Dolmen at Proleek, Ireland

      A dolmen, it may be here explained, is a kind of chamber composed of upright unhewn stones, and roofed generally with a single huge stone. They are usually wedge-shaped in plan, and traces of a porch or vestibule can often be noticed. The primary intention of the dolmen was to represent a house or dwelling-place for the dead. A cromlech (often confused in popular language with the dolmen) is properly a circular arrangement of standing stones, often with a dolmen in their midst. It is believed that most if not all of the now exposed dolmens were originally covered with a great mound of earth or of smaller stones. Sometimes, as in the illustration we give from Carnac, in Brittany, great avenues or alignments are formed of single upright stones, and these, no doubt, had some purpose connected with the ritual of worship carried on in the locality. The later megalithic monuments, as at Stonehenge, may be of dressed stone, but in all cases their rudeness of construction, the absence of any sculpturing (except for patterns or symbols incised on the surface), the evident aim at creating a powerful impression by the brute strength of huge monolithic masses, as well as certain subsidiary features in their design which shall be described later on, give these megalithic monuments a curious family likeness and mark them out from the chambered tombs of the early Greeks, of the Egyptians, and of other more advanced civilizations. The dolmens proper gave place in the end to great chambered mounds or tumuli, as at New Grange, which we also reckon as belonging to the Megalithic People. They are a natural development of the dolmen. The early dolmen-builders were in the neolithic stage of culture, their weapons were of polished stone. But in the tumuli not only stone, but also bronze, and even iron, instruments are found—at first evidently importations, but afterwards of local manufacture.

      Origin of the Megalithic People

The language originally spoken by this people can only be conjectured by the traces of it left in that of their conquerors, the Celts.2 But a map of the distribution or their monuments irresistibly suggests the idea that their builders were of North African origin; that they were not at first accustomed to traverse the sea for any great distance; that they migrated westwards along North Africa, crossed into Europe where the Mediterranean at Gibraltar narrows to a strait of a few miles in width, and thence spread over the western regions of Europe, including the British Islands, while on the eastward they penetrated by Arabia into Asia. It must, however, be borne in mind that while originally, no doubt, a distinct ethnicity, the Megalithic People came in the end to represent, not ethnicity, but a culture. The human remains found in these sepulchres, with their wide divergence in the shape of the skull, &c., clearly prove this.3 These and other relics testify to the dolmen-builders in general as representing a superior and well-developed type, acquainted with agriculture, pasturage, and to some extent with seafaring. The monuments themselves, which are often of imposing size and imply much thought and organised effort in their construction, show unquestionably the existence, at this period, of a priesthood charged with the care of funeral rites and capable of controlling large bodies of men. Their dead were, as a rule, not burned, but buried whole—the greater monuments marking, no doubt, the sepulchres of important personages, while the common people were buried in tombs of which no traces now exist.

      The Celts of the Plains

De Jubainville, in his account of the early history of the Celts, takes account of two main groups only—the Celts and the Megalithic People. But A. Bertrand, in his very valuable work “La Religion des Gaulois,” distinguishes two elements among the Celts themselves. There are, besides the Megalithic People, the two groups of lowland Celts and mountain Celts. The lowland Celts, according to his view, started from the Danube and entered Gaul probably about 1200 B.C. They were the founders of the lake-dwellings in Switzerland, in the Danube valley, and in Ireland. They knew the use of metals, and worked in gold, in tin, in bronze, and towards the end of their period in iron. Unlike the Megalithic People, they spoke a Celtic tongue,4 though Bertrand seems to doubt their genuine racial affinity with the true Celts. They were perhaps Celticised rather than actually Celtic. They were not warlike; a quiet folk of herdsmen, tillers, and artificers. They did not bury, but burned their dead. At a great settlement of theirs, Golasecca, in Cisalpine Gaul, 6000 interments were found. In each case the body had been burned; there was not a single burial without previous burning.

      This people entered Gaul not (according to Bertrand), for the most part, as conquerors, but by gradual infiltration, occupying vacant spaces wherever they found them along the valleys and plains. They came by the passes of the Alps, and their starting-point was the country of the Upper Danube, which Herodotus says “rises among the Celts.” They blended peacefully with the Megalithic People among whom they settled, and did not evolve any of those advanced political institutions which are only nursed in war, but probably they contributed powerfully to the development of the Druidical system of religion and to the bardic poetry.

      The Celts of the Mountains

      Finally, we have a third group, the true Celtic group, which followed closely on the track of the second. It was at the beginning of the sixth century that it first made its appearance on the left bank of the Rhine. While Bertrand calls the second group Celtic, these he styles Galatic, and identifies them with the Galatæ of the Greeks and the Galli and Belgæ of the Romans.

      The second group, as we have said, were Celts of the plains. The third were Celts of the mountains. The earliest home in which we know them was the ranges of the Balkans and Carpathians. Their organisation was that of a military aristocracy—they lorded it over the subject populations on whom they lived by tribute or pillage. They are the warlike Celts of ancient history—the sackers of Rome and Delphi, the mercenary warriors who fought for pay and for the love of warfare in the ranks of Carthage and afterwards of Rome. Agriculture and industry were despised by them, their women tilled the ground, and under their rule the common population became reduced almost to servitude; “plebs pœne servorum habetur loco,” as Caesar tells us. Ireland alone escaped in some degree from the oppression of this military aristocracy, and from the sharp dividing line which it drew between the classes, yet even there a reflexion of the state of things in Gaul is found, even there we find free and unfree tribes and oppressive and dishonouring exactions on the part of the ruling order.

Yet, if this ruling civilization had some of the vices of untamed strength, they had also many noble and humane qualities. They were dauntlessly brave, fantastically chivalrous, keenly sensitive to the appeal of poetry, of music, and of speculative thought. Posidonius found the bardic institution flourishing among them about 100 B.C.,and about two hundred years earlier Hecatæus of Abdera describes the elaborate musical services held by the Celts in a Western island—probably Great Britain—in honour of their god Apollo (Lugh).5 Aryan of the Aryans, they had in them the making of a great and progressive nation; but the Druidic system—not on the side of its philosophy and science, but on that of its ecclesiastico-political organisation—was their bane, and their submission to it was their fatal weakness.

      The culture of these mountain Celts differed markedly from that of the lowlanders. Their age was the age of iron, not of bronze; their dead were not burned (which they considered a disgrace), but buried.

      The territories occupied by them in force were Switzerland, Burgundy, the Palatinate, and Northern France, parts of Britain to the west, and Illyria and Galatia to the east, but smaller groups of them must have penetrated far and wide through all Celtic territory, and taken up a ruling position wherever they went.

      There were three peoples, said Cæsar, inhabiting Gaul when his conquest began; “they differ from each other in language, in customs, and
