We come once more to Donegal. On the hill-top of Beltaney, near Raphoe, there is a very massive circle formed of sixty-seven huge blocks. Here again the Stonehenge ring might be set up within the Irish circle, leaving an avenue eight paces wide all round it. The sacred fire was formerly kindled here to mark the birth of Spring. The name of the old festival of Beltane still lingers on the hill. At Culdaff in north Donegal, at the end of the Inishowen peninsula, stands another great stone circle, with which we must close our survey of these titanic monuments. We have mentioned a few only among many; yet enough to show their presence everywhere throughout the land, in the valleys or on mountain summits, in the midst of pastures or on lonely and rugged isles. One group, as we have seen, cannot be younger than ten thousand years, and may be far older. The others may be well coeval. Their magnitude, their ordered ranks, their universal presence, are a startling revelation of the material powers of the men of that remote age; they are a testimony, not less wonderful, of the moral force which dedicated so much power to ideal ends. Finally, they are a monument to remind us how little we yet know of the real history of our race. III. THE CROMLECH BUILDERS. In every district of Ireland, therefore, there remain these tremendous and solemn survivors of a mighty past. The cromlechs, with their enormous masses upheld in the air, rising among the fertile fields or daisy-dotted pastures; the great circles of standing stones, starred everywhere, in the valleys or upon the uplands, along the rough sides of heather-covered hills. They have everywhere the same aspect of august mystery, the same brooding presence, like sentinels of another world. It is impossible not to feel their overshadowing majesty. Everywhere they follow the same designs in large simplicity; inspired by the same purpose, and with the same tireless might overcoming the tremendous obstacles of their erection; they are devoted everywhere not to material and earthly ends, but to the ideal purposes of the invisible and everlasting, linked with the hidden life of those who pass away from us through the gates of death. Can we find any clue to the builders of these grand and enduring memorials, the conditions of their building, the age of our land to which they belong? If we wisely use the abundant knowledge of the past already in our possession, there is good reason to believe we can, establishing much with entire certainty and divining more.
