On the subject of Jerusalem many books in various languages have already been published; but I venture to think that there is still room for another, as most of them are open to objections of different kinds. Some authors have erred in being carried away by their subject, and disappoint the reader by substituting their own reflexions for the information that he desires to acquire. Some, with the eye of fancy, seem to behold the shades of Kings, of Prophets, and of Heroes, wandering among their tombs, or haunting the ruins of Sion; others, after a short stay in Jerusalem, return to their own homes and publish books, composed of fragments of classic lore, and the traditions they have gathered from the guides who have accompanied them in the visits to the Holy Places; some indeed going so far as to denounce as heretics and infidels all who do not lend a ready belief to these tales. Lastly, there are some who, without visiting Jerusalem, and consequently without a minute knowledge of its topography, rely upon the information they have gathered from the accounts of others, to reconstruct the ancient walls, the Temple, and other buildings, and endeavour to overthrow the conclusions which have been formed after a prolonged residence in the country and much careful observation. In the works of all these authors there is much that is interesting, but the description of what is really to be seen is always more or less defective. I have accordingly endeavoured to supply this want during my residence in the Holy City, and now present to my readers the fruits of eight years of continual labour, devoted to a study of the topography of Jerusalem upon the spot, in which I have been constantly occupied in excavating and removing the rubbish accumulated over the place during so many centuries, in retracing the walls, in examining the monuments and ancient remains, and in penetrating and traversing the conduits and vaults; so that I trust I am in a position to throw some fresh light upon the subject of Jewish Archæology. In arranging the plan of my work, I have rested chiefly upon the Bible, the traditions of the Rabbis, and the works of Josephus, and have made but little use of any other authorities upon the ancient topography of the city; but, to compensate for this, I have made excavations and watched those made by others, have formed intimacies with the inhabitants of the country, have sought for information on the spot, regardless of personal risk, have worked with my own hands under the ground, and so have obtained much knowledge of that which lies below the surface of the soil in Jerusalem; and have pursued my purpose, at one time with bribes, at another with force, and always with patience, perseverance, and courage.
