There is not now much difficulty in finding approximately the position of the gate Gennath, the starting point of this wall. We observe on Conder’s plan of the rock site that a narrow ridge runs north and south, immediately east of the Tower of David, and separates as a shed the broad head of the Tyropœon from the western valley. The Tyropœon deepens very suddenly, and any wall carried across it would of necessity be commanded by the ridge to the west of it. The only sensible course for the builders was to carry the wall along the ridge itself, on ground commanding all without it. Exactly along this ridge, at its western side, a wall was discovered in the year 1885, during the rebuilding of the Greek Bazaar. At a depth 15 feet below the present street Dr Merrill found two layers of stone, and at some points three, still in position; and the stones were of the same size and character as the largest of the stones in the Tower of David opposite. Broken Roman pottery was found in these excavations, and a stone ball, such as the Romans used in warfare. The discovery of these foundations enables us to lay down the second wall for a distance of 40 or 50 yards, with accuracy.[28] Thus we know where the wall began, and where it ended. Its intermediate course can only be ascertained by arguments of probability, and by mapping every bit of ancient wall uncovered in connection with building operations and the making of drains. Upon the true course of this wall depends the answer to the question whether the site of the Church of the Holy Sepulchre was without the city or within. We are contented here to adopt the line of wall arrived at by Herr Conrad Schick, who has studied the question on the ground, who is acquainted with every bit of ancient wall that has come to light, and has a reason for every twist and turn and every gate and tower here represented. It will be seen by his plan that he does not stop at the Tower of Antonia, but continues his line of wall so as to defend the northern and eastern sides of the Temple. This is required by Nehemiah’s descriptions. But when Herod enlarged the Temple courts, if not before, these portions of the wall would be interfered with--the northern portion would be removed, the eastern portion had perhaps become buried--and so Josephus is silent about them.
