In the southwestern part of Persia is the lovely valley of Schiraz, in the province of Farsistan, which is the ancient Persis. Through the long spring and summer the plains are covered with flowers, the air is laden with perfume, and the melody of birds, winds, and waters fills the ear. The fields are covered with grain, which ripens in May; the grapes, apricots, and peaches are finer than those of Europe. The nightingale (or bulbul) sings more sweetly than elsewhere, and the rose-bush, the national emblem of Persia, grows to the size of a tree, and is weighed down by its luxuriant blossoms. The beauty of this region, and the loveliness of the women of Schiraz awakened the genius of Hafiz and of Saadi, the two great lyric poets of the East, both of whom resided here. At one extremity of this valley, in the hollow of a crescent formed by rocky hills, thirty miles northwest of Schiraz, stands an immense platform, fifty feet high above the plain, hewn partly out of the mountain itself, and partly built up with gray marble blocks from twenty to sixty feet long, so nicely fitted together that the joints can scarcely be detected. This platform is about fourteen hundred feet long by nine hundred broad, and its faces front the four quarters of the heavens. You rise from the plain by flights of marble steps, so broad and easy that a procession on horseback could ascend them. By these you reach a landing, where stand as sentinels two colossal figures sculptured from great blocks of marble. The one horn in the forehead seems to Heeren to indicate the Unicorn; the mighty limbs, whose muscles are carved with the precision of the Grecian chisel, induced Sir Robert Porter to believe that they represented the sacred bulls of the Magian religion; while the solemn, half-human repose of the features suggests some symbolic and supernatural meaning. Passing these sentinels, who have kept their solitary watch for centuries, you ascend by other flights of steps to the top of the terrace. There stand, lonely and beautiful, a few gigantic columns, whose lofty fluted shafts and elegantly carved capitals belong to an unknown order of architecture. Fifty or sixty feet high, twelve or fifteen feet in circumference, they, with a multitude of others, once supported the roof of cedar, now fallen, whose beams stretched from capital to capital, and which protected the assembled multitudes from the hot sun of Southern Asia. Along the noble upper stairway are carved rows of figures, which seem to be ascending by your side. They represent warriors, courtiers, captives, men of every nation, among whom may be easily distinguished the negro from the centre of Africa. Inscriptions abound, in that strange arrow-headed or wedge-shaped character,--one of the most ancient and difficult of all,--which, after long baffling the learning of Europe, has at last begun yielded to the science and acuteness of the present century.
