The Pantheon is the most perfect of all the remains of ancient Rome, and the only one of the Pagan temples that retains any thing of its original appearance. It was dedicated[176] either to Jupiter Ultor, or to Mars and Venus, or, more probably, to all the gods in general. The structure, according to Fabricius, is one hundred and forty feet high, and about the same in breadth; but a later author has increased the number to one hundred and fifty-eight. The roof is curiously vaulted, void places being left here and there for the greater strength. The statues of all the gods were in this temple; and these, according to their degrees, were of gold, silver, bronze, or marble. The portico is one hundred and ten feet long[177], by forty-four in depth, and is supported by sixteen columns of the Corinthian order. Each of the shafts of these columns is of one piece of oriental granite, and forty-two feet in height; the bases and capitals are of white marble. The whole height of the columns is forty-six feet five inches; the diameter, just above the base, is four feet ten inches; and, just beneath the capital, four feet three inches. The interior of the rotunda has a diameter of nearly one hundred and fifty feet. This building has been generally attributed wholly to Agrippa; but from careful research, Desgodetz asserts that the body of the edifice is of much earlier origin; and that Agrippa only newly modelled and embellished the inside, and added the magnificent portico. The building is circular, with a noble dome, and a fine portico of sixteen pillars of oriental granite. There are no windows, the light being admitted by a circular aperture in the dome. The fine marble with which the walls were encrusted, and the brass which covered the roof, have long since disappeared; the bare bricks alone are left. As St. Peter’s affords the best sample of modern art in Rome[178], so does the Pantheon exhibit the most satisfactory and best-preserved specimen of ancient art; for, notwithstanding the injuries it has sustained by the hands of barbarians of all ages, no signs of natural decay are yet visible; and with this magnificent model before their eyes, it appears strange, that the architects of St. Peter’s should not have accomplished their task more worthily. The Pantheon seems to be the hemispherical summit of a modern temple, taken off and placed on the ground; so it appears to us, at least, accustomed to see cupolas in the former situation only.
