From this point of view, what concerns us most, in the first instance at least, is to know how late, rather than how early, our ancestors buried in tumuli. We have, for instance, certainly, the Bartlow Hills, just alluded to, which are sepulchres of the Roman period, probably of Hadrian's time; and we have in Denmark the tumuli in which King Gorm and his English wife, Queen Thyra Danebode, were buried in A.D. 950. We probably also may be able to fill in a few others between these two dates, and add some after even the last. Thus, therefore, we have a firm basis from which to start, and working backwards from it may clear up some difficulties that now appear insuperable.

Dolmens.

The monuments alluded to in the last section were either the rude barrows of our savage ancestors, with the ruder cists, or the chambered tumuli of a people who, when we first became acquainted with them, had attained nearly as high a degree of civilization as any Turanian people are capable of attaining. The people who erected such buildings as the Tombs of Mycenæ or Orchomenos must have reached a respectable degree of organization. They possessed a perfect knowledge of the use of metals, and great wealth in bronze at least, and had attained to considerable skill in construction. Yet it is not difficult to trace back—in imagination, at least—the various steps by which a small rude chamber in a circular mound, just capable of protecting a single body, may by degrees have grown into a richly-ornamented brazen chamber, 50 or 60 feet in diameter and of equal height. Nor is it more difficult to foresee what this buried chamber would have become, had not the Aryan occupation of Greece—figured under the myth of the return of the Heracleidæ—put a stop to the tomb-building propensities of the people. Before long it must have burst from its chrysalis state, and assumed a form of external beauty. It must have emerged from its earthen envelope, and taken a form which it did take in Africa[55] a thousand years afterwards,—a richly-ornamented podium, surmounted by a stepped cone and crowned by a stele. In Greece it went no further, and its history and its use were alike strange to the people who afterwards occupied the country.

In Italy its history was somewhat different. The more mixed people of Rome eagerly adopted the funereal magnificence of the Etruscans, and their tumuli under the Empire became magnified into such monuments as the Tomb of Augustus in the Campus Martius, or the still more gorgeous mausoleum of Hadrian, at the foot of the Vatican hill.

In like manner, it would not be difficult by the same process to trace the steps by which the rude tepés of the Tartar steppes bloomed at last into the wondrous domes of the Patan and Mogol Emperors of Delhi or the other Mahomedan principalities in the East. To do all this would form a most interesting chapter in the history of architecture, more interesting, perhaps, than the one we are about to attempt; but it is not the same, though both spring from the same origin. The people or peoples who eventually elaborated these wonderful mausoleums or domed structures affected, at the very earliest periods at which we become acquainted with them, what may be called Microlithic architecture. In other words, they used as small stones as they could use, consistently with their constructive necessities. These stones were always squared or hewn, and they always sought to attain their ends by construction, not by the exhibition of mere force. On the other hand, the people whose works now occupy us always affected the employment of the largest masses of stone they could find or move. With the rarest possible exceptions, they preferred their being untouched by a chisel, and as rarely were they ever used in any properly constructive sense. In almost every instance it was sought to attain the wished-for end by mass and the expression of power. No two styles of architecture can well be more different, either in their forms or motives, than these two. All that they have in common is that they both spring from the same origin in the chambered tumulus, and both were devoted throughout to sepulchral purposes, but in form and essence they diverged at a very early period. Long before we become acquainted with either; and, having once separated, they only came together again when both were on the point of expiring.

The Buddhist Dagobas are another offshoot from the same source, which it would be quite as interesting to follow as the tombs of the kings or emperors; for our present purposes, perhaps, more so, as they retained throughout a religious character, and being consequently freed from the ever-varying influence of individual caprice, they bear the impress of their origin distinctly marked upon them to the present day.

In India, where Buddhism, as we now know it, first arose, the prevalent custom—at least among the civilized races—was cremation. We do not know when they buried their dead; but in the earliest times of Buddhism they adopted at once what was certainly a sepulchral tumulus, and converted it into a relic shrine: just as in the early ages of Christianity the stone sarcophagus became the altar in the basilica, and was made to contain the relics of the saint or saints to whom the church was dedicated. The earliest monuments of this class which we now know are those erected by the King Asoka, about the year 250 B.C.; but there does not seem much reason for doubting that when the body of Buddha was burnt, and his relics distributed among eight different places,[56] Dagobas or Stupas may not then have been erected for their reception. None of these have, however, been identified; and of the 84,000 traditionally said to have been erected by Asoka, that at Sanchi[57] is the only one we can feel quite sure belongs to his age; but, from that date to the present day, in India as well as in Ceylon, Burmah, Siam, and elsewhere, examples exist without number.

All these are microlithic, evidently the work of a civilized and refined people, though probably copies of the rude forms of more primitive races. Many of them have stone enclosures; but, like that at Sanchi, erected between 250 B.C. and 1 A.D., so evidently derived from carpentry that we feel it was copied directly, like all the Buddhist architecture of that age, from wooden originals. Whether it was from the fashion of erecting stone circles round tumuli, or from what other cause, it is impossible now to say; but as time went on the form of the rail became more and more essentially lithic, and throughout the middle ages the Buddhist tope, with its circle or circles of stones, bore much more analogy to the megalithic monuments of our own country than did the tombs just alluded to; and we are often startled by similarities which, however, seem to have no other cause than their having a common parent, being, in fact, derived from one primæval original. There is nothing in all this, at all events, that would lead us to the conclusion that the polished stone monuments of India were either older or more modern than the rude stone structures of the West. Each, in fact, must be judged by its own standard, and by that alone.

For the proper understanding of what is to follow the distinctions just pointed out should always be borne in mind, as none are more important. Half indeed of the confusion that exists on the subject arises from their having been hitherto neglected. There is no doubt that occasional similarities can be detected between these various styles, but they amount to nothing more than should be expected from family likenesses consequent upon their having a common origin and analogous purposes. But, except to this extent, these styles seem absolutely distinct throughout their whole course, though running parallel to one another during the whole period in which they are practised. If this is so, any hypothesis based on the idea that the microlithic architecture either preceded or succeeded to the megalithic at once falls to the ground. Nor, if these distinctions are maintained, will it any longer be possible to determine any dates in succession in megalithic art from analogies drawn from what may have happened at any period or place among the builders of microlithic structures. The fact which we have got to deal with seems to be that the megalithic rude stone art of our forefathers is a thing by itself—a peculiar form of art arising either from its being adopted by a peculiar race or peculiar group of races among mankind, or from its having been practised by people at a certain stage of civilization, or under peculiar circumstances, and this it is our business to try to find out and define. But to do this, the first thing that seems requisite is to put aside all previously conceived notions on the subject, and to treat it as one entirely new, and as depending for its elucidation wholly on what can be gathered from its own form and its own utterances, however indistinct they may at first appear to be.

Bearing this in mind, we have no difficulty in beginning our history of megalithic remains with the rude stone cists, generally called kistvaens, which are found in sepulchral tumuli. Sometimes these consist of only four, but generally of six or more stones set edgeways, and covered by a cap-stone, so as to protect the body from being crushed. By degrees this kistvaen became magnified into a chamber, the side stones increasing from 1 or 2 feet in height to 4 or 5 feet, and the cap-stone becoming a really megalithic feature 6 or 10 feet long, by 4 or 5 feet wide, and also of considerable thickness. Many of these contained more than one funeral deposit, and they consequently could not have been covered up by the tumuli till the last deposit was placed in them. This seems to have been felt as an inconvenience, as it led to the third step, namely, of a passage communicating with the outer air, and formed like the chambers of upright stones, and roofed by flat ones extending across from side to side. The most perfect example of this class is perhaps that in the tumulus of Gavr Innis in the Morbihan. Here is a gallery 42 feet long and from 4 to 5 feet wide, leading to a chamber 8 feet square, the whole being covered with sculptures of the most elaborate character.
