But there is also a symbolism about the position of the corner-stone, which is well worthy of attention. It is familiar to every one,--even to those who are without the pale of initiation,--that the custom of laying the corner-stones of public buildings has always been performed by the masonic order with peculiar and impressive ceremonies, and that this stone is invariably deposited in the north-east corner of the foundation of the intended structure. Now, the question naturally suggests itself, Whence does this ancient and invariable usage derive its origin? Why may not the stone be deposited in any other corner or portion of the edifice, as convenience or necessity may dictate? The custom of placing the foundation-stone in the north-east corner must have been originally adopted for some good and sufficient reason; for we have a right to suppose that it was not an arbitrary selection.[116] Was it in reference to the ceremony which takes place in the lodge? Or is that in reference to the position of the material stone? No matter which has the precedence in point of time, the principle is the same. The position of the stone in the north-east corner of the building is altogether symbolic, and the symbolism exclusively alludes to certain doctrines which are taught in the speculative science of Masonry. The interpretation, I conceive, is briefly this: Every Speculative Mason is familiar with the fact that the east, as the source of material light, is a symbol of his own order, which professes to contain within its bosom the pure light of truth. As, in the physical world, the morning of each day is ushered into existence by the reddening dawn of the eastern sky, whence the rising sun dispenses his illuminating and prolific rays to every portion of the visible horizon, warming the whole earth with his embrace of light, and giving new-born life and energy to flower and tree, and beast and man, who, at the magic touch, awake from the sleep of darkness, so in the moral world, when intellectual night was, in the earliest days, brooding over the world, it was from the ancient priesthood living in the east that those lessons of God, of nature, and of humanity first emanated, which, travelling westward, revealed to man his future destiny, and his dependence on a superior power. Thus every new and true doctrine, coming from these "wise men of the east," was, as it were, a new day arising, and dissipating the clouds of intellectual darkness and error. It was a universal opinion among the ancients that the first learning came from the east; and the often-quoted line of Bishop Berkeley, that-- "Westward the course of empire takes its way"-- is but the modern utterance of an ancient thought, for it was always believed that the empire of truth and knowledge was advancing from the east to the west.
