The traveller says, "The Kaaba is placed upon an inclined base some two feet high, and its roof being flat, it presents the appearance at a little distance of a perfect cube. The only door by which it can be entered, and which is opened two or three times a year, is on the north side, about seven feet above the ground, for which reason one cannot enter except by means of a wooden staircase. The famous 'black stone' is enshrined at the north-eastern corner of the Kaaba, near the door, and forms one of the angles of the building four or five feet above the floor of the court. It is difficult to ascertain the exact nature of this stone, as its surface has been completely worn and reduced to its present condition by the kisses and worshipping touches bestowed upon it by countless millions of pilgrims. The Kaaba is entirely covered with black silk, which envelopes its sides, leaving the roof exposed. This veil or curtain is called 'the Kesoua,' and is renewed yearly during the pilgrimage. It is brought from Cairo, where it is manufactured at the expense of the Viceroy." Up to the time of Burckhardt no such detailed account of Mecca and her sanctuary had been given to the world. For this reason we shall insert extracts from the original narrative; extracts which might indeed be multiplied, for they include circumstantial accounts of the sacred well, called Zemzem, water from which is considered as an infallible remedy for every complaint. The traveller speaks also of the "Gate of Salvation," of the Makam Ibrahim, a monument containing the stone upon which Abraham sat when he was engaged in building the Kaaba, and where the marks of his knees may still be seen, and of all the buildings enclosed within the temple precincts. Judging from Burckhardt's minute and complete description, these spots still retain their former physiognomy. The same number of pilgrims chant the same songs; the men only are no longer the same. His accounts of the feast of the pilgrimage and the holy enthusiasm of the faithful, are followed by a picture which brings before us, in the most sombre colours, the effects of this great gathering of men, attracted from every part of the world.
