Commerce developed rapidly during Neolithic times, and, as far as we can make out from traces left, its course was from the southeast to the northwest. Streams and rivers were followed by merchants as by emigrants, and at an extremely remote date the sea no longer arrested the journeys of men. At a recent meeting of the British Anthropological Inst.i.tute, Miss Buckland dwelt on the resemblance in the material, shape, and ornamentation of a golden cup found in , Cornwall, to other cups found at Mykenae and at Tarquinii, and maintained that the Cornish cup must have been the work of the same artisans, and have been brought by commerce from what was then the extremity of the known world.

It is not only in Europe that we can trace the relations established between men separated by vast distances, by oceans, and by apparently impa.s.sable deserts. The sh.e.l.ls of the Atlantic and those of the Pacific, the copper of Lake Superior, the mica of the Alleghanies, and the obsidian of Mexico lie together beneath the tumuli of Ohio, and quite recently Mr. Putnam exhibited to the Society of Antiquaries a collection of jade celts and ornaments, some from Nicaragua, others from Costa Rica, and a hatchet with both edges sharpened from Michigan. No deposit of jade has so far been discovered on the American continent, so that we can only suppose these objects to have been brought from Asia at an unknown date. The marks they retain of having been rubbed up, and the holes made in them to hang them. up, show what store was set by them.

Monuments of many kinds scattered over different countries, weapons and implements, relics as they are of a remote past, enable us to gain a closer insight into the manners, customs, and mode of life of our ancestors of the Stone age. We can picture their daily life, which we know to have been one long struggle, without break or truce, for they had to contend, not only with wild animals but with each other, to fight for the use of their caves of refuge, for their hunting fields, and for their watercourses; and later, the first shepherds had to do battle for the pasturage necessary for their flocks. It is only too certain that, from the earliest dawn of humanity, men gave way, without any effort at self-control, to their brutal pa.s.sions. The right of the strongest was the only law, and wherever man penetrated his course was marked by violence and by death. One of the femora of an old man was found in the celebrated Cro-Magnon Cave, bearing a deep depression caused by a blow of a projectile, and on the forehead of the woman that lay beside him is a large wound made by a small flint hatchet (Fig. 76). This gash on the frontal bone penetrated the skull, and was probably the cause of death, but not of sudden death, for round about the wound are marks of an attempt at healing it.[181]

According to Dr. Hamy, many of the bones found in the Sordes Cave have very curious wounds. A gaping hole on the right parietal of a woman must have been a terrible wound (Fig. 77). The woman of Sordes, like that of Cro-Magnon, must have survived for some time; the marks of the removal of splinters of bone, which can quite easily be made out, leave no doubt on that point.[182]

In the Baumes-Chaudes caves, situated in that part of the valley of the Tarn which belongs to the department of Lozere, Dr. Prunieres picked up numerous bones bearing scars, characteristic of wounds produced by stone weapons.[183] Some fifteen of these bones, such as the right and left hip bones, tibiae, and vertebrae, still contain flint points flung with sufficient force to penetrate deeply the bony tissue. Always indefatigable in his researches, Dr. Prunieres also mentions having found in the cave known as that of L'HOMME MORT bones bearing traces of cicatrized wounds, and he presented to the Scientific Congress at Clermont a human vertebra found beneath the Aumede dolmen pierced with an arrow-head, which is, so to speak, encased in the wound by the formation of bony tissue.

FIGURE 77

Of the nineteen crania found in the Neolithic sepulchre of Vaureal two show traces of old wounds. One of them, that of a woman, has three different scars, two of which were of wounds that had healed, whilst the third in the occiput was a gaping hole, which had evidently caused death.

A sepulchral cave at Nogent-les-Vierges (Oise) contains the skeleton of a man with a wound on the forehead, no less than four and a half inches long by three broad. This man, who was dune young, the sutures being still very apparent, survived this serious wound for some time.

The Gourdan Cave has yielded crania and jaws broken by blunt weapons, whilst on other crania have been made out scratches and stripes which could only have been produced after the hair and skin had been removed. In the caves of the Pet.i.t-Morin valley, M. de Baye picked up some human vertebra pierced with flints, the points of which were still imbedded in the bones. In the Villevenard Cave one skull was found containing three arrow-beads with transverse points imbedded in the skull, the bone of which had closed upon them. Another arrow was lodged between the dorsal vertebrae. It is probable that these arrows had remained in the wounds; certainly that is the simplest way to account for their position. About two miles from the caves of which we have been speaking, M. de Baye discovered a sepulchre containing thirty skeletons, all of adult and strongly built individuals. The bodies were laid one above the other, and separated by large flat stones and a thin layer of earth. This sepulchral cave contained seventy-three flint points. As in the case of Villevenard, their position leads us to suppose that these points had been sticking in the flesh of the bodies when they were interred, and had fallen out when decomposition set in. Probably the bodies were those of men who had fallen victims in a b.l.o.o.d.y conflict that had taken place in the valley. In a cave at the station of Oyes, was found stretched upon a bed of stones a skeleton with a piece of flint, which had been flung with great force, imbedded in the upper part of the humerus. Round about the wound are the marks of many attempts at healing it.

Many of the human bones found in the Vivarais Cave bear traces of having been violently fractured by stone weapons with tapering points. In the Challes Cave (Savoy) lies the skeleton of a woman whose skull was fractured by a flint weapon, but in this case death was evidently immediate, at least if we may judge from the fact that there are no signs of the wound having received any treatment. In the Castellet Cave, a human vertebra contained the weapon which had pierced it, but when the bone was touched the arrow-head broke off. It had, however, been flung with such a sure hand that it had been driven ten inches deep into the bony tissue. Here, too, the absence of any exostosis proves that death quickly followed the wound.

In other cases the victims seem to have lived for some time. We have already spoken of wounds in crania that had healed, and we may add that a few years ago a, human bone was presented to the Archaeological Society of Bordeaux which still retained a flint arrow-head in the wound it had made. Traces could clearly be made out of the inflammation caused by the presence of the foreign body, and the bony tissue secreted by the periosteum had, so to speak, taken the mould of the arrow (Fig. 78).

In the cave known as the Trou d'Argent (Ba.s.ses-Alpes) amongst the bones of ruminants and carnivora, fragments of pottery and rubbish of all kinds, was found a piece of humerus (Fig. 79) pierced at the elbow joint and very neatly cut at the lower end, no doubt with the help of some of the implements of hard rock scattered about the cave. The position of this human bone amongst the remains of animals and fragments of a meal, points to its being a relic of a scene of cannibalism; adding yet another proof to what I said at the beginning of this work.

Similar facts are reported front England and Germany. Dr. w.a.n.kel mentions an interesting prehistoric deposit at Prerau, near Olmutz, amongst the bones of animals belonging to the most ancient Quaternary fauna, such as the mammoth, the cave-bear, the cave-lion, the glutton, and the arctic fox; and amongst clumsy bone and ivory weapons and ornaments he found a human jaw and a femur covered with strip produced by flint hatchets. In 1801 Mr. Cunnington took several skeletons from a barrow near Heytesbury, the skull of one of which had been broken with a blunt implement; and Sir R. h.o.a.re speaks of a skull from the neighborhood of Stonehenge split open by a blow from one of these formidable weapons. Several crania taken from a long barrow at West Kennet have similar wounds.

Similar facts were noticed at Littleton-Drew, at Uley, at Cotswold, and at Rodmarten, and from this Dr. Thurmam concluded that nearly all those who were buried in long barrows had met with a violent death.[184] He speaks, however, of one skull pierced with a large hole, the edges of which had become rounded smooth, showing the action of a recuperative process, and proving that the injured man had long survived his serious wound. In 1809, a farmer of Kirkcudbrightshire set to work to demolish a large cairn that interfered with his tilling of the soil, and which, according to popular tradition, was the tomb of a Scotch king. In taking away the earth the workmen found a large stone coffin, in which lay the skeleton of a man of great stature. The arm had been almost separated from the trunk by the blow of a diorite hatchet, a broken bit of which remained imbedded in the bone.[185]

One of the few crania that can with certainty be said to have belonged to Lake Dwellers of Switzerland was found at Sutz, near Zurich; this skull was fractured at the back. The roundness of the wound, which had been serious enough to cause death, has led authorities to conclude that it was made with one of the formidable pick-hammers, so many of which were found in the lake of Bienne.[186] Nilsson speaks of a human cranium pierced with a flint arrow, and of another, both found at Tygelso (Scandinavia), containing a dart made out of the antler of an eland.[187] At Chauvaux, at Cesareda, and Gibraltar other crania have been found bearing the marks of mortal wounds, and if we cross the Atlantic we meet with similar instances. Lund tells us that at Lagoa do Sumidouro crania were found pierced with circular tools, whilst near them lay the implements that had caused death.[188] At Comox, in Vancouver Island, a skeleton was found with a flint knife imbedded in one of the bones, and at Madisonville (Ohio) another, one of the bones of which was pierced by a triangular stone arrow; whilst beneath a mound in Indiana was picked up a skull pierced by a flint arrow more than six inches long. Excavations at Copiapo (Chili) brought to light the skeleton of a man who had sustained no less than eight wounds from arrows. The force with which they must have been shot is really astonishing; one had broken the upper jaw and knocked out several teeth, penetrating to the brain; and others were still sticking in the vertebrae and ribs.[189]

In the New as in the Old World man survived many of these horrible wounds, and a skull found under a mound near Devil's River shows a serious wound inflicted many years before death, and one of the Peruvian crania in the Peabody Museum bears a long frontal fracture, doubtless produced by the violent blow of a club; the five or six fragments still to be made out are, so to speak, solidified, and the wounded man had evidently lived on for many years, thanks apparently to his good const.i.tution alone, for there are no signs of the performing of any surgical operation, such as the removal of the splinters of bone, for instance.[190]

In 1884 a human vertebra, with an arrow-head imbedded in it, was picked up on the island of Santa Cruz. The apophysis was broken, and the extent of the fracture shows the great force of the blow. The victim evidently died of the wound, for there is no sign of its having been healed.

I have dwelt upon these deaths and wounds in spite of the inevitable monotony of such a list, not because I wish to bring into prominence the fact that from the earliest times the struggle for existence was fierce and b.l.o.o.d.y, but because I am anxious to prove that in these remote days an organized and intelligent society had grown up. No one could have survived such wounds as we have described, but for the care and nursing of those around him, such as the other members of his family or of his tribe. The wounded one must have been fed by others for months; nay more, he must have been carried in migrations, and his food and resting-place must have been prepared for him. Moreover, and this is of even yet more importance to our argument, they must have been men able to treat wounds and to set bones.

This last fact has been proved beyond a doubt by the discovery of numerous bones with the old wounds completely cicatrized. "In several examples," says Dr. Prunieres, speaking in this connection, "we can make out the fractures set with a neatness which gives us a very high opinion of the skill of the Neolithic bone setters. The setting of one fracture at the lower end of the tibia and of another at the neck of the femur, are not inferior to what we should expect from the most skilful surgeons of the globe."[191] A remarkable fact truly, but one often met with in the most widely separated regions of the earth, the importance of which cannot be overrated, and justifies the giving of a few more details.

In 1873 Dr. Prunieres, to whom science has reason to be very grateful for his singular discovery, presented to the members of the French a.s.sociation, in session at Lyons, a human parietal with a rounded piece of bone let into it. This piece of bone was rather larger than a five-franc piece, and the skull into which it had been fixed was found beneath the Lozere dolmen. A large opening, some three inches in diameter, the edges of which were worn smooth, had been made in this skull, and the piece of bone let into it was thicker than the skull itself, as well as different in color, the cranium being dark and the foreign piece of bone pale yellow. It was evident therefore that the two pieces did not belong in life to one person, and that the rounded piece had been cut out of some other skull. The following year Dr. Prunieres added fresh details about other rounded pieces of skull that be had discovered let into crania, some of which pieces had evidently been introduced during the life of the patient, who had died under the operation of trepanation, whilst others had been put in after death. Dr. Prunieres in every case speaks of RONDELLES or rounded pieces of skulls, and we prefer to quote him exactly, but as a matter of fact the trepanation was sometimes done with elliptical, triangular, or even pyramidal pieces of bone.

Later no less than sixty fresh examples, corroborating Dr. Prunieres'

discoveries, were found in the Baumes-Chaudes caves, and Broca in his turn reported the finding of three crania in the cave of L'HOMME MORT, from which great pieces had been taken which had evidently not been lost by accident.

From this time excavations and discoveries made under Dr. Prunieres succeeded each other rapidly. In 1887 his collection contained 167 crania or fragments of crania, all perforated, 115 of which were picked up in the caves of Lozere, which are probably of more recent date, beneath the dolmens of the DEVEZES, as those vast plains given lip to pasturage are called. These dolmens, which were doubtless reserved for the burial of chiefs, often contain many valuable objects. Beneath one, for instance, were found fifteen beautiful darts of variegated flint, four polished boars' tusks, some schist pendants, some sh.e.l.ls cut into the shape of teeth, some bone and stone necklace beads, and, lastly, two small bronze beads. These last-named objects justify us in dating the dolmen from the Bronze epoch, when the use of bronze began to spread over the district, though it was still not generally employed.

Attention once awakened, similar facts began to be announced from many different quarters. In the Neolithic caves of Marne were found skulls with rounded holes in them, pieces of skull such as are shown in Fig. 28, which were probably worn as amulets. M. de Baye has in his fine collection more than twenty examples of trepanation, one of. which is shown in Fig. 80. In nearly every case the operation had been performed after death; three examples alone show it to have been done during life, and that the patient certainly survived, for the wound shows very evident signs of having healed, and the edges of the openings no longer bear the marks of the tool of the operator. On one of the three crania there were two wounds near each other, but they were quite separate, and were evidently not treated at the same time.

FIGURE 80

A tumulus in the Guisseny commune (Finistere), excavated about two years ago, covered over a sepulchral crypt. At the southeastern extremity was picked up a badly baked hand-made earthenware vase with four handles. Beside the vase lay a skull, on which could be made out traces of oxidation, which had probably been caused by the wearing of a metal band, which has not been found. This skull bears on the right side a little oval hole with cicatrized edges about an inch long by two fifths of an inch broad. The discovery of a bronze dagger and two bronze plaques leaves no doubt as to the age of this tumulus. This example of trepanation is the only well authenticated one of which I know in Brittany. It is true one skull has been mentioned as found beneath the megalithic monument of Saint-Picoux de Quiberon (Morbihan), which is even said to bear marks of sawing and sc.r.a.ping made in attempting trepanation, but this fact has been very much questioned, and the date at which the trepanation was performed, if performed it were, is very doubtful.[192] The proof we are seeking of the antiquity of the operation of trepanation is not therefore to be found here.

On a plain amongst the hills of the right bank of the Seine, above Paris, rises a mound resembling a promontory which is known as the Guerin mound, and consists of a vast deposit of chalk which was excavated long ago. Successive operations have brought to light eight caves, most of which contained a number of human remains, which were unfortunately dispersed without having been scientifically examined. One alone, opened in 1874, contained numerous bones belonging to individuals of every age and of both s.e.xes, with polished flints, fragments of pottery, and implements of stag-horn. Amongst these relics was found the skull of an old man showing a very curious example of trepanation. It was unfortunately broken by the workmen in the very moment of discovery, and could only be very insufficiently examined. Other examples, however, which could be properly authenticated, are not wanting from the banks of the Seine and Marne; two fragments of skull were found in the canton of Moret, one of which had been trepanned during the life of its owner, and the other after death. We must also mention the crania presented to the learned societies at the Sorbonne, one of which came from the plateau of Avrigny, near Mousseaux-les-Bray (Seine-et-Marne). Side by side with the skeleton lay polished hatchets, sc.r.a.pers, and arrow-heads, fragments of pottery blackened by smoke, and lastly a solitary bone of an ox, pierced with three holes at regular distances, which had probably been used as a flute. Of nine crania found in this excavation three were pierced, two after death and one during life, the edges of the last named bearing very evident traces of treatment.

A trepanned skull was also discovered in a Neolithic sepulchre near Crecy-sur-Morin, where lay no less than thirty skeletons, remarkable for the strongly defined section of the tibiae, whilst around were strewn hatchets, flint knives, bones, stilettos and picks of siliceous limestone with handles made of pieces of stag-horn. The tomb, built of stones without mortar, contained two contiguous chambers separated by a wall, and covered over by a stone weighing more than 1,200 tons. It seems likely that this huge stone had not been moved -- it must have been beyond the strength of the makers of the tomb to lift it, -- but that the s.p.a.ces beneath, in which the dead had been placed, had been merely hollowed out. In the covered AVENUE DES MUREAUX, of which I have already spoken, were picked up several trepanned crania. The tools, sc.r.a.pers, and piercers, which had probably been used for the operation, lay near the crania.

A Neolithic sepulchre containing three trepanned crania was opened at Dampont, near Dieppe. The operation had been as neatly executed as if it had been performed by one of our most distinguished surgeons. As at Crecy, the sepulchral crypt was divided into two chambers, and the slab between them was pierced with a square opening,[193] -- a fresh example of the curious practice of making openings, of which we have spoken in treating of so many different regions, often apparently completely cut off from communication with each other.

Beneath the Bougon dolmen (Deux-Sevres), in the west of France, was found a skull, and at Lizieres in the same department, the skeleton of a tall old man with a dolichocephalic skull and platycnemic tibiae bearing traces of old wounds badly healed. The bony tissue of the skull was in an unhealthy state and the trepanation had evidently been part of medical treatment. At Saint-Martin-la-Riviere (Vienna), a tomb dating from Neolithic times contained five trepanned crania, on one of which the perforation had been made by sc.r.a.ping. In this tomb was also found a round piece of skull with a hole in it, which had doubtless been used as a pendant. The other objects found in this sepulchre were of a remarkable character, and included hatchets made of coralline limestone, jade, fibrolite, and serpentine, the blades of flint knives, arrows, some feathered, others stalked, some necklace beads, and a number of vases, some apodal, others with flat stands, and nearly all without any attempt at ornamentation. Beneath a dolmen near St. Affrique, M. Cartailhac discovered a skull with two holes in it; one near the bregma, which had been made during life, and the other on a level with the lambda, which had not been made until after death.[194] We cannot now note the important conclusions founded on these two perforations, we must be content with adding here that the tomb contained four other skeletons with crania showing no trace of trepanation; the tibiae were platycnemic and the humeri had the so-called perforation of the olecranon farces, which certain anthropologists, as I think without sufficient reason, consider characteristic of inferior races. We must mention yet one more discovery which it will not do to omit. A human parietal with a piece missing that had evidently been taken out, was found beneath the rock-shelter of Entre-Roches near Angouleme. The skull bore very evident traces of the performance of an operation which may or may not have been executed during life. Was it done to remove the diseased bone -- for it was diseased -- in the hope of prolonging life? Did the patient die under the hands of the surgeon, or was the piece of bone taken out after death to be used as an ornament or an amulet? Any one of these hypotheses is possible, and all we can say for certain is that there is no sign of the wound having been healed in any way. This is a common thing enough, and the interest of the discovery arises from a different cause. The rock-shelter of Entre-Roches is supposed to date from Paleolithic times, and if it were certain that there has been no displacement of the soil on which the parietal was found, it is to be concluded that trepanation was practised in the Quaternary period when man was living amongst the large extinct pachydermata and felidae. But it will be difficult to admit this unless other discoveries confirming it are made. If, however, we cannot prove that trepanation was practised in France in Palaeolithic times, we can a.s.sert that it was continued down to the earliest centuries of the Christian era. One remarkable case of trepanation was found, for instance, in the Merovingian cemetery near St. Quentin; and a trepanned skull was recently exhibited at a meeting of the Anthropological Society in Paris, which had been found beneath a Merovingian tomb at Jeuilly. The patient had long survived his wound. The skeleton was found in a stone trough, narrower at the foot than at the head. The skeleton of a man between forty and fifty years of age was found in a Frank cemetery at Limet, near Liege. On the left parietal of the skull was an oval hole as big as a pigeon's egg, bearing traces of having been medically treated. The patient, like the man of Jeuilly, certainly survived the operation. His tomb, as were the resting-places of his neighbors in death, was covered over with a huge unhewn stone, and beside him lay another skeleton. A few nails and bits of wood were the only things found in the tomb. We may also mention the skeleton of a Frank of between fifty-five and sixty-five years of age with a trepanned skull, found by M. Pilloy, in a cemetery of the St. Quentin ARRONDISs.e.m.e.nT, which also contained numerous objects dating from the sixth century A.D.

So far we have only spoken of France, but similar facts are reported all over Europe, and the difficulty really is to make a selection. Some round pieces of skull, like those of Lozere, have been picked up in Umbria[195]; and a skull, bearing traces of an operation, the aim of which was to remove a portion of the left parietal, was found in the Casa da Mouva (Portugal), which dates, as do so many in France, from Neolithic times.

Goss mentions a discovery in one of the pile-dwellings of Lake Bienne, of a skull with a large hole in it with bevelled edges. There is no trace of this wound having healed, and the patient had evidently died soon after the operation.

The Prague Museum possesses two crania found at Bilin in Bohemia; one, of a p.r.o.nounced dolichocephalic type, has near the middle of the right parietal an opening measuring one and a half by two and a third inches; the cicatrization is complete, and trepanation was evidently performed long before death. The other is mesaticephalic, and bears a round opening about one and a half inches in diameter. Dr. w.a.n.kel, to whom we owe these details, is well known through other discoveries; his excavations in the Bytchiskala Cave brought to light the skeleton of a young girl of ten or twelve years old, who bad undergone the operation of trepanation. The wound, which was on the right side of the forehead, was half healed. The child still wore the ornaments she had been fond of in life -- bronze bracelets and a necklace of large gla.s.s beads.

Discoveries of a similar character succeeded each other in Bohemia, and in nearly every case the operation of trepanation had been performed on the upper part of the forehead. Not very long ago it was reported to the Anthropological Society of Berlin that in excavating two tombs containing the remains of burnt bodies at Trupschutz, on the west of Brux, some fragments of skull were picked up, showing traces of trepanation. The edges of the wound in this case bad been healed, and the patient had lived on after the operation. Professor Virchow came to the same conclusion with regard to a skull from a Neolithic tomb which bore on the right parietal traces of an ancient cicatrized wound. He also tells us of the finding in Poland of a round piece of skull which had evidently been worn as an amulet.[196]

In the north of Europe similar discoveries have been made. At Borreby, in Denmark, a skull was found from which large pieces had been taken; and another from beneath a dolmen at Noes, in the island of Falster, had a hole in it no less than two and a quarter by one and three quarter inches in size. In the one case the holes were parts of a wound to which the victim had succ.u.mbed; in the other the edges were too regular to have been caused by traumatism. A Russian skull, a cast of which has recently been presented to the Italian Anthropological Society, bears traces of two trepanations; one performed during life, the other after death. The former had evidently been caused neither by illness nor by a wound.

General Faidherbe discovered at Roknia, in Algeria, two trepanned skulls, dating from a remote antiquity, in one of which the wound is half an inch in diameter, and shows no sign of cicatrization; and travellers speak of evident traces of similar operations on skulls dating from the time of the Ainos;, the ancestors or predecessors of the j.a.panese at the present day; and if we cross the Atlantic, we shall meet with instances of trepanations executed in a similar manner, and probably for similar reasons.

We meet with numerous examples of trepanation in America, and fresh discoveries are daily made by the energetic men of science in that country. Dr. Mantegazza[197] mentions three examples of trepanation from Peru, which are of very great interest. One skull, still bound up in many cloths, was found in the Sanja-Huara Cave (province of Anta), which had been twice trepanned, and on which yet two more attempts at trepanation bad been made. The latter seem to have taken place at different times, and death seems to have succeeded the last operation. Another skull which had belonged to an adult of Huarocondo has two frontal openings close to each other; the upper, of elliptical shape, is of large size and was evidently made after death. Yet another skull from the province of Ollantay-tambo bears a double trepanation, evidently made during life. The healing of the parietal opening proves that it was made before the wound in the forehead, in which the edges have remained rough. Dr. Mantegazza thinks that in the two first cases the operations took place after the patient had been wounded, but that in the third, the patient operated upon bad been epileptic or perhaps even insane. We find it difficult to follow the learned professor here, as w e are ignorant of the grounds for his conclusions.

We give an ill.u.s.tration (Fig. 81) of a trepanned skull found in a cemetery in the Yucay valley. A square piece has been cut out by making four regular incisions. The bone shows traces of an ancient inflammation, and many eminent surgeons, including Nelaton and Broca, have not hesitated to attribute the opening, large as it is (seven by six inches), to a surgical operation. If the incisions are carefully examined it is easy to see that they were made with the help of a pointed instrument, such as a clumsily made drill, for instance. Each incision must have taken a long time to make, and we note with ever increasing astonishment that the ancient Peruvians were not acquainted with the use of iron or steel, and that the hardest metal they employed was bronze.
