naturalists amongst us, they arouse our interest by their curious and unique life-forms, selected by the restrictive environments, and by their presence in areas of limestone country of outstanding beauty. Yet, as with other life, the plant and animal communities of caves form a cohesive and interacting collection of organisms, from bacteria to mammals, from lower to higher plants, depending on the varied local environments within the cave systems.

      Here, then, is an ideal subject for the New Naturalist, taking into account not only the living natural history of caves, but also their origin, habitat characteristics, and what they tell us of past times. Indeed, as well as their living content of caves, the sediments within them are often the graveyard of past denizens of caves, such as the hyaena, as well as the prey of cave carnivores; and, of course, these sediments reveal past habitation by man through the present of bones and tools. So we have a fourth dimension of time to add to the natural history of caves.

      It may be thought that cave communities would be one of the few remaining natural ecosystems surviving in the British Isles, protected by difficulty of access. As with other living communities more apparent and better known to us, this is not the case; they are perhaps more fragile than above ground communities, more easily disturbed and affected by man’s activities. To the natural historian the subject of caves demands a broad multidisciplinary approach. Dr Chapman has extensive experience of the many aspects of cave natural history. He has been able to integrate this variety, dealing with the essential geological and geomorphological background, the historical theme, and the natural history of caves, so presenting the naturalist with an outstanding and cohesive account of a unique and extraordinary ecosystem of wide interest.

       The Fascination of Caves

The lure of caves

      There is a curious fascination about caves that seems to affect people of all ages and all cultures. Even as children, we have a kind of longing for caves, seeing them perhaps as a place of safety, but equally as a source of adventure and excitement – a gateway to the unknown.

      Our remote ancestors used the entrances of caves as habitations, but reserved their depths as hiding places for their most precious and powerful secrets – the painted, magical symbols which would ensure a continuing supply of game for hunting, and the earthly remains of their dead. Religion was born in caves, and even now the buildings of our Christian cultures retain atavisms of those earlier forms of worship; under the central part of the church lies the crypt, secret and dark – originally the burial place of saints and martyrs. It is perhaps also significant that the Mother of God should have appeared to Bernadette in a grotto at Lourdes, and should have consecrated the cave spring which welled up from underground.

      In Japanese mythology the sun-goddess Amaterasu retreated at night to a cave, plunging the world into darkness. The ancient Greeks too gave prominence to caves in their mythology. Zeus, chief of Gods, was born in a cave, and of course the Greek hell lay below ground, and at its gates Charon the ferryman waited in his boat to row the souls of the departed across the black waters of the River Styx into a land of grief and eternal pain. In our own mythology, King Arthur, his knights and hounds are said to slumber still beneath a Welsh mountain, eternally awaiting the call to battle. Even today in parts of New Guinea, tribesmen will say that their ancestors were born directly from the earth through the womb-like opening of a cave.

      With such a long cultural association between the darkness of caves, their chill and smell of decay, and the nameless terrors of the grave, it is not surprising that our ancestors should have equated caves with what they knew of volcanic vents and imagined the fires of hell in their depths. Dante’s Inferno is just one manifestation of an older oral tradition in Europe which told of animals, usually a dog or a goose, entering a cave to emerge days later from another miles away, devoid of fur or feathers and showing signs of singeing by infernal flames.

      Lurid accounts of real caves are frequent in ancient literature. The Roman philosopher Seneca reported that a party of Greek silver prospectors who ventured underground had encountered:

      “huge rushing rivers, vast still lakes, and spectacles fit to make them shake with horror. The land hung above their heads and the winds whistled hollowly in the shadows. In the depths, the frightful rivers led nowhere into the perpetual and alien night.”

      Seneca adds that after their return to the surface, the miners “lived in fear for having tempted the fires of Hell.”

      Perhaps the oldest written reference to a cave appears in a book about mountains written before 221 B.C. in China – a country where caves have been systematically explored and exploited over many centuries as water supplies and as sources of nitrates for fertilizer and for making gunpowder. The earliest surviving reference to a cave in Britain dates from around 200 A.D. in the writings of Titus Flavius Clemens, known as Clement of Alexandria. He writes:

      “Such as have composed histories concerning the Britannic islands tell of a cavern beneath a mountain, and at the summit of it a cleft, and of how from the wind rushing into this cavern and reverberating from its hollows, an echo as of many cymbals is heard.”

      Which cave this refers to is uncertain, but a location in either the Mendip Hills or Derbyshire would seem most likely since both areas were well-known as important centres of lead mining during this period. Current opinion favours the Great Cave of Wookey Hole which would undoubtedly have been known in Roman Britain and where, according to Balch (1929), a noise like the clash of cymbals can occasionally be heard.

      Irish caves were also documented from the earliest times. The Annals of the Four Masters, written in 928 A.D., record the massacre of 1000 people in Dunmore Cave in County Kilkenny and if the abundant remains excavated there are anything to go by, the account may well be true.

      The myth of the ‘howling cave’ resurfaces with Henry of Huntingdon in his mediaeval Historia Anglorum, written in Latin around 1135. He gives pride of place among the four “wonders of England” to a cave “from which the winds issue with great violence”. This one appears to have been situated in the Peak District and may have been Peak Cavern, since some time later Gervase of Tilbury, writing about this cave around 1211, states that strong winds sometimes blow out of it. The third of Huntingdon’s four wonders was also a cave, this time one situated at:

      “Chederole where there is a cavity under the earth which many have often entered and where, although they have traversed great expanses of earth and rivers, they could never come to the end.”

      This poses modern scholars with an interesting puzzle, for although there is indeed a well-known cave at Cheddar (open to the public as ‘Gough’s Cave’), it is short, easily explored and does not connect with the underground river known to flow beneath it.
