It was not until later, driven to do so by the cold, that man learnt to use the natural caves hollowed out in limestone rocks, either in geological convulsions or by the quieter action of water. The absence in the caves which have been excavated in America of implements of the Chelléen type, the most ancient known as yet, would point to this conclusion, though it is impossible to fix the earliest date of their occupation. This date, moreover, varies very much in different localities. The earth was but gradually peopled, and our ancestors penetrated into different countries in successive migrations. Some caves have recently been discovered in Wales, in the midst of Glacial deposits.[2] The Boulder Clay and marine drift on neighboring heights are incontrovertible proofs of the submergence of this region, when Great Britain was almost completely covered with ice. Excavations made in 1886 have brought to light a series of deposits, one above the other, the gravel and red earth containing Quaternary bones and worked flints, whilst the stalagmite and ooze are evidently of more recent origin. This is the usual state of things in all the English eaves; but in those of the Clyde, the bone beds had been disturbed and mixed with striated pebbles and Glacial drift. From this Hicks, who superintended the excavations, concluded that man and the Quaternary animals had lived in those caves before the Glacial epoch, and before the great submergence, which in some places was no less than some 1,300 feet below the present level of the sea. If this were so, it would be one of the most ancient proofs not only of the presence of man, but also of the kind of habitation he first dwelt in. These conclusions have, however, been hotly disputed. M. Arcelin[3] remarks that there are in England two exceptional geological landmarks, the Forest Bed representing the last Pliocene formations, and the River Gravels, which are the most ancient Quaternary deposits. Between the two, we find the Boulder Clay of Glacial origin. Now the fauna of the caves of the Clyde, far from resembling that of the Forest Bed, appears to be more recent than that of the ancient deposits of the River Gravels. Amongst this fauna we find neither the Elephas antiquus nor the Rhinoceros Merckii; the worked flints are not like those known as belonging to the River-Gravel type, but the relics more nearly resemble those of the Reindeer period of France. It is therefore impossible, in the present state of our knowledge, to assert that man lived in the southwest of England in the Glacial epoch, to the phenomena of which, if he witnessed them, he must eventually have fallen a victim.
Our ancestors must constantly have disputed the possession of their caves of refuge with animals, but there is often a certain distinction between those chiefly occupied by man and the mere dens of wild beasts. The latter are generally more difficult of access, and are only to be entered by long, low, narrow, dark passages. Those permanently inhabited by man are wide, not very deep, and they are well lighted. That at Montgaudier, for instance, has an arched entrance some forty-five feet wide by eighteen high. The cave-men had already learnt to appreciate the advantages of air and light.
The caves are often of considerable height; that of Massat is some 560 feet high, that of Lherm is 655, that of Bouicheta nearly 755, that of Loubens 820, and that of Santhenay is, as much as 1,344 feet high. Those of Eyziès, Moustier, and Aurignac are also very lofty. As the valleys were hollowed out by the rushing torrents of the Quaternary floods, men sought a home near the waters which were indispensable to their existence, and came to dwell on the shores of rivers. The most ancient of the inhabited caves, therefore, are those on the highest levels, but the difference in the nature of the country and the varying force of geological action have led to so many exceptions, that all we can say with any certainty is that the caves were inhabited at different epochs. That of Montgaudier, for instance, was filled with an accumulation of ooze about forty feet thick. Weapons and tools lay one above the other from the bottom to the top, and it is easy to distinguish the succession of hearths by the blackened earth, cinders, charcoal, and crushed bones lying about them.
In the Placard Cave eight different deposits bear witness to the presence of man; and these are separated by others bare of traces of human occupation. The lowest deposit, which is some twenty-five feet below the present level of the soil, contains worked flints of the Moustérien type, above which, but separated by an accumulation of débris which has fallen from the roof, comes a layer in which was found a number of arrow-heads of the shape of laurel leaves. The fauna of both these levels includes the reindeer, the horse, and the aurochs. As we go up we find, above another layer of débris, the Solutréen type of tools and weapons represented by bone implements and numerous arrow-heads, this time stalked and notched. The four following levels correspond with those belonging to what is known as the Madeleine type, and the arrow-heads are decorated with geometrical designs. The traces of human occupation at different times, doubtless separated by long intervals, are therefore very clearly defined. The Fontabert Cave, in Dauphiné, contained, at a depth of about six feet, traces of fire and roughly worked flints, and about three feet below the surface lay the skeleton of a man, who had perhaps been overtaken by a fall of earth, still holding in his hand a polished dipper of fine workmanship. Yet a third and evidently more recent period is characterized by a jade crescent. We might easily multiply instances of a similar kind, but that we wish to avoid so much repetition.
We soon begin to find evidence of the progress made by man, and though in Neolithic times he still continued to occupy caves he learned to adapt them better to his needs. The rock shelters of the Petit-Morin valley, so well explored by M. de Baye, are the best examples we can give.
These caves are hollowed out of a very thick belt of cretaceous limestone. They date from different epochs, and each presents special characteristics which can easily be recognized. Some were used as burial-places, others as habitations. In the former the entrance is of irregular shape, the walls are roughly cut, and the work is of the most elementary description. The sepulchral eaves were simply closed by a large stone rolled into place and covered with rubbish, the better to hide the entrance. The shelters used to live in show much more careful work, and are divided into two unequal parts by a wall cut in the living rock. To get into the second partition one has to go down steps, cut in the limestone, and these steps are worn with long usage. The entrance was cut out of a massive piece of rock, left thick on purpose, and on either side of the opening the edges still show the rabbet which was to receive the door. Two small holes on the right and left were probably used to fix a bar across the front to strengthen the entrance. A good many of these eaves are provided with an opening for ventilation, and some skilful contrivances were resorted to for keeping out water. Inside we find different floors, shelves, and crockets cut in the chalk, and on the floors M. de Baye picked up shells, ornaments, and flints, which were lying just where their owners had left them. Very different is all this from the Vezère caves, and everything proves an undeniable improvement in the conditions of life.
The most interesting of all the objects found in these caves are, however, the carvings; but few date from Neolithic times, and some archæologists have argued from their absence in favor of the displacement everywhere of old races by the incursion of new-corners. Some of these carvings represent hafted hatchets, the flint being painted black to make the raised design stand out better. Others represent human figures. In the Coizard Cave, for instance, was found a roughly outlined representation of a woman with a prominent nose, eyes indicated by black dots, highly developed breasts, but no lower limbs. A necklace adorns her throat, and a pendant hanging from this necklace is colored yellow. On the passage leading to the door is engraved another figure which was originally more accurately drawn than the others, but is not in such good preservation. In the Courjonnet Cave we see a woman with a bird’s bead; she was probably one of the lares penates, the protectors of the domestic hearth. We meet with this same goddess at Santorin, and at Troy, and on the shores of the Vistula, which is a very interesting ethnological fact.
The objects found in the sepulchral caves are important, and included a number of arrow-heads with transverse cutting edges. There is no doubt about their use; they have been picked up in black earth, in contact with human bones, the decomposition of the soft parts of which caused them to fall out of the mortal wound they had inflicted. With these arrow-heads were found flint knives, large sloped scrapers, polishers, and bone stilettos, the femora of a ruminant with a pig’s tooth fixed on to each end, hoes made of stag horn, beads and pendants made of bone, shell, schist, quartz, and aragonite, with the teeth of bears, boars, wolves, and foxes, all pierced with holes. Some of the shell anti schist beads were spread upon the surface of the skull, and perhaps formed a net or résille, such as that already referred to as found at Baoussé-Roussé.
