not known of what order were the interior columns of either chamber. Those of the western having been thirty-six feet in height, their proportion must have been nearly the same as that of the Ionic columns of the vestibule of the Propylaea, whence it seems highly probable that the same order was used in the interior of both those contemporary buildings. In the eastern chamber of the Parthenon, the smallness of the diameter of the columns leaves little doubt that there was an upper range, as in the temples of Paestum and AEgina. It is to be lamented that no remains of any of them have been found, as they might have presented some new proofs of the taste and invention of the architects of the time of Pericles. "Such was the simple construction of this magnificent building, which, by the united excellencies of materials, design, and decorations, was the most perfect ever executed. Its dimensions of two hundred and twenty-eight feet by a hundred and two, with a height of sixty-six feet to the top of the pediment, were sufficiently great to give an impression of grandeur and sublimity, which was not disturbed by any obtrusive subdivision of parts, such as is found to diminish the effects of some larger modern buildings, where the same singleness of design is not observed. In the Parthenon, whether viewed at a small or at a great distance, there was nothing to divert the spectator's contemplation from the simplicity and majesty of mass and outline, which forms the first and most remarkable object of admiration in a Greek temple; and it was not until the eye was satiated with the contemplation of the entire edifice, that the spectator was tempted to examine the decorations with which this building was so profusely adorned; for the statues of the pediments, the only decoration which was very conspicuous by its magnitude and position, being enclosed within frames, which formed an essential part of the design of either front, had no more obtrusive effect than an ornamented capital to a single column." Bearing this outline of the building in mind, the visitor may at once proceed to examine the ruins of this fine monument of ancient genius, which are deposited in the Elgin Saloon of our National Museum. First, he may notice those alto-relievos, known as the METOPES[9] OF THE PARTHENON. The subject of these sculptures has been familiarised to the visitor in the Phigaleian marbles. Here, again, is the war of the Athenians, on behalf of the Lapithae, with the Centaurs, the sculptor's subject. On entering the room, the visitor will notice various numbers on each marble: THE RED NUMBERS are those to which we refer throughout.
