Even more interesting than these for our present purposes was the discovery a few years later of human remains in the valleys of the Dordogne and other rivers of the south of France. Here geology does not help us, but climatology does. At that time the climate of the south of France was so cold that the inhabitants of these caves had all the habits of people now dwelling in the Arctic regions. Their principal domestic animal was the reindeer, but they were familiar with the woolly-haired mammoth, the cave bear, and the aurochs. The climate was so cold that they could throw on one side the débris of their feasts, and floor their dwelling with marrow bones and offal without dreading pestilence or even suffering inconvenience. They were, in fact, in every respect, so far as we have the means of judging, identical with the Esquimaux of the present day, and must have inhabited a climate nearly similar to that of Arctic North America. How long ago was this? We know from the pictures in the tombs near the pyramids that the climate of Egypt was the same 5000 or 6000 years ago as it is now, and we have no reason to suppose that, while that of the southern shores of the Mediterranean remained unchanged, the northern would vary in any very different ratio. Clearing of forests may have done something, but never could have accounted for such a change as this. If we take 50,000 or 60,000 years instead of 5000 or 6000, it will not suffice for such a revolution, though geologists will be wroth if we assume only 100,000; as a convenient number this will answer our present purposes.
Having at least this space of time at their disposal, the tendency of modern antiquaries has been to sweep everything into this great gulf. Why, they ask, may not Stonehenge and Avebury be 10,000, 20,000, or 50,000 years old? Man then existed, and why may he not have erected such monuments as these? Of course he might, but there is no proof that he did, and as no single tangible reason has yet been adduced for supposing them so old, the mere presumption that they might be so cannot count for much.
To my mind the force of argument seems to tend the other way. If a race of men lived on the face of the globe for 100,000 years so utterly unprogressive as these cave men, incapable of discovering the use of metals for themselves during that long period, or even of adopting them from Egypt and the East, where bronze certainly, and most probably iron, were known at least 6000 or 7000 years ago; if this people used flint and bone during all this period, is it likely that they would adopt new-fangled implements and new customs the first time they were presented to them? The Esquimaux have been familiar with the Danish settlers in Greenland for some centuries, and could easily have procured improved implements and many of the advantages of civilization had they been so inclined. They have not been changed a hair's-breadth by the influence of the stranger. The red man of North America has been in contact with the white man for centuries now. Has he changed, or can he change? In Alaska, and to the northward of Vancouver's Island, there is a race of savages, called Hydahs, with all the artistic tastes and faculties of the men of the Dordogne caves, and with about the same degree of civilization.[22] All these are dying out, and may soon disappear, but they present at this day exactly the same phenomenon as we see in the south of France, say 10,000 years ago. They have been exterminated in all the civilized parts of Europe by the progressive Aryan races who have usurped their places; and it seems only too certain that, like them, their American kindred must perish before the growing influence of the white man, but they cannot change. In so far as we can judge from such facts as are before us, if any family of this old people still lurked among our hills or on any rocky island, their habits, or customs, and their implements, would be as like those of the cave men as those of the Esquimaux or Alaska savages are at the present day. It appears most unphilosophical to apply to those people the principles of progress that are found among the higher races of mankind, and to represent them as eagerly seizing on any improvement offered them, and abandoning their old faith and their old habits at the bidding of any wandering navigator that visited their shores.
This is not the place to enter on such an enquiry, but so far as can at present be seen, it seems that mankind has progressed not so much by advance within the limits of certain races as by the superposition of more highly organized races over those of an inferior class. Thus we have those stone men of the caves who possessed the world for 100,000 or a million of years, and made no more progress in that period than the animals they were associated with. Even the progress from a chipped to a polished stone implement seems to have been taught them by a foreign bronze-using people. We have then such races as the Egyptian, the Chinese, or the Mexican, who can progress to a certain point, but stop and cannot go beyond; and, lastly, we have the Aryans, the last to appear in the field, but the most energetic, and the only truly progressive race. Our great error in reasoning with regard to the older races seems to be that we insist on applying to them the reasoning and principles which guide us, but which are wholly inapplicable to the less progressive races of mankind.
All this will be plainer in the sequel; but in the meanwhile it may safely be asserted that, up to this time, no royal road has been discovered that leads to an explanation of our megalithic antiquities. No one has yet been able so to classify the contents of cognate monuments as to construct a chronometric scale which is applicable for the elucidation of their dates; and no à priori reasoning has been hit upon that is of the smallest use in explaining either their age or their peculiarities. The one path that seems open to us is a careful examination of each individual monument, accompanied by a judicial sifting of all or any traditions that may attach to it, and aided by a comparison with similar monuments in other countries. By this means we have a chance of arriving at a fair proximate degree of certainty; for, though no one monument will tell its own tale directly, a multitude of whispers from a great number may swell into a voice that is clear and distinct and be audible to every one; while no system yet invented, and no à priori reasoning, can lead to anything but deepening the ignorance that now prevails on the subject. This is especially true with regard to the great megalithic circles in this country. With the rarest possible exceptions, no flint and no bronze or iron implements have been found within their precincts. They cannot be older than the invention of flint implements, and iron has been in continuous use since the art of smelting its ores was first discovered. If, therefore, they have no written or traditional history which can be relied upon, their age must for ever remain a mystery. The conviction, however, under which this book is written is that such a history does exist; that, when all the traditions attached to the monuments are sifted and weighed, they amount to such a mass of circumstantial evidence as suffices to prove the case and to establish the main facts of their history and use, wholly independently of any system or of any external testimony.
Direct literary evidence, in the sense in which the term is usually understood, cannot be said to exist. As before mentioned, no classical author alludes, either directly or indirectly, to these megalithic structures; yet they could not have been ignorant of them if they existed. When Cæsar and his army witnessed the fight between his galleys and the fleet of the Veneti in the Morbihan, he must have stood—if he occupied the best place—on Mont St. Michel, if it then existed, and among the stone avenues of Carnac. Is it likely that such an artist would have omitted the chance of heightening his picture by an allusion to the "standing stones" of Dariorigum? The Romans occupied Old Sarum probably during the whole time they remained in this island, and the Via Badonica passed so immediately under Silbury Hill that they could not have been ignorant of either Stonehenge or Avebury. Nor in France could they possibly have missed seeing the numerous dolmens with which the country is covered. Notwithstanding all this, the silence is absolute. The circular temple of the Hyperboreans is the only thing any one has ever pretended to quote against this; and that, for reasons given above being inadmissible, any argument based on it falls to the ground.
Neither Cæsar nor Tacitus, though describing the religious observances of our forefathers, make any mention of temples; nor, indeed, does any other classical author. Tacitus[23] tells us that the Germans worshipped only in groves; and though this is hardly to the point, his relations with Agricola were so intimate that had the Gauls and Britons had temples of stone, he could hardly have avoided alluding to them. The inference from Cæsar and all the other authors is the same, but there is no direct evidence either way.
There is no passage in any classical authors which connects the Druids, either directly or indirectly, with any stone temples or stones of any sort. Dracontia are wholly the creation of Dr. Stukeley's very fertile imagination.
So far, therefore, as negative evidence goes, it is complete in showing that our megalithic circles did not exist in the time of the Romans, and that they were not temples. Unfortunately, however, no amount of negative evidence is sufficient to prove an affirmative, though it may suffice to establish a strong presumption in favour of a particular view, and, at all events, clears the way for the production of any direct evidence which we may have. The direct written evidence that has been adduced is, however, of the most shadowy character. It amounts to little more than this:—that every allusion to these monuments in mediæval authors, every local tradition, every scrap of intelligence we have regarding them, points to a post-Roman origin. No writer, of any age or country, suggested their being prehistoric or even pre-Roman before the age of Stukeley,—say 1700.
