The ruins of Palmyra and Balbec are very different. “No comparison can be instituted between them,” says Mr. Addison. “The ruins of Balbec consist merely of two magnificent temples, inclosed in a sort of citadel; while here, over an immense area, we wander through the ruins of long porticoes leading up to ruined temples and unknown buildings. Now we see a circular colonnade sweeping round with its ruined gateway, at either end; now we come to the prostrate walls, or ruined chambers of a temple or palace; anon we explore the recesses of a bath, or the ruins of an aqueduct; then we mount the solitary staircase, and wander through the silent chambers of the tombs, ornamented with busts, inscriptions, and niches for the coffins, stored with mouldering bones; and from the summits of funereal towers, five stories in height, we look down upon this mysterious assemblage of past magnificence; and beyond them, upon the vast level surface of the desert, silent and solitary; stretching away like the vast ocean, till it is lost in the distance, far as the eye can reach. The dwelling of man is not visible. The vastness and immensity of space strikes us with awe, and the mouldering monuments of human pride, that extend around, teach us a sad lesson of the instability of all human greatness.” Though antiquity has left nothing either in Greece or Italy, in any way to be compared with the magnificence of the ruins of Palmyra, Mr. Wood observes, that there is a greater sameness in the architecture of Palmyra than at Rome, Athens, and other great cities, whose ruins evidently point out different ages of decay. But, except four half-columns in the Temple of the Sun, and two in one of the mausoleums, the whole architecture is Corinthian, richly ornamented with some very striking beauties and some as visible faults. Through the valley of the tombs may be traced remnants of a ruined aqueduct, which formerly conducted water to the town from, at present, an unknown source; it consists of a vaulted passage running underground, covered with a fine hard stucco. In regard to the present supply, there are two rivers, the waters of which, when judiciously distributed, must have conduced greatly to the subsistence and comfort of the ancient inhabitants; but these are now allowed to lose themselves in the sand.
