The mention of the twentieth year of the tribunate of Hadrian fixes the date as the last year of his reign, A.D. 117.
The arch has been built up with loose stones, and has evidently been surrounded by a wall, to convert it into a fortified position.
The building has not suffered greatly since Bruce’s time, but it is buried almost to the level of the impost in débris. As Bruce’s sketch shows no sign of the loose masonry wall, it is possible that this may have been constructed by the Arabs; at the same time it is not improbable that he might purposely have omitted it, as having no connection with the history of the building.
