So far as I know, none of these dolmen-crowned tumuli have been dug into, which is to be regretted, as it would be curious to know whether the external dolmen is the real or only a simulated tomb. My own impression would be in favour of the latter hypothesis, inasmuch as a true and a false tomb are characteristic of all similar monuments. In the pyramids of Egypt they coexisted. In every Buddhist tope, without exception, there is a Tee, which is in every case we know only a simulated relic-casket. Originally it may have been the place where the relic was deposited, and as we know of instances where relics were exposed to the crowd on certain festivals, it is difficult to understand where they were kept, except in some external case like this. In every instance, however, in which a relic has been found it has been in the centre of the Tope and never in the Tee. A still more apposite illustration, however, is found in the tombs around Agra and Delhi. In all those of any pretension the body is buried in the earth in a vault below the floor of the tomb and a gravestone laid over it, but on the floor of the chamber, under the dome, there is always a simulated sarcophagus, which is the only one seen by visitors. This is carried even further in the tomb of the Great Akbar (1556, 1605). Over the vault is raised a pyramid surrounded, not like this tumulus by three rows of stones, but by three rows of pavilions, and on the top, exposed to the air, is a simulated tomb placed exactly as this dolmen is. No two buildings could well seem more different at first sight, but their common parentage and purpose can hardly be mistaken, and it must be curious to know whether the likeness extends to the double tomb also.

This, like many other questions, must be left to the spade to determine, but, unless attention is turned to the analogy above alluded to, the purpose of the double tomb may be misunderstood, even when found, and frequently, I suspect, has already been mistaken for a secondary interment.

Circles.

Circles form another group of the monuments we are about to treat of, in this country more important than the dolmens to which the last section was devoted. In France, however, they are hardly known, though in Algeria they are very frequent. In Denmark and Sweden they are both numerous and important, but it is in the British Islands that circles attained their greatest development, and assumed the importance they maintain in all the works of our antiquaries which treat of megalithic art.

The cognate examples in the microlithic styles afford us very little assistance in determining either the origin or use of this class of monument. It might, nay has been suggested, that the podium which surmounts such a tumulus, for instance, that of the Cocumella ([woodcut No. 5]) would, if the mound were removed, suggest, or be suggested, by the stone circles of our forefathers. This podium, however, seems always to have been a purely constructive expedient, without any mystic or religious significance, for unless the base of an earthen mound is confined by a revêtement of this sort it is apt to spread, and then the whole monument loses that definition which is requisite to dignity.

The Rails of the Indian Buddhists at first sight seem to offer a more plausible suggestion of origin, but it is one on which it would be dangerous in the present state of our knowledge to rely too much; if for no other reason, for the one just given, that up to the time of Asoka, B.C. 250, they, like all the architecture of India, were in wood and wood only. Stone as a building material, either rude or hewn, was unknown in that country till apparently it was suggested to them by the Bactrian Greeks. Unless, therefore, we are prepared to admit that all our stone circles are subsequent, by a considerable interval of time, to the epoch of Asoka, they were not derived from India. My own impression is that all may ultimately prove to have been erected subsequently to the Christian Era, but till that is established we must look elsewhere than to India for our original form, and even then we have only got a possible analogy; and nothing approaching to a proof that any connexion existed between them.

The process in this country, so far as I can make out, was different, though tending to a similar result. The stone circles in Europe appear to have been introduced in supercession to the circular earthen mounds which surround the early tumuli of our Downs. These earthen enclosures still continued to be used, surrounding stone monuments of the latest ages, but, if I mistake not, they first gave rise to the form itself. Such a circle, for instance, as that called the Nine Ladies on Stanton Moor, I take to be a transitional example. The circular mound, which is 38 feet in diameter, enclosed a sepulchral tumulus, as was, no doubt, the case from time immemorial, but, in this instance, was further adorned and dignified by the circle of stones erected upon it. A century or so afterwards, when stone had become more recognized as a building material, the circular mound may have been disused, and then the stone circle would alone remain.
