I consider that this gallery was remodelled during the Roman period, because some holes in it to admit the water are no part of the original design. In the east wall is a semicircular arched door, built up, whose width and height shew that it was formerly the entrance of a passage. Along the side walls are semicircular headed apertures, which, together with the two openings of the same shape, opposite one to another, near the south end, are also no part of the original design. These two are the beginnings of conduits, one of which ran eastward down to the Pool of Bethesda; the other westward, into the Tyropoeon valley. The accumulated water and filth did not allow me to make a close examination of these, but, as far as I could see at the openings, the masonry and shape of the stones led me to think that they formed part of a Roman restoration. A short distance from these the gallery is closed by a wall, entirely of Arab work; but I made a temporary opening in it, and was able to continue my examination as far as the _Haram-es-Sherîf_; the ground of which is about 8 feet above the top of the vault. The quantity of water, earth, and filth, prevented my approaching the rock at the end, and ascertaining the means of communication with the surface at the _Haram_, but as I saw that the south-east corner was built up, I have no doubt there had been access at that point. It immediately occurred to me that the vault had originally been a passage between Bezetha and Moriah, and was the 'Strato's Tower,' where Antigonus, younger brother of Aristobulus, (the sons of John Hyrcanus,) was murdered by the treacherous devices of the Queen Alexandra[285]. After completing the examination of the interior I applied myself to the exterior, and found that the side walls rose one foot above the top of the vault; the space thus made being filled with strong masonry, so as to form a level surface of the same size as the gallery; which was covered over along the whole length by large slabs, of the size mentioned above; these, being firmly cemented together, bound into one mass the two side walls and the vaulting.
