But the temples are not mysteries. They were built also by sacerdotal monarchs, in honor of the deity. They must have been enormous, perhaps the most imposing ever built by man: witness the ruins of Karnac--a temple designated by the Greeks as that of Jupiter Ammon---with its large blocks of stone seventy feet in length, on a platform one thousand feet long and three hundred wide, its alleys over a mile in length lined with colossal sphinxes, and all adorned with obelisks and columns, and surrounded with courts and colonnades, like Solomon's temple, to accommodate the crowds of worshippers as well as priests. But these enormous structures were not marked by beauty of proportion or fitness of ornament; they show the power of kings, not the genius of a nation. They may have compelled awe; they did not kindle admiration. The emotion they called out was such as is produced now by great engineering exploits, involving labor and mechanical skill, not suggestive of grace or harmony, which require both taste and genius. The same is probably true of Solomon's temple, built at a much later period, when Art had been advanced somewhat by the Phoenicians, to whose assistance it seems he was much indebted. We cannot conceive how that famous structure should have employed one hundred and fifty thousand men for eleven years, and have cost what would now be equal to $200,000,000, from any description which has come down to us, or any ruins which remain, unless it were surrounded by vast courts and colonnades, and ornamented by a profuse expenditure of golden plates,--which also evince both power and money rather than architectural genius. After the erection of temples came the building of palaces for kings, equally distinguished for vast magnitude and mechanical skill, but deficient in taste and beauty, showing the infancy of Art. Yet even these were in imitation of the temples. And as kings became proud and secular, probably their palaces became grander and larger,--like the palaces of Nebuchadnezzar and Rameses the Great and the Persian monarchs at Susa, combining labor, skill, expenditure, dazzling the eye by the number of columns and statues and vast apartments, yet still deficient in beauty and grace. It was not until the Greeks applied their wonderful genius to architecture that it became the expression of a higher civilization. And, as among Egyptians, Art in Greece is first seen in temples; for the earlier Greeks were religious, although they worshipped the deity under various names, and in the forms which their own hands did make.
