There exist also monuments, or rather fragments of edifices, of the most primitive antiquity, which, as they are connected with the subject under discussion, are here deserving of a slight notice. I allude to those Cyclopean walls, which are to be found in several parts of Italy, and which those who have once seen will not easily forget, nor the singular stamp of antiquity they bear. In this very peculiar architecture, we see, instead of the stones of the usual cubical or oblong form, huge fragments of rock rudely cut into the shape of an irregular polygon, and skilfully enough joined together. Even the great, and often admired, subterraneous aqueduct, or Cloaca of ancient Rome is considered as belonging to this cyclopean architecture, remains of which exist also near Argos and in several other parts of Greece. These edifices were certainly not built by the celebrated nations that at a later period occupied those countries; for even they regarded them as the work and production of a primitive and departed race of giants; and hence the name which these monuments received. When we consider how very imperfect must have been the instruments of those remote ages, and that they cannot be supposed to have possessed that knowledge in mechanics which the Egyptians, for instance, display in the erection of their obelisks; we can easily conceive how men were led to imagine that more vigorous arms and other powers, than those belonging to the present race of men, were necessary to the construction of those edifices of rock. Thus have we now endeavoured to explain, as far as was necessary for our purpose, the origin of that dissension, which is inherent in human nature, and forms the basis of all history. We have in the next place sought to unfold and illustrate the universal tradition, which attests the hostility between the virtuous Patriarchs and the proud Titans of the primitive world, or the different and opposite spirit that characterized the two primitive races of mankind; assigning, at the same time, to savage nations, or to the more degraded portions of human kind, their proper place in history--a place important undoubtedly, but still secondary in the great scheme of humanity.
