The width of the staircase is twenty-two feet—space sufficient to allow of ten horsemen ascending each flight of steps abreast. Altogether this ascent, which is on a plan unknown elsewhere, is pronounced to be the noblest example of a flight of stairs to be found in any part of the world. It does not project beyond the line of the platform whereto it leads, but is, as it were, taken out of it. [PLATE XLII.]
The next, and in some respects the most remarkable of all the staircases, conducts from the level of the northern platform to that of the central or upper terrace. This staircase fronts northward, and opens on the view as soon as the first staircase (A on the plan) has been ascended, lying to the right of the spectator at the distance of about fifty or sixty yards. It consists of four single flights of steps, two of which are central, facing one another, and leading to a projecting landing-place (B), about twenty feet in width; while the two others are on either side of the central flights, distant from them about twenty-one yards. The entire length of this staircase is 212 feet; its greatest projection in front of the line of the terrace whereon it abuts, is thirty-six feet. The steps, which are sixteen feet wide, rise in the same gentle way as those of the lower or platform staircase. The height of each is under four inches; and thus there are thirty-one steps in an ascent of ten feet.
The feature which specially distinguishes this staircase from the lower one already described is its elaborate ornamentation. The platform staircase is perfectly plain. The entire face which this staircase presents to the spectator is covered with sculptures. In the first place, on the central projection, which is divided perpendicularly into three compartments, are represented, in the spandrels on either side, a lion devouring a bull, and in the compartment between the spandrels eight colossal Persian guardsmen, armed with spears and either with sword or shield. Further, above the lion and bull, towards the edge of the spandrel where it slopes, forming a parapet to the steps, [PLATE XLIII., Fig. 1.] there was a row of cypress trees, while at the end of the parapet and along the whole of its inner face were a set of small figures, guardsmen habited like those in the central compartment, but carrying mostly a bow and quiver instead of a shield. Along the extreme edge of the parapet externally was a narrow border thickly set with rosettes. [PLATE XLIII., Fig. 2.] Next, in the long spaces between the central stairs and those on either side of them, the spandrels contain repetitions of the lion and bull sculpture, while between them and the central stairs the face of the wall is divided horizontally into three bands, each of which has been ornamented with a continuous row of figures. The highest row of the three is unfortunately mutilated, the upper portion of all the bodies being lost in consequence of their having been sculptured upon a parapet wall built originally to protect the edge of the terrace, but now fallen away. The middle and lowest rows are tolerably perfect, and possess considerable interest, as well as some artistic merit. The entire scene represented on the right side seems to be the bringing of tribute or presents to the monarch by the various nations under his sway. On the left-hand side this subject was continued to a certain extent; but the greater part of the space was occupied by representations of guards and officers of the court, the guards being placed towards the centre, and, as it were, keeping the main stairs, while the officers were at a greater distance. The three rows of figures were separated from one another by narrow bands, thickly set with rosettes.
The builder of this magnificent work was not content to leave it to history or tradition to connect his name with his construction, but determined to make the work itself the means of perpetuating his memory. In three conspicuous parts of the staircase, slabs were left clear of sculpture, undoubtedly to receive inscriptions commemorative of the founder. The places selected were the front of the middle staircase, the exact centre of the whole work, and the space adjoining the spandrels to the extreme right and the extreme left. In one instance alone, however, was this part of the work completed. On the right hand, or western extremity of the staircase, an inscription of thirty lines in the old Persian language informs us that the constructor was “Xerxes, the Great King, the King of Kings, the son of King Darius, the Achaemenian.” The central and left-hand tablets, intended probably for Babylonian and Scythic translations of the Persian legend, were never inscribed, and remain blank to the present day.
The remaining staircases will not require very lengthy or elaborate descriptions. They are six in number, and consist, in most instances, of a double flight of steps, similar to the central portion of the staircase which has been just described. Two of them (e and f) belonged to the building marked as the “Palace of Darius” on the plan, and gave entrance to it from the central platform above which it is elevated about fourteen or fifteen feet. Two others (c and d) belonged to the “Palace of Xerxes.” These led up to a broad paved space in front of that building, which formed a terrace, elevated about ten feet above the general level of the central platform. Their position was at the two ends of the terrace, opposite to one another; but in other respects they cannot be said to have matched. The eastern, which consisted of two double flights, was similar in general arrangement to the staircase by which the platform was mounted from the plain, excepting that it was not recessed, but projected its full breadth beyond the line of the terrace. It was decidedly the more elegant of the two, and evidently formed the main approach. It was adorned with the usual bull and lion combats, with figures of guardsmen, and with attendants carrying articles needed for the table or the toilet. The inscriptions upon it declare it to be the work of Xerxes. [PLATE XLIV.] The western staircase was composed merely of two single flights, facing one another, with a narrow landing-place between them. It was ornamented like the eastern, but somewhat less elaborately.
