On the conquest of Jerusalem by the crusaders, the crescent was torn down from the summit of this famous Mussulman Temple, and was replaced by an immense golden cross, and the edifice was then consecrated to the services of the christian religion, but retained its simple appellation of "The Temple of the Lord." William, Archbishop of Tyre and Chancellor of the Kingdom of Jerusalem, gives an interesting account of this famous edifice as it existed in his time, during the Latin dominion. He speaks of the splendid mosaic work, of the Arabic characters setting forth the name of the founder, and the cost of the undertaking, and of the famous rock under the centre of the dome, which is to this day shown by the Moslems as the spot whereon the destroying angel stood, "with his drawn sword in his hand stretched out over Jerusalem."[9] This rock he informs us was left exposed and uncovered for the space of fifteen years after the conquest of the holy city by the crusaders, but was, after that period, cased with a handsome altar of white marble, upon which the priests daily said mass. To the south of this holy Mussulman temple, on the extreme edge of the summit of Mount Moriah, and resting against the modern walls of the town of Jerusalem, stands the venerable christian church of the Virgin, erected by the Emperor Justinian, whose stupendous foundations, remaining to this day, fully justify the astonishing description given of the building by Procopius. That writer informs us that in order to get a level surface for the erection of the edifice, it was necessary, on the east and south sides of the hill, to raise up a wall of masonry from the valley below, and to construct a vast foundation, partly composed of solid stone and partly of arches and pillars. The stones were of such magnitude, that each block required to be transported in a truck drawn by forty of the emperor's strongest oxen; and to admit of the passage of these trucks it was necessary to widen the roads leading to Jerusalem. The forests of Lebanon yielded their choicest cedars for the timbers of the roof, and a quarry of variegated marble, seasonably discovered in the adjoining mountains, furnished the edifice with superb marble columns.[10] The interior of this interesting structure, which still remains at Jerusalem, after a lapse of more than thirteen centuries, in an excellent state of preservation, is adorned with six rows of columns, from whence spring arches supporting the cedar beams and timbers of the roof; and at the end of the building is a round tower, surmounted by a dome. The vast stones, the walls of masonry, and the subterranean colonnade raised to support the south-east angle of the platform whereon the church is erected, are truly wonderful, and may still be seen by penetrating through a small door, and descending several flights of steps at the south-east corner of the inclosure. Adjoining the sacred edifice, the emperor erected hospitals, or houses of refuge, for
