these, we see three courses, which in the centre buildings are all, as I have before said, of limestone; two of the upper ones are broken about the entrance, but not cut through like the marble plinths; the lowest is entire. Each plinth advances a little, and reduces the opening to 11 feet 10.9 inches. All this we leave on the left, as not only the entrance, but all the intercolumniations have been walled up by the Turks, in order to form another battery; and ascend along the line marked by Stuart, observing the want of correspondence between the two wings, and also that from the deficiency of space on the rock, the south wing could never have been the exact counterpart of that on the north. Revett, who made this plan, has marked a column, an anta, and a square pillar between them, as if they ranged in one line, and one is apt to suppose that they might have supported a common architrave, but this does not seem to have been the case; what we have remaining to mark the place of the column and pillar, are the sinkings prepared for them in the progress of the work, which I shall hereafter explain; and the anta and pillar appear to have ranged in one line, but the column did not range with them. There are marks of a gate between the column and pillar, and perhaps of a marble slab filling up the space between the anta and pillar, but I must confess myself unable to comprehend the arrangement. We will pass from this into the inside of the building, leaving for a time its external appearance, towards the Acropolis. The upper part is now occupied by a battery, and there are no remains of the front columns rising above it, as there were in Stuart’s time, except one capital at the angle. Below is a vault, abounding in dust and dirt, where by digging and scraping, we may see the inclined plane already mentioned, as giving admission into the Acropolis, part of the old pavement, and the base of one of the Ionic columns. The inclined plane sinks below the rest of the pavement, towards the entrance, and rises above it towards the internal circuit of the Acropolis; it is transversely ribbed, to give secure footing to the horses in ascending it. Revett found a piece of the upper part of the shaft of an Ionic column, 2 feet 10 inches in diameter, and conceiving them to occupy a height of 33 feet 7 inches, he concluded from what he conceived to be the proportions of this order among the Greeks, that they must have stood on pedestals; but the base above-mentioned proves that they did not; and as the height seems correctly deduced from the surrounding parts, and we may add between one fourth and one fifth to obtain the diameter of the lower part, it follows that these columns must have been about nine and a half diameters in height.
