Cæsar relates of the Gauls that they burned their honoured dead, consuming along with them not only the things they most esteemed when alive, but also their dogs and horses, and their favourite servants and retainers.[57] Without any reference to this remarkable passage, it is scarcely possible to overlook the evidence which suggests the idea of some such Suttee system having prevailed among the aboriginal Britons, when observing the opening of a large tumulus, as it discloses its group of cists or urns, or of both combined. It seems hardly reconcilable with the general customs or ideas of a primitive community, to suppose that the earthen pyramid was systematically husbanded by its ancient builders like a modern family vault, or disturbed anew for repeated interments, unless by those who had lost all remembrance of its original object. Towards the close of the Pagan era, and in that transition-period which extends in Scotland from the fifth to about the ninth century, during which the rites of the new faith were still blended with older Pagan customs, it was no doubt different, and regular cemeterial tumuli are found, which must have accumulated during a considerable period. These, however, differ essentially from the earlier tumuli; and if we are to suppose the whole group of urns or cists in the latter to have been deposited at once, it is difficult to conceive of any other mode of accounting for this than the one already suggested, which is so congenial to the ideas of barbarian rank, and of earthly distinctions perpetuated beyond the grave. Instances do indeed occur both of cists and urns found in large tumuli near the surface, and so far apart from the main sepulchral deposit as to induce the belief that they may have been inserted at a subsequent period; while the large chambered tumuli and cairns must be supposed to have been the burial-places of a tribe or sept. It must not be overlooked that the tumuli are not, in general, to be regarded as common graves, but as special monumental structures reserved alone for the illustrious dead; among whom, no doubt, were reckoned those who fell in battle, and over whom we may therefore conceive the surviving victors to have erected those gigantic cairns which are occasionally found to cover a multitude of the dead. But some of the Scottish cairns which have been found only to inclose a solitary cist, must have occupied the labour of months, and required the united exertions of a numerous corps of workmen, to gather the materials, and pile them up into such durable and imposing monuments.

The remembrance of how greatly the dead of a few generations outnumber the living, would alone suffice to show that the tumuli could not be common sepulchral mounds. Such a custom universally adopted for a few generations in a populous district, would surpass the effects of deluges and earthquakes, in the changes wrought by it on the natural surface of the ground. The laws of Solon interdicted the raising of tumuli on account of the extent of land they occupied; and the Romans enacted the same prohibitory restrictions prior to the time of Cicero. We are familiar with the common modes of British sepulture, contemporaneous with the monumental tumulus; both the cist and the urn being very frequently found without any artificial increase of the superincumbent soil to mark the spot where they are deposited. Their inhumation beneath the soil, as well as the frequent occurrence of numbers together, point them out as the common and undistinguished graves of the builders of the tumuli. Where the tumulus was to be superimposed no such interment took place. The cist was constructed on the natural surface of the soil, and over this, earth brought from a distance—or occasionally cut away from the surface immediately surrounding the chosen site, so as thereby to add to its height—was heaped up and moulded into the accustomed form. In its progress the accompanying urns were disposed, frequently with little attention to regularity, in the inclosed area; nor is it uncommon to find along with these the bones of domestic animals. In the later tumuli are occasionally found the bronze bridle-bit and other horse furniture, and sometimes teeth and bones, and even the entire skeleton of the horse. The skeleton of the dog is still more frequently met with: and it is to be regretted that in Scotland the fact has hitherto been recorded without any minute observations being attempted on the skeleton, from which to ascertain its species, and perhaps thereby trace the older birthland of its master.[58] The Rev. Alexander Low, in a communication laid before the Society of Antiquaries of Scotland in 1815, refers to the entire skeleton of a horse discovered interred between two cists, where a large cairn had been demolished in the parish of Cairnie, Aberdeenshire. Other examples will come under our notice, all indicating the prevalence of the custom above referred to, so consonant with barbarian ideas of rank, and with the rude conceptions of a future state which still linger in parts of the Asiatic continent, where the philologist has traced the evidences of a common origin with the wandering tribes that found their way across the continent of Europe and peopled the British Isles. This, however, in passing: the reader will find no difficulty in separating fact from fancy when judging for himself.

The Long Barrow has been stated to belong apparently to the rude primeval period; but the number of examples which have been carefully examined are still too few to admit of very positive conclusions being assumed. A remarkable group of Scottish long barrows occurs in the immediate neighbourhood of the Pass of Keltnie, Perthshire. One of them was opened in 1837, and found to contain unburnt bones, along with which were discovered several rude horn lance-heads and pieces of bone artificially cut. The state of preservation in which these were, when compared with the rapid decay of the human remains almost immediately on their exposure to the air, opens up an interesting inquiry in relation to these primitive sepulchral deposits. The very different conditions in which the contiguous bones are found seem at first sight incompatible with the idea of their having been deposited along with the original occupants of the barrow. But the fragile texture of the human skeleton, when compared with that of the lower animals, is well known. Professor Goodsir informs me that his investigations have led him to the direct conclusion that the bones of the lower animals decay much less rapidly than those of man. The state of the skeletons of dogs and horses found in the tumuli confirms this conclusion, which is probably sufficiently accounted for by the greater delicacy of structure characterizing the human osteology. But independently of this, bone implements finished and deposited in a cist or tumulus in a perfect state, would be much less directly exposed to the influences affecting the skeleton amid the decomposition of the vascular tissues. It may be noted along with these observations on early tumuli, that a large conical cairn in the vicinity of the long barrows of Keltnie was demolished in 1836. It contained eleven cists, several of which inclosed cinerary urns, but no metallic relics were found in them.

The change to the circular tumulus is not accompanied with any indications of alteration in the arts of its constructors. Stone weapons and implements are of frequent occurrence in the latter, and particularly in the bowl barrow, though no distinctive evidence has yet been noted in relation to the most common forms of tumuli, sufficiently marked to be resolved into any general rule, save the very natural and obvious one, that the larger ones appear from their contents to be the more important. It is manifest, however, that some art was always exercised in giving to the tumulus an artificial form. Neither the bowl nor the bell shape is that which earth naturally assumes when thrown up into a heap. The form is therefore a matter worthy of further observation, and may yet prove a legitimate basis of stricter classification in reference to the era or race, than that now attempted. The bell-shaped tumuli are not very common in Scotland, but where they do occur they are generally of the larger class, though not always distinguished by any marked peculiarity in their contents. Such was found to be the case on opening the Black Knowe, which appears from a drawing of it to be a bell-shaped tumulus, and is one of the most remarkable for size in the parish of Rendale, Orkney. It was explored in February 1849 by Mr. George Petrie, a zealous Orkney antiquary, in company with Lieutenant Thomas, R.N., while engaged in the Admiralty Survey. I am informed, however, by the latter, that its shape was by no means uniform, and viewed from some points it differed little from the common bowl barrow, of which it is computed that above two thousand are still to be found scattered over the Orkney Islands alone. In the centre and on a level with the natural surface of the soil, there was found a small chamber or cist of undressed stones, measuring eighteen by twelve inches, and containing only an extremely rude cinerary urn, filled with bones and ashes mixed with clay.

Both the Enclosed and the Encircled Barrows are frequently of large dimensions, and indicate by their contents that they belong to the later era, when the metallurgic arts had been introduced. In various instances the contents of the enclosed barrow, or tumulus surrounded with an earthen vallum, clearly prove it to belong to the Roman era. In one, for example, in the neighbourhood of Rutherglen, Lanarkshire, which measured 260 feet in circumference, a gallery or long chamber was discovered, constructed of unhewn stones, and containing, among other relics, two brass vessels, which from the description appear to have been Roman patellæ. On the handle of each of them was engraved the name Congallus or Convallus. With these were deposited various native relics, including a perforated stone and three large glass beads, such as are frequently found in earlier British tumuli.[59] Examples, however, are not wanting of the enclosed barrow with contents belonging to an earlier period. One of such formed the largest of a group which occupied the summit of one of the Cathkin hills in the parish of Kilbride. It measured eighteen feet in height, and one hundred and twenty feet in diameter, and bore the name of Queen Mary's Law, from a popular tradition that the hapless Mary watched from its summit the ebbing tide of her fortunes on the fatal field of Langside. This interesting memorial, thus associated with two widely severed periods of Scottish history, afforded building materials to the district for many years, until in 1792 some workmen while employed in removing stones from it, exposed to view a vault or chamber situated towards the west side of the mound, and containing twenty-five rude cinerary urns. They were placed, as is most usual in the earlier sepulchres, with their mouths downward, and underneath each urn lay a piece of white quartz. Exactly in the centre of the cairn a rude cist was discovered measuring nearly four feet square, and among a quantity of human bones which surrounded it were two rude fibulæ of mixed metal, and an armilla or ring of cannel coal. Another fibula and an equally rude metal comb were found in one of the urns.[60]

The Crowned and the Encircled Barrows closely resemble a class of monuments which abound in Sweden and Denmark, while they are of rare occurrence in England. In the "Samlingar för Nordens Fornälskare,"[61] a variety of examples of both have been engraved; some of which have a second circle of stones placed about half-way up the mound, and a large standing stone on the summit. Such correspondence, however, is not necessarily a proof of Scandinavian origin, nor do they occur most frequently in districts of Scotland where the long residence or frequent incursions of the Norwegians would lead us to expect Scandinavian remains. In a large encircled barrow called Huly Hill, opened in 1830, at Old Liston, a few miles to the west of Edinburgh, a bronze spear-head was found along with a heap of animal charcoal and small fragments of bones, but neither cist nor urn. A solitary standing stone, measuring about nine and a half feet in height, occupies a neighbouring field, a little to the east of it. Another barrow which stood near the Abbey of Newbattle, East-Lothian, was of a conical form, measuring thirty feet in height, and ninety feet in circumference at the base. It formed a prominent and beautiful object in that noble demesne, surrounded at its base with a circle of standing stones, and crowned on the summit with a large fir-tree. On its removal to make way for some additions to the Abbey, it was found to contain a cist nearly seven feet long, enclosing a human skeleton. A remarkable skull preserved in the Edinburgh Phrenological Museum, and described as found in a stone coffin in a tumulus opened at Newbattle in 1782, appears to belong to this memorial mound.

One other remarkable form of barrow occasionally, though very rarely, found in Scotland, in all probability owes its origin to the Vikings who invaded and colonized our coasts at the close of the Pagan period. This consists of an oblong mound of larger size than the primitive long barrow, and terminating in a point at both ends. Some examples are also inclosed with stones, having one of considerable size at each end; and from their rarity and their remarkable resemblance to the Skibssœtninger, or ship barrow of Sweden, there can be little hesitation in assigning to them a Scandinavian origin. One of these encircled ship barrows was only demolished a few years since, on the farm of Graitney Mains, Dumfriesshire, but no record of its contents has been preserved. A much more celebrated one, and, according to venerable traditions, of undoubted native origin, is the Mound of St. Columba, at Port a Churaich, or the Bay of the Boat, which is believed to mark the spot where the Saint first landed on Iona. It measures about fifty feet in length, and is supposed to be a model of St. Columba's currach, or boat made of wicker and hides, built by him in commemoration of his landing on the sacred isle. An upright stone formerly stood at each end, and near to it is a smaller mound, representing, as is said, the little boat towed astern. In all probability an investigation of the contents of this traditional memorial would prove its sepulchral character, as has been found to be the case in other Scottish ship barrows.[62] These singular tumuli are described by Chalmers as "oblong ridges, like the hulk of a ship, with its bottom upwards." But it appears from the investigations of northern antiquaries, that this sepulchral monument was not only the mimic representation of the Vikings' ship, but that the contents of the Scandinavian Skibssœtninger seem to confirm the assertion of their sagas, that these warriors of the deep were sometimes literally burnt in their ships, and the form of the favourite scene of their triumphs renewed in the earth-work that covered their ashes.[63]

To this class probably belongs a very large earth-work, styled the Hill of Rattray, Perthshire, and perhaps also another of still larger dimensions, called Terrnavie, in the parish of Dunning, in the same county. It is a mound of earth, resembling a ship with the keel uppermost, and occupying several acres of ground. The name appears to be a corruption of terræ navis, or earth-ship, given to it on account of its form. Superstition has conferred a sacredness on it, by the association of legends evidently of primitive character. It is told that a profane hind, having proceeded to cut turfs on the side of the Terrnavie, was suddenly appalled by the vision of an old man, who appeared in the opening he had made, and after demanding, with an angry countenance and voice, why he was tirring (unroofing) his house over his head, as suddenly vanished.[64] Remains of ancient armour were dug up a few years ago, on the farm of Rossie, a little to the east of Terrnavie; of these "two helmets, a small hatchet of yellow metal, and a finger ring, are preserved in Duncruib House."[65]

The barrow was not, in all probability, entirely superseded until some time after the introduction of Christianity into Scotland. Several examples seem to indicate that the Anglo-Saxons were wont to convert an accumulating barrow into the general place of sepulture of a locality, interring the body apparently in its ordinary robes, but without any cist. Such appears to have been the tumular cemetery at Lamel Hill, near York, of which a minute account is given by Dr. Thurnam, in the Archæological Journal; and such also was a large sepulchral mound, levelled near the beach at North Berwick, East-Lothian, in 1847, in preparing a site for new gas-works. The latter was in the immediate vicinity of what appears to have been used as a general burial ground probably till a late medieval era, but its contents were clearly referrible to the Anglo-Saxon period; while in the same neighbourhood many cists and other relics of still older races have been found. This last adaptation of the primitive memorial mound as the cemetery of a whole race, ere it was abandoned along with the creed to which it had been allied, is thus beautifully referred to in the description by Dorban, an ancient Irish poet, of the Relec na Riogh, the place of interment of the kings of the Scotic race, of which the last Pagan monarch was killed in the year 406.
