forest of columns to bear aloft those ponderous beams of stone, without any thing tending to break the continuity of horizontal lines, by which the harmony and simplicity of the whole are seen. So accurately squared and nicely adjusted were the stones and pillars of which these temples were built, that there was scarcely need of even cement. Without noise or confusion or sound of hammers did those temples rise, since all their parts were cut and carved in the distant quarries, and with mathematical precision. And within the cella, nearly concealed by the surrounding columns, were the statues of the gods, and the altars on which incense was offered, or sacrifices made. In every part, interior and exterior, do we see a matchless proportion and beauty, whether in the shaft, or the capital, or the frieze, or the pilaster, or the pediment, or the cornices, or even the mouldings--everywhere grace and harmony, which grow upon the mind the more they are contemplated. The greatest evidence of the matchless creative genius displayed in those architectural wonders is that, after two thousand years, and with all the inventions of Roman and modern artists, no improvement can be made, and those edifices which are the admiration of our own times are deemed beautiful as they approximate the ancient models which will forever remain objects of imitation, No science can make two and two other than four. No art can make a Doric temple different from the Parthenon without departing from the settled principles of beauty and proportion which all ages have endorsed. Such were the Greeks and Romans in an art which is one of the greatest indices of material civilization, and which by them was derived from geometrical forms, or the imitation of Nature. * * * * * [Sidenote: Perfection of Grecian sculpture.]
