We are, therefore, confronted with the visible and enduring evidence of a mighty people, spreading in two main directions from the Pillars of Hercules—eastward through Gibraltar Strait to sunny Algeria, to southern Spain and the Mediterranean isles; and northward, along the stormy shores of the Atlantic, from within sight of Africa almost to the Arctic Circle, across Spain, Portugal, France, Ireland, Britain, and the lands of the Baltic and the North Sea. Throughout this vast territory there must have been a common people, a common purpose and inspiration, a common striving towards the hidden world; there must have been long ages of order, of power, of peace, during which men’s hearts could conceive and their hands execute memorials so vast, so evidently meant to endure to a far distant future, so clearly destined to ideal ends. There must have been a great spiritual purpose, a living belief in the invisible world, and a large practical power over natural forces, before these huge monuments could be erected. Some of the stones upheld in the air in the Irish cromlechs weigh eighty or ninety or a hundred tons. If we estimate that a well-built man can lift two hundred pounds, it would demand the simultaneous work of a thousand men to erect them; and it is at least difficult to see how the effort of a thousand men could be applied.
We are led, therefore, by evidence of the solidest material reality to see this great empire on the Atlantic and along the western Mediterranean; this Atlantean land of the cromlech-builders, as we may call it, for want of a better name. As the thought and purpose of its inhabitants are uniform throughout its whole vast extent, we are led to see in them a single homogeneous race, working without rivals, without obstacles, without contests, for they seem everywhere to have been free to choose what sites they would for their gigantic structures. And we are irresistibly led to believe that these conditions must have endured throughout a vast extent of time, for no nation which does not look back to a distant past will plan for a distant future. The spiritual sweep and view of the cromlech-builders are, therefore, as great as the extent of their territory. This mysterious people must have had a life as wonderful as that of Greece or Rome or Egypt, whose territories we find them everywhere approaching, but nowhere invading.
